I have a laptop with a Li-ion battery. I am able to use it most of the time with it plugged into the AC power. So it’s plugged in all day with the battery at full charge. Is this bad for the battery? There have been other threads talking about battery “memory” for Ni-cad and other batts but nothing on this issue with Lithium batts.
