I have two of those funky new high tech sealed 12 volt batteries running parallel.

I would have preferred 2 6 volts in series, but I was able to talk the dealer into the extra 12 volt for free. So in however many years it takes to wear these out I'll probably switch over to the 2 x 6 volt arrangement.

But in this case, you can't beat the cost v. benefit ratio!

Just getting back to everyone. We did buy two 6v Trojan 105 batteries. My husband took the trailer out for five days without electricity/water/etc hookups this last week. He said the battery light did not move at all, showed full the entire time. Thanks for all your help!

Costco Batterys

I have 2 6 volt costco golf cart battery's. They are not charging backup. I have had them for about 2 years now. I am trying to figure out if a cell is bad. I will go and get a hydrometer to test. The water looks ok in them. Basically i usually bring them in the garage after a camping trip because i don't have solar yet. i have to hook them up in series to charge because i am charging at 12 volts.

anyone have any advice? i guess i am wondering if i want to deal with this issues with the 6 volts. i guess it is a must to have a 12 volt battery as a just in case situation.

I can't help you with solving your dead battery problem too much, except to ask if Costco will take it back?

But I do have some question about Costco batteries. Did you find your batteries were one of the major brands but re-branded "Costco?

And, what is the Costco warranty on their batteries? Is it their typical full satisfaction guarantee or do they limit it to a period of time? Actually - this might help you if you are able to return it rather than dealing with it.
