I have a Xantrex 12v rechargeable 600 Power Pack battery. Yesterday I charged it up and then attached a 12v smaller alarm battery. I forgot to check a few hours later. However, 8 hours later I disconnected the two and found the alarm battery at 11.1 volts, and the Xantrex at 0%. I'm recharging the Xantrex now. Did I somehow harm it?
