I guess charging a car battery with a charger plugged into the house
won't work if you have a load in the car like lights (or in my case a
faulty alarm). The charger will think the battery is still drawing a
fair current and isn't full, when in fact it's the load eating it up.

I've tried it with an automatic charger. If the load is enough that the
battery won't change within a certain time, the charger stops and
indicates an error.

That's just with "smart chargers" I've had 3 and they both ended up
"brain dead" and would report a shorted cell on a perfectly good
battery.

You had 3 and they BOTH ended up dead?
