Battery Charging

[arjay]

If my computer battery is completely charged and I leave it connected to the mains, am I using electricity?
Thank you

Yes it'll trickle charge your battery still . But not so much as to worry you.

But I suspect that with the mains plugged in, that'd be supplying the computer needs when on, whilst the battery simply sits there staying charged.

As OG says but you will kill the battery if you dont let it run down after charging.

You should Never fully discharge a Laptop Battery. Furthermore, a battery should Not be kept at full charge by leaving it plugged-in.
