12 volt rv battery vs 6 volt gc batteries

[garycq]

Lately I have been having trouble with 6 volt golf cart batteries and seriously considering going to two 12 volt AGM deep cycle rechargeable batteries. Has anybody had the same frustration that I have had using two golf cart batteries and gone over to the two 12 volt batteries. I have two solar panels which should keep them charged.

These batteries may have been damaged by being discharged and not maintained. If you buy new batteries you may have the same problem. You need to monitor charging current and water periodically. I realize sometimes this a problem if an RV is in storage and can't be plugged in.

The kill switch may not shut everything off.
The batteries must be fully charged prior to going into storage.
I would have removed the batteries.

What was the voltage reading on them before storage?

The batteries were new Trojan 105 that worked when first installed. Didn't use them for several month's while in storage. Used the kill switch on the rig. When I went to do some work on it (water and was ok) the batteries didn't work so I removed them to take to my mechanic to charge. The next day he said they wouldn't hold a charge. I talked to a neighbor who is an electrical engineer and he said it could be anything including something in the trailer or even something with the batteries but he just didn't know. I can't afford this type of thing and that is why I'm considering going back to the 12 volt batteries which came with the trailer.

Maybe by telling the Forum the age of the batteries, type of trouble you're having & by what means of charging you rely on, may help.

Gary could tell about the PROBLEMS you are having, then you might get some HELP

I never had problems til I got Costco 6v's. I got 8 yrs out of T105s and 8 yrs out of Napa HD 6v's, both being maintained by a charge wizard. I just took out my Costcos this morning and checked with a hydrometer... exactly 2 yrs old and they are junk! They wouldn't even run the furnace one cycle this weekend. They were maintained by a solar smart charger. I might go back to plugging in so the charge wizard keeps them up.
Even when the costcos were new they only had 2/3 the capacity of the other two brands. I think the problem is partly Costco and partly the solar charger not being able to do the job that the charge wizard/converter can do. Craig

Same problems can exist whether it is two 6 volters or two 12 volters. Bad, poor connections, or incorrectly connected.
What is the problem or issue that you have?
