I wasn't aware lead acids were so fragile. I have my old car connected to an old Bradex 4A charger 24/7, as the alarm runs the battery flat. The charger indicates it's delivering 0.5 amps after it's been sat for a while, and I've measured it at 14.4V. Surely charging a 60Ah battery at 0.5A (which is a 5 day charge!) can't possibly break it?

Unregulated chargers have killed many batteries when left on too long.
