Laptop battery capacity reduction

  adambucky 19:05 13 Feb 2019

Hi, using the battery bar app with my newly purchased (pre-owned) windows 10 laptop it is showing that my battery has wear of about 25%, the original capacity being 55Wh with current capacity reduced to of about 41Wh - as the capacity has reduced by this much does it mean its failing and capacity will continue to reduce sooner rather than later and soon not hold any charger at all - or could it still deliver the 41Wh capacity for a while longer (months or years!?)

Thanks Adam

Can't give you a time scale but maybe I can explain a little.

From the moment that anyone first uses a battery and recharges it, its capacity will be reducing. Initially it is almost unnoticeable but, as it grows it becomes more obvious.

In time you will need to replace the battery. When that will be depends very much on how you use it and how often you recharge it. At a wild guess, in probably a couple of years time.
