Now I've heard more than one such story. I'm sure it depends on the design of
the charger, so "float charger" may not be enough information.

I've got a 6 amp marine/deep cycle charger with an automatic mode. It cycles on
for a few seconds, then off for a minute or so. I don't know if that's a better
system.
