Is Your Notebook Battery Losing Life Fast? It Might Not Be a Battery Problem

I'm in Vista now too and I can't seem to figure it out. We might get lucky that it will still run on 0%, but I can't honestly remember. It did shut down at critical power for me one day, and it started up and ran for at least a half hour (that was only because thats how long I needed it, it would have run longer). Hopefully a solution is on its way.

Mystic, any updates from Asus?

 

The 95% and 100% are meaning the wear level of the battery, not the current capacity.

Actually, the wear level did not go to 100%, I think when it reaches 100%, it will automatically go to 0% wear level. So what will happen when it is 100%, I don't know.

Because everytime the battery was drained, or a re-calibration was done, the wear level will increase 5%, so, I never see the wear level reaches 100%, I only see it back to 0%.

When the wear level is 95%, the time need to fully charge the battery is no more than 30 mins, I think its around 15-25 mins. Windows will tell you the battery is 100% charged and the charge light will go off. 15 mins battery life is only a estimation. It is between 10 to 30 mins.

When the wear level go back to 0%, the charging time is much longer than when it is 95%. The charge light will go off when the battery is fully charged.

Am I explain it clearly? Tell me please.

 

OK, so even if the battery wear "wraps around" (instead of 100% it says 0% again), the battery acts as it "should" (i.e. you get approximately the full battery life). That is good and bad, i suppose.

 

Actually I am not sure what I did. I don't recommend anyone to do this. Do it at your own risk. Doing this may ruin your system.

May be there is a smarter way to do that, but I can't find.

go to
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings]
to find the values meaning, remember the entry you need to change and its value.

go to
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes]
Select a power schemes and change the coresponding value

I can't remember what i really did, since i only do it once.

May be there is a more easy way to turn it off.....

 

Yea. The capacity of the battery is wrong, and it can't calculate the remaining battery lifetime.

But Windows will tell you the battery low suddenly, and I don't know how it calculate it.

 

Well, I am starting to make some sense of what happened, with several "ifs". For instance, if they use 20-bits, unsigned the reason your current capacity is more than 10x the original makes sense. When the capacity neared 0 mWh, you subtract the loss (roughly 5% of 75900) and in an unsigned counting system, that brings you near the max of that system, which for 20-bits is 1048575. And, after a while of use, your system might thing the fully charged capacity is down to ~1 mil mWh. Further, if you lose 5% of the fully charged capacity, the wraparound makes more sense, as you would lose even more, and you would be several discharges (that trigger this) past the 0%/100% point. This could serve as an explanation, but doesn't answer the critical question - why does it do this in the first place?

 

Those of you that are interested in the program should check out http://asusbatterywear.googlepages.com/home. That is where news and new versions of my program will be. The first version will be up soon, and I am going to overhaul it for the second version. Please check it out!

 

Thank You Caleb for this program. Its good to know the REAL remaining life. I also use Ubuntu and Fedora (Linux) and all have the same problem estimating battery time. Anychance of coding for that

 

Sorry for my absence, writing exams and all, last one is on Friday. Thanks for the link Caleb.

Here's an update of what's going on, Albert from Asus, well I doubt he's doing anything about it. I have talked with Danny from MilestonePC a while ago, and he and Asus are looking into this matter.

I currently have 80% wear on my main battery and my modular bay battery has only 0-1% which I believe is normal wear, which is fine.

I am slowly but surely going to hit 100% wear soon, maybe sometime mid May.

I did find out something quite interesting, I have not done a full battery life test since I got my modular bay battery.

I generally assume things like this, 25-27 watts discharge, and the main battery is about 77whr, while the modular bay battery is 40whr. Giving me a Total of 117whr to use. This translates into 4 hours and 30 minutes of battery life, which is what I expected.

The main battery gives me about 2 hours 50 minutes - 3 hours while the modular bay battery gives me 1 hour 30 minutes to 1 hours and 45 minutes.

I always use the same optimal settings, which are, screen brightness 2/16 and 3/16, P4G is on Quiet Office, WIFI On, doing light tasks, browsing the internet and typing up documents. No USB devices, and I have disabled many unused devices like the fingerprint reader, webcam and infrared.

I have also recently undervolted my laptop using RMClock. I was expecting to replace P4G for RMClock, but P4G does a great job on battery so I now use 3 programs, NHC, RMClock and P4G all together to give me different readings for different things.

For example NHC gives me temps and the discharge rate, while RMClock allows me to undervolt, and P4G allows me to use the notebook on the battery without hindering my performance to do tasks. I have played around with RMClock to give me that same experience but it isn’t working.

Looking back at the battery wear problem, two things I came across. I recently used my main battery and totally discharged it, plus let it run at 0% charge, despite the discharge rate being a little higher, about ~28- 30 watts, my battery only lasted 1 hours while at 0%. Meaning despite my 80% wear, which should translate into about 2 hours of battery life at 0%. There’s something else going on.

Did I damage my battery while running at 0% all the time? Can the ACPI be the only one responsible for this?

To answer those questions, I figured that the first one, I don’t think this is causing any damage because once the battery is fully discharged it still finds it’s way into hibernate, meaning the battery has its own built in safety mechanism. However why did my battery not last a full 2 hours after 0%. To be honest I have no clue, it could have been another function of the battery we don’t know about.

Furthermore, regarding the ACPI, this obviously shows that it is reporting incorrect numbers, as my review states, but there’s an underlying problem. Which is the battery itself. There is a smart chip located in the battery that allows for 2 things, it reads out the health of the battery and the battery life of the battery.

I believe that many of these batteries and laptops that experience this problems have really faulty batteries and they are continued to be produced like this. Or the company who makes these batteries are purposely doing this because it makes more money for them.

In any case there is an obviously problem here, and this is definitely getting way out of my hands as I further test my own laptop.

Thanks,

MysticGolem

 

Thanks for the update Mystic. I haven't checked my wear level since I went to vista, but I need to. This might be a task for someone like Danny from MilestonePC, but I am still very curious if the wear level is the same computer to computer for the same battery. That might tell us a lot (i.e. battery problem, or computer problem). It would also be interesting to see a V6j battery in a V6va, and see how that reads (the V6va doesn't have the wear problem). That would also tell us if it is the battery or the computer (I am betting on the battery circuitry).

 

Ah I see good point, I totally forgot about that part, but your right.

Here's what I think.
1) We know by getting a new battery this will give us 0% wear, because the battery is brand new, or at least a low starting wear %.

This would make it evident that the battery is the problem.

2) By placing the worn out battery in another identical laptop, V1JP, and if that results in the same wear %, then this would also mean the battery is the problem.

3) If placing the worn out battery in another laptop sets the battery wear to 0% for some odd reason (which I doubt) then we know the ACPI is really really bad.

I plan on testing this out once my exam is done, and I will go and visit Danny at MilestonePC, but also contact the nearby Asus Support Center so I can get a new battery, since I would like a new one. I am getting a little frustrated with this now.

As I previously stated, I now do believe the battery is to blame, I also believe that the company who produces these batteries has a huge stockpile of them and doesn't know that they suffer from bad Smart Chips. Hence we would need to complain or ask them for a new design...or Asus needs to make the move in asking them for a new design just like the Z71 owners received.

It may also be already the case in which new batteries are produced that have new Smart Chips that work fine. We can already state that all the modular bay batteries work fine, V1JP, R1F, Z70va, W3J. I have not heard anyone complaining regarding their wear %. Just the main battery on some laptops.

I will be looking into this after my exam, most likely Monday, we'll see.

As for your battery life program, it is neat, works pretty much how I would like it to.

Here are some recommendations that you may already be working on for #2:
1) Allow the program to minimize to tray
2) Show the Level of Charge of both batteries
3) Have a discharge rate, like NHC does.
4) Your battery icon in the system tray needs to have options to show different things, like the battery life, or discharge rate or more.
5) An option to auto startup when you restart the computer.
6) The tool tip in which you mouse over the system tray icon should give out more information, like battery charge, discharge rate, wear % and for both batteries.

That's pretty much all I can think of, I really really dislike using NHC, but it does gives me my discharge rate, battery life, and temps for CPU and HD, if you can somehow implement temps, that would be excellent so then I would never have to open or use NHC ever again.

Thanks,

MysticGolem

 

To auto start, just drag the icon onto your startup folder.
Start_AllPrograms_startup

i agree with the points, although it is an effective piece of coding.

Will Asus let you keep the old battery or do you have to send it back?

 

Unless you BUY a new battery, you will have to send the old one back.

To the suggestions.
First, thanks, I always want ideas of what to do.
The ones I don't comment on are in the works.
But, the program does minimize to the system tray (it works properly for me and all those I have talked to), just hit the minimize button, then to bring it back double click on the tray icon. Also, it should give you information about the battery if you mouse over it. If it isn't working, send me more information at the email address listed on the site.

 

If you use the RMA yah they will want your old battery and then they will give you a new one.

As for the program, sorry yah it does minimize to the tray properly.
And yes the tool tip works, but just doesn't give enough information, just add more, like discharge rate, and temps just like NHC does.

If it is possible.

I am very interested to see Version 2 when completed.

Thanks,

MysticGolem

 

Great article, i'm sticking it in the news forum of xtremesystems.org

 

Well, I have two more days of classes, then I have 2 finals next wednesday, so I am about to get a bunch more time. The real question will be when I get more time.

A little insight on the next version. The first one was done in VB, I wrote most of it in one day, then took my time polishing it (and didn't do a great job). VB will give the most basic information about the battery. The next version will be done in Visual C++, which gives me far more things to work with, like discharge rate, things like that. This summer should give me plenty of time to work on that, and I can probably add lots of features. But, I hope that Asus fixes this before I get to that point (just cause I would rather a real, working battery).

 

Use mobilemeter for all those things (if it works in Vista, I don't know...)
BTW the latest versions of RMClock do have batt charge, discharge rate, life, but most of them are hidden under one of the tabs of the main window (can't be shown in tooltips).

 

I used MobileMeter all the time in XP, but I have yet to get it to work in Vista. Has anyone else?

 

it doesn't work in vista.

 

I believe you are correct. There IS a smart chip in the battery which keeps track of the status of the battery. It contains all the ID information (ie: how the system knows the name of the manufacturer and such) and keeps track of the battery life to prevent overcharging. Chances are, either the wrong data is being written to the chip, or the chip itself is incorrectly monitoring the battery.

Swapping a "worn" battery into another system will likely read that the battery is worn and not change anything.

I believe that this problem is probably a biasing issue. My wear level went from 3% to 8% today. I was running completely on batteries. The system lasted about two hours with the Bluetooth enabled and brightness set to varying levels (high for an hour, 2/10 for the rest). Something rather strange is that when it went to less than 10%, it seemed to take a LOT longer to go down to nothing. Every little percent below 10% seemed to last at least three times longer than at other levels. This would support the issue with battery calibration making it worse, since it completely discharges the battery before recharging it, further driving it deeper into the ditch.

Also, note that this is the first time I've ever let my batteries drop down to less than 30%. I think someone miscoded it to read the wrong values when the system is at less than 10%. NHC was NOT installed at the time (I reinstalled my laptop the other day) and the capacity value went from 72095mWh to 69255mWh. Grrr...

HP had an issue like this with their PSC inkjet printers. The ink cartridges have chips in them (for monitoring ink levels, serial number, and other stats), and the printer needed a firmware update to prevent it from writing bad data to the cartridge. Any cartridge that was screwed up in that fashion would no longer be usable, EVEN if it was still nearly full.

So I guess the workaround is, don't discharge your battery completely until they fix this. I doubt there will be a recall, and these things seem to be sealed shut.

I finally got my secondary battery, but I haven't been using it since it's rather annoying to NOT have an optical drive. Have you been using it a lot?

 

Ah yes mobile meter, an interesting little program, I currently have it set to "always on top" with transparency. Thanks for the heads up, but still I rather wait and see what Caleb can churn out of his programming abilities

I used to program using VB...more like an amature back 4 years ago, nonetheless its kool.

Just a heads up have played around some more with RMClock, I did see the discharge rate, thanks, it ok...but i'm gonna stick with Mobile meter to show me my dishcarge rate at all times which is excellent.

I am now using RMClock to deal with my power modes, I only have 1 profile, before I was trying to get 2 profiles to work, one for battery and one for AC. But the one for battery wasn't working the way I wanted it. So I now have it working the way I want it to work. I did find that undervolting to help decrease temps by just a little 1-4 degrees celcius.

Good luck on your exams.

Thanks,

MysticGolem

 

Your absolutely correct about the Smart Chip is does exactly what you say. Asus is looking into this, so far I can see two possible problems its either the battery itself or something on Asus's side, ACPI or something else. I don't know, and I tried to figure this out myself with my own laptop and countless hours of researching, testing and that's why I wrote this article. To make people aware what's going on.

But yes, Caleb was also looking into what charge % triggers this abnormal wear to come, is it 30% is it 10%? I personally don't know but yes this could be the problem in the programming.

As for your Battery I would suggest you use NHC to see your battery wear, leave the AC plugged in, remove the main battery, and plug it back in...do this 3 times, see if NHC reports different values. Then restart the notebook and see what NHC states.

I found that doing this every week or so for both my main and modular bay battery it will give the real wear % (which are still fake) but yah. I know for a fact that my modular bay battery has 0% wear, but sometimes NHC will report 1%...but I just do my process above and NHC will report 0%. Of course this doesn't work for my main battery.

As for me using my batteries, I ever since I got my modular bay battery, I have left it into the bay, I will prolly never ever use my optical drive. Last time I used it was for my review and when I did a clean install of XP Pro during X-Mas.

I am one of those people don't ever use the Optical drive, even on my desktop. So having a multi-bay like this was a big must for my laptop. The only time when I would bring my optical drive with me, is for a LAN party or a regular party because people will have DVDs and CDs and there's no way around it.

Thanks,

I am currently doing another battery life test, I have just experienced something very weird. I currently have 80%, meaning I have 40 minutes of battery life on my main battery according the Windows Battery Miser.

So I stayed looking at it, watched my Battery Charge drop to 78% and then BAM...the battery went down to 5% charge with 1 minute on all my battery misers.

This is the first time I have seen this happen. Also I will provide an update as to how long my battery will last at 0%, and then double check my battery wear % by removing my main battery and placing it back in, and then restarting the notebook.

Thanks,

MysticGolem

 

Bad news, and Caleb this is very important information for you.

My battery only lasted 40 minutes at 0%, with NHC currently reporting 80% wear. Just and FYI, at 80% Wear I am suppose to get at least 2 hours of battery life at 0%.

Now I am going to remove my main battery and put it back in and see if NHC shows a different wear % value.

Now my wear is 85%.

In my opinion this is not good, this battery problem has become quite dire, luckily there's no school for the next 1.5 weeks, but once summer school starts up, I will definitely need my 4+ hours of battery life.

I am curious as to many think that I may damage my battery doing this, removing the Critical Alarm and allowing the battery totally discharge to 0%?

However many do know the notebook will still go into hibernate once the battery is totally discharged, and in my case it did go into hibernate.

Not only has this situation became dire for me, but more interesting because I am very close to hitting my goal of 100% wear under normal conditions.

Just to clear any confusion, during my entire time of testing and discharging my battery, I have pretty much used the same settings, Screen brightness at 2/16, P4G set to Quiet Office, and now I use RMClock with the same settings at P4G Quiet Office mode, and WIFI On, while doing like tasks like web browsing and typing documents.

My discharge rate stayed at 23-25 watts, thanks to Mobile Meter, making it very easy for me to view my discharge rate while I am working, plus my temps as they change.

The temps were also quite good in my opinion while running on battery during this test, the CPU was at 46-48 degrees celcius, while the HD was at 38-40 degrees celcius.

I am curious as to what other think of this?

I am currently charging my batteries, once again NHC reports 0% wear for the modular bay battery as expected, and NHC now reports 85% wear on the main battery.

Thanks,

MysticGolem

 

I am especially curious about the 100% wear, I want to know what happens. But using your battery to 0% shouldn't harm it. The chip is supposed to shut the battery off, but I have also noticed that my past 0% life is decreasing, so maybe the chip is set wrong and we are damaging the batteries, and that is also why we get wear in the first place. (Does that make sense?)

 

I follow this thread with interest.

If MobileMeter doesn't work with Vista then I wonder if the author of MobileMeter could be contacted and asked if he would share his source code so that someone can make the necessary tweaks.

John

 

If I remember correctly, the original author was Japanese. My program should be able to provide similar battery info, but we will see, give me a little time.

 

I seriously doubt it's the cells getting damaged. I'm more inclined to think of it as a functional consequence.

The problem isn't the 0%. The problem is the upper charge limit. See, now that this chip THINKS it only has 20% of it's original capacity, there is NO way it will charge past whatever that 20% is since the problem seems to be on the lower side of the scale not counting properly and then dragging the higher side down with it. Or maybe it's finally bottoming out and reaching the actual 0% of the battery. Now if they could fix the upper part. Maybe it's not counting mWh properly...

I tried to recharge the battery past 69255mWh. No dice. It won't budge past it. There is a limiter on it to protect it from being overcharged, since if it is really overcharged, it could damage the battery and might even burst. But that's assuming it's REALLY overcharged, since in this case it's more likely a phony reading.

 

Yep, here we are wasting our time trying to figure out what is wrong, what is read incorrectly, where the bug is, making experiments, coding fixes, and in the meantime ASUS is happily selling a whole new lot of buggy batteries away...

I will try to never discharge my batteries past 30-20%. Hopefully that will increase life.

Thanks for all the insight and time spent into this, MysticGolem and Caleb.

 

AlexF I think you are right, the battery is does not seem to be charging those cells which the laptop or Smart Chip think are dead. Thus I can not run on my battery past 0% charge for 2 hours because those cells are simply not being charged anymore.

It is being limited and unfortunately I can't do anything about it.

Today's my exam, after the exam I will do a battery calibration and see what that gives me. Also I have found that there is a way to reset the battery's smart chip, google it, there's a program plus you need some kind of parallel port.

Unfortunately I haven't done much digging around for this but I will start tonight trying to find guides on how to build this parallel cable in which it is coupled with a program. This program will allow the user to reset the battery back to normal. If anyone is able to find a guide that would be great. The Software itself is free, I have a trial version, all I need is this special cable. Which some people mention you can create it for cheap.

On the defense of Asus, I highly doubt Asus knew about this until I wrote this article and made the phone call to Albert at Asus, and then told Danny at MilestonePC, who is also helping everyone get the message across. Also there are a few cases of other brands like HP and Toshiba that experience this as well if you go read through this thread for some user posts.

We still don't know if it is the battery's fault or Asus and the ACPI or something else.

Thanks,

MysticGolem

 

Just wanted to confirm, this is definitely NOT just an ASUS issue. I just got an off-lease Dell C400 that is having the same problem. NHC calculates my wear level at 70%!!

Granted, this is an old battery, but the symptoms seem exactly the same. I had it set to suspend when the battery life reached critical, but it was dying in literally 15 minutes. When it turned off, just out of curiousity I simply powered it back on, and it hummed along happily at 0% battery for close to an hour.

Figured it was a bad battery and got a new one. Bam, same problem. I don't know if C400 batteries are just prone to this, or if it's a BIOS issue on the Dell itself. I'm certainly going to follow this thread from now on though in case someone finds a fix for it.

Also, FYI, Caleb your program does not work properly on the C400. It shows the same battery info as NHC/Battery Miser. Since it was made for an ASUS that's hardly a complain, just wanted to let any other C400 users know if they find themselves here somehow

 

Well, it isn't "made for Asus", its made for Windows. Are you sure you are setting everything correctly? Also, for the time lost estimate to work, it has to start working while Windows is providing a time estimate. Email me at the address given on the site and we can work out what is going on, and if it still won't work, I will take notes so I can try to make sure it works in the next version.

 

I'm sure it's more of an issue with my computer than your program. As for "setting" stuff correctly, other than inputting the wear level, I'm not 100% what I can set here.

Interestingly, my wear level is going down 5-6% every time I do a deep discharge on this battery. It's gone down to 54% from doing this. I don't really have a way of determining whether it's increasing the life of the battery itself at all, but since I have two of these crap batteries, I'm going to just keep discharging/charging it and see what happens if I get the wear level down to zero.

 

Have you tried to do a battery calibration form the Dell bios (if it has one)? I don't know if that would help, but it sure might.

 

I checked, the Dell BIOS doesn't have one. Thanks for the tip though.

After getting the wear level down to 40% by doing deep discharges, the wear level suddenly jumped back up to 72%, so I'm stumped. With how old these are, unless some creates a miracle cure for this I'm guessing my best bet is to simply get a new one.

 

Hi all,
I own an ASUS V6 purchased in July 2006 and have found your threads on this issue very helpful. I am your typical notebook user, not particularly skilled in all the technical analysis you are writing about. I use my laptop for internet, email, powerpoint, and documents. I am not a gamer. Unfortunately, the reason I sought out this thread (and have read almost all the posts here and on previous) is because I am about to order my 3rd f&$#ing battery for my ASUS.

I have had 4 previous laptops (2 Acers and 2 IBM's) over the past 10 years and none had battery deterioration issues like my ASUS. I bought my second ASUS battery after 6 months of normal use (discharge battery to 15% and then full recharge).

So I can tell you without all the very detailed analysis noted throughout the thread, that the battery issue is very problematic and would steer me away from purchasing another ASUS.
Most guys like me who purchase laptops for business travelling do not search threads and will not find work around solutions....we vote with our feet at time of next purchase. I have even considered bailing out of my ASUS as the cost of 2 new batteries per year will eventually become so insulting that I am better off cutting my losses.

I have disabled my Critical Alarm (as suggested by previous posts) and I will see how it goes.
My amatuer analysis shows that my battery can now only fully charge to 1 hour 11 minutes.
For those of you communicating with ASUS please pass on this post.

Does anyone have any practical suggestions for me as I am quite frustrated.

 

I can only recommend what I already wrote

Of course, you will need to pay for your battery since I don't presume it's still under warranty...

It's such a pity cause the V6 is such a nice notebook I'm sure you would've been very satisfied with it if it were not for this battery issue.

 

Seems the battery problem starts coming out with the V6J users... it's like I predicted half a year ago, most of them will not notice the battery issue until it's well on the way. And now it's too late, the battery warranties have run out, the V6 is EOL, and ASUS can wash its hands nicely of all this business.

With the V1 and all the newer models that suffer from the issue, things will start coming out in a little under half a year as well.

If you sit and think of it, this is a really good way for ASUS to make money. Batteries become unusable just a little bit after their warranty runs out. So the users buy new batteries.

 

You hit the nail on the head. Manufacturers know batteries only retain their charge at acceptable levels within the first year. This is why all notebook manufacturers only warrant the battery for 1 year. They are treating it more like brake pads that you have to replace every 30,000 miles or 1 year

 

I won't mind batteries being treated as consumables if the manufacturers charged reasonable prices for replacements. 20% of the cost of the computer (in the case of the Samsung R20 I have just reviewed) is not reasonable.

John

 

Any idea how to set the power options: 'Critical battery action-->On battery' to 'Do Nothing' on Windows Vista???
I want to continue to run my computer on 0% until the battery actually runs out.

 

I have not been able to find a way to actually disable the power alarms in Vista, which is rather annoying. Let me know if you figure something out.

 

I have figured out a solution to the Windows Vista unavailable "Battery->Critical battery alarm->On battery: do nothing" problem!

Check it out!

 

Awesome - good work. I am a bit tired tonight, but I will try it in the morning.

 

Seems like my W3V is also affected by this phenomenon.

For my battery it's very bizarre and it seems to point to bad coding rather than a failure of the cells or degradation. My Capacity reads at a ridiculously high number after I did a calibration using the utility in the Asus Bios, and it seems that there is no way of reversing it as I have calibrated it several times already after a complete discharge.



Once I use the battery it quickly jumps from this number to 68000mwh range, and after about 30 minute usage it jumps/skips down 22000mwh range... Physically it feels like it has degraded to about 80-85% of it's full capacity but the battery is completely gone berserk and Windows would complain once it jumps to 68000mwh range since it's less than 7% of the fake 920560 mwh number....

I have tried to RMA this battery but ASUS refuses to do so claiming that it's out of warranty in their systems.

 

I think however that you might not be suffering from this specific problem, but instead either the battery is dying on you, or the firmware on the battery has gone bad.

I presume it's a rather old battery if it's your original W3V battery, more than a year that is... Your best bet would probably be to just buy a new one.

If it is older than 1 year then it is indeed out of warranty.

 

Not that I don't agree that the cells may be failing or degraded to a much lower level. However this degradation might have been made worst because of the coding itself, since the battery wouldn't know when it's completely charged or even discharged. The battery cycles would be disrupted to a point where it would be damaging to the cells itself.

I've had this battery for about a year now but prior to the battery reading ridiculous numbers, the wear % was increasing rapidly just like how MysticGolem was describing from just a few months use.

 

I am doubting that this is a software issue now. I was talking to an "ex-NBR member" last night, and he got his V6j fixed by having two parts replaced. I trust him that he got it working. I am getting ready to email Asus to have mine fixed. I will try to keep you updated.

 

Hym, seem to me I also suffer from fast battery wear but in other way.
My V1J's battery doesn't charge completely, I use Linux and ACPI indicator show following information:
design capacity: 75900 mWh
last full capacity: 13095 mWh

Traditionally ASUS service has no idea what to do beside sending them my laptop for inspection. We will see if they have solution beside replacing the battery.

Wow! Please, do keep us updated. If you get a solution to this problem and ever happen to pass through my town, an unlimited number of beers is guaranteed.

What were the two parts, if possible to let us know? I have changed most of my computer during RMAs to solve this issue, some components like the mainboard have been changed multiple times...

I don't think they will haveany... probably it's related to this problem, but manifests itself in a slightly more drastic way. Replace the battery, perhaps you'll have better luck with the new one...
