Make sure the max charge rate is 6 amps, 2 is better. Microprocessor controlled 3 or 4 stage charging is best and make sure it is compatible with AGM / GEL batteries. Liquid cells like in auto batteries have a different charge profile.

We have had maybe 3 or 4 failures in 12 years ? We keep 14 batteries in service, so altogether we have not had a real problem.

Listen to this man! He knows his batteries. A lot of our battery process has been taken from 1311. Including our cart.
