Question
How do I find the total capacity of my laptop battery?
Answer
As your battery gets older the total capacity it's capable of holding will decrease. Unfortunately knowing the difference between the batteries designed capacity and current total capacity is not possible with most operating systems.
To determine this detailed information install a third-party utility capable of reading and displaying the battery information. For Microsoft Windows users we suggest getting the free BatteryCare laptop battery tool.
Can I increase the total capacity?
No. Over time all rechargeable batteries will lose the some of the capacity they're capable of holding. After several years all rechargeable laptop batteries will need to be replaced.
