Battery

[Festus2]

If you have your two 6volts wired in series (producing 12v) then simply hook your Battery Tender to the appropriate pos and neg terminal and let the tender maintain a charge on both at the same time. I do not believe there is any need to separate them but perhaps there is some information in the Battery Minder/Tender that recommends that you do charge them separately.

If you were using a 12V regular battery charger to charge 2 6volts, you would not charge them separately. Some chargers have provision for a 6volt charge and a separate 12v charge. Not sure what the Battery Tender charging functions are: 12v only or both 6 and 12.

This describes charging two batteries in series or parallel. The problem that limits the efficiency of charging both at the same time (as described to me) is if one battery is noticably discharged more that the other.

I have to completely disconnect (not with the disconnect switch) the battery any time the rig sits unhooked, even for 24 hours. Battery will stay up for a month or more in the rig if unhooked. Any longer, its on the trickle charger in the barn.

I've just let mine sit with shore power connected. Will that not keep the batteries charged over winter? It seemed to work when we bought it in Feb during the cold weather then but this will be its first full winter.

It works just fine, you do need to check the water level and refill with distilled water if needed at least once a month.
