Leisure Battery Problems.
Banner AGM 92Ah
Wild camp and we had lights on in the van and heating also the fridge on Gas but the valves open.
The battery failed in about 50 mis with 5A load. Tested again once home and same again. I took the battery to Banner and they also tested it and found the same problem. Weighed it and not a problem.
They have now sent it back to the factory to see if they can find the fault. So they replaced it under warranty. I have just charged it for 2 days and then put a 5A load on it. It looks like 5 Hr to 12.3V so I will need to check again but much better.
