Re: 12V Deep Cycle Batteries
Sweeper battery's are close to the same physical makeup as a deep cycle alternative energy battery.
Large lead plates that allow a medium to moderately high drain over a few hour period of time to 80% discharge with no damage.
For reference, Automotive battery's have thin lead plates that allow a short, high current draw, without draining more than 10% discharge before being recharged right away by the alternator when the vehicle starts.
Best way to kill almost any battery of any chemistry is to drain it completely and freeze it.
