Battery decay

I have a Lenovo 3000 V100. Now I got the notebook 6 months ago and already it has lost 30% of its capacity according to PC doctor. Such a reduction for 6 months doesnt sound right, i mean it takes longer to charge the battery than what its on time is. Would a warrenty cover this?

 

Batteries that use Li-Ion chemistry, will suffer from degradation. The rate of degradation largely depends on the way it is treated. If the temperature of the battery has been kept higher, like at 30 to 35 C, then it will have retain less charge than say a battery that has been used in the range of 20 to 25C, after a period of time. Batteries normally have a warranty on a year, so you may be able to get a replacement.

 

There's a lot of variables in determining battery longevity, such as how many charge cycles it has gone through and how it has been stored. PC Doctor is only so accurate as well. Basically the answer is no the warranty will not cover general wear and tear of the battery which is what this is. Cross your fingers and hope with the rest of us better batteries come about!

I would recommend a testing of actual battery life before worrying about the 30% wear that PC doctor is giving you. I don't put a lot of stock in those estimates, as there are so many variables that can affect the accuracy of those readings.

Make sure to calibrate your battery normally. You may also want to put it into prolonged storage if your notebook is always on AC power and in a warm environment. There is more information in the battery guide.

 

I agree with Chris on this one. I'm not sure what formula is used to come up with that total- I would assume it's something like (reported watt-hour capacity) / (reported maximum watt-hour capacity) = total % of battery life. (Mine for example would be 79 watt-hours available versus 85 a reported as my battery's maximum, which gives me 93%- keep in mind that 85 watt-hours is also an estimate by the manufacturer!)

A laptop is a lot like a car, and as everyone knows, your actual M.P.G. (or KPL) varies wildly from the manufacturer's and government reporting's estimate depending on driving habits, traffic conditions, and the like.

A real run-down test is probably called for, and calibrating your battery will provide more accurate test results. Chris' guide will give you some pointers.

 

Well in real life ordinary usage, it lasts just over an hour. But I have noted that it gets very hot while in use. Not sure if is the battery itself ir just that area of the notebook. But either way it seems it not liking the heat

 

Typically the warranties cover them when they get below 50% capacity within the 1 year battery warranty period. You could always try though.

Do the Lenovo branded laptops have the IBM power manager? If so, try the battery conditioning. I know I gained back like 15% when I did (and went back to having a battery capacity higher than the rated capacity when new).

 

Nope no power manager, And i tried to load it in but just messed up the power profiles. Bugger.
