My previous Acer laptop had a removable battery. When I first acquired it, my company IT person suggested always keeping the battery out while plugged in to help extend battery life.
Compared to other laptop users who didn't unplug and ended up with very short battery life, this was a great suggestion.
As you probably know, I can't remove my E-series battery.
So…
Have batteries improved to the point where they don't need to be removed, or is this a make money service project for Acer?
