laptop
Just to put a twist on some of what is said below, be wary of buying batteries that may have been "sitting on the shelf" for a long time. A good quality NiMH will last a year or so sitting on the shelf after coming out of the factory, but, even if the vendor recharges occasionally (which is unlikely), batteries that get several years old lose a lot of capacity, even if they don''t …
New battery causing laptop to slow down
So I purchased a new battery and after about a day my laptop started to run very slow. Whenever I plug in my laptop it runs back at normal speed but unplugged it takes forever to load things.
