So why is it now an hour or two?

I just use it a bit, and rest a bit...

I foolishly left some on for days at a time way back and
while they probably could have survived just 24 hours,
they got killed by a week online...

Odd, I've had 16 hour chargers left on for a week with no problem. But then those cells were snuggled together to get too hot.

Depends on cell and charger design, and how matched they
are to each other. Lead acid ain'tthe same as NiCad or
NiMh, but they cheaply used the same very dumb
charger, which was then used by a very dumb user...
