Depends on the charger. Many (probably all newish ones) shut
themselves off when they have finished charging the battery and don't
do any thing more until reset. If that's the case, leaving the
battery in the charger is no different from leaving it anywhere else
-- except the extra battery is more likely to be charged. The
owner's manual probably will say DO NOT LEAVE BATTERY IN CHARGER! if
it's not the case. They'll probably use bigger type, though. I
doubt there are any that do any sort of charge maintenance. The
people willing to spend that kind of money on tools use them often
enough that self-discharge shouldn't be a problem.
