I have one of those cordless drills that has a 24 volt battery. I was
wondering what would happen if I unplugged the charger from the wall,
and left the battery in it. Will the charger discharge the battery if
I dont pull it out of the charger?

Also, someone gave me an 18 volt drill that has the identical looking
battery, except the battery is an 18 volt, not a 24. That drill did
work when he gave it to me, but his charger died, and he just bought a
new drill. Can I plug that 18V battery in the 24V charger or will I
damage the battery? It does fit into the hole on the charger. I dont
think 6 volts is that much different, but it may be for the battery.

Remove the battery from the charger if you are going to unplug the
charger. Whether or not the charger will discharge the battery when
the charger is unplugged depends on its design, but why take the
chance?

Don't use a 24 volt charger on an 18 volt battery unless you want to
ruin it. Note that some chargers are designed to be able to charge
several different voltage batteries. But if it doesn't clearly state
on the label or in the instructions that it can do this, don't do it.
