Howdy -
The problem created when a battery charger is left running is can boil off
all the acid/water in the battery. More full featured chargers/maintainers
will shutoff the charge completely. I had one on my sailboat that stayed
on anytime shorepower was hooked up but it had the circuitry to prevent any
damage. It cost over $200 so the Battery Tender at <$50 is a bargain!
Bought a new one on eBay for my cars - IIRC it was ~$35 delivered.
But if you let it run overnight it shouldn't cause a problem - as long as
you check it in the morning to confirm it has sufficient acid & water in the
battery.

Yes, I know the correct answer is "Battery Tender" -- it is on my
Christmas
wish list.
But here is my question. Is there any significant damage done by leaving a
normal battery charger on overnight, where it might get to zero amps but
stay attached for a few hours? This is not a fancy battery charger that
shuts off or kicks into trickle mode or such.
I did leave it on overnight routinely last winter with no apparent damage,
but am curious about the long term impact of doing this. We're talking in
my
case one of the Interstate Battery mega-mothers under the hood, not a
cheap
off-brand battery.
