Dell XPS Disable/ Prevent Battery Over Charge

Hello all.

Recently acquired a Dell Xps 15 LX502.

Is there are software or switches that can disable charging or limit it to a certain amount (Eg. 80%).
My last laptop Sony Vaio CW had a program known as Vaio Battery Care which allowed me to set the limit to which the battery could be charged.

Does the Xps possess anything similar or are there 3rd party software utilities that can be downloaded?

Ps. For those of you who wonder why I'm seeking such a program it is to prevent battery overcharge which therefore prevents battery wear from being at 100% the entire time.

 

I know my last Samsung had the same thing called battery saver, my new Toshiba does not

 

In the past Ive seen how fast batteries wear down. However with that Vaio Battery Care I've passed on my old laptop to my younger brother and it still holds around 90% charge after 2 years.

I'm needing something similar for my new XPS...

 

BUMP.

Really needing some advice on battery charge limiting software to prevent battery wear.

 

Do the XPS 15's not have Dell Battery Meter?

Right click on the Windows 7 battery icon -> Dell Battery Meter -> Battery Life -> Disable Battery Charging.

The only problem is you would have to do it manually rather than set a percentage.

 

Thank you for the assistance.

 

I've tried disabling charging as described above on my L702X, and I'm fairly sure that it needs to be done after each restart. I think it can also be done in BIOS, and it still turns on charging after a restart.

My memory ain't what it used to be, so I might be wrong. However, I remove my battery and only insert it when I need it. I've got an Inspiron 8600 purchased in 2003 or 2004, and keep the battery removed 99% of the time. It still works when I need it to.

 

Yes, but if I am using my notebook as a desktop replacement and it's connected to AC all the time, does it affects battery's durability? Because it's always stays at full charge.

 

At this point, you can find references on the web that advocate leaving it in all the time, and an equal number that say it should be removed when not being used for a while. I take mine out because I almost never run it on battery. Here's a couple refs I just found.

10 Tips to make your Laptop Battery last longer

Originally I think it was a Zdnet article that got me in the habit of taking out. It said that when it's in all the time, the charger does cycle on and off. The reasoning went like this: Once it's fully charged, the charger turns off. After a while the charge drops a bit due to the nature of a lithium battery, at which point the charger kicks it again to top it off. This was deemed to be a factor that reduced battery life, not becuase of the "memory effect" which doesn't seem to affect lithium batteries, but because of the number of repeated cycles. Some sources say that circuitry in modern laptops and new battery materials make this a non-issue. I still remove mine.

 

Can someone help me, because after reinstalling windows I don't see an option for dell battery meter. Also on Dell website for xps l702 there isn't any drivers of software for this.

 

nesiojamas, you have to install Dell QuickSet Software to get this option available.

Thanks mpalandr for the info! Appreciate it.

 

On the new XPS systems, the battery automatically stops charging once it hits full charge. And if you plug it in while it is mostly (somewhere north of 90% I think) charged, it also will disable charging.
