acropolite, Kokatha man and, of course, Chris,
My apologies if my experience is in conflict with the facts. I have not had a problem with storing fully charged batteries over many months without periodic maintenance. Mind you (not that it should make much difference) I write about 6-volt 12AH SLA type units. Ah well, you live and you learn I suppose.
On the matter of paralleled batteries, whether seriesed with other batteries or not:
Would not any imbalance in the internal resistance of the battery(ies) in question result in an imbalance of current flow which, as a result, would produce a higher voltage on one set of cells compared with its 'mate'? Such a situation I would have thought would produce the effect of one set of cells topping-up, or at least attempting to, the other one. This would probably not be of significance if the difference is minor - but what about the situation where one battery has a catastrophic failure, say a short circuited cell? An open circuit I would assume would be of no consequence other than the lack of current available from that bank.
Your comments will be appreciated.
