Battery: Where did we go wrong?

[ebarker]

That battery needs to be sent to be recycled. It is bad. Either a cell shorted out or it was charged with the wrong high rate charger.

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.
