:helpsmilie: Hi Grahame, A quick question, at this moment i to am having battery problems 3x120 ah. At sundown the batteries show 13 volts capacity and to all acounts are fully charged as they will only accept 1.4amps when i have started the generator. At about 3am the remote regulator in the van is flashing showing the battery voltage at 10.8volts, and the compressa 230litre fridge is trying to cut in but can't. I turn the fridge off and the batteries go back to 12.5 volts, if i turn the fridge back on the batteries go back to 10.8volts and the fridge cuts in and out continusly. When i read the max volts it shows 13.8v, and minum 10.8v, and battery percentage of charge around 90% with 34amps used. I removed the three batteries when fully charged an let them sit for 4 days, they all remained at 13volts, i took them to not one but 4 battery places and they tested them with their equipment, an all said the batteries are good. I have since connected a 40 litre engle fridge to each of the batteries in turn and after about 4hrs they all fell to 11.8volts and after another hour the battery fell to 10.8volts and was still runing the fridge. The 3 batteries are 28 months old and to me they are throw away, but can you tell me = How come the batteries take and hold charge? When in line in the van they drop so low in say 7hrs to a point where they won't start the 230litre fridge? And when tested Three battery places say they are O.K?. Any help would be appreciated to stop me going around the bend. Cheers 32 Kev
