Best replacement battery

[mimiandrews]

Thanks Aironius. I have a 3-stage converter, and do not leave the trailer plugged in while in storage. A small battery maintainer is connected to take care of the battery then.

The battery that has failed ate up the maintainer, and that's what started this investigation.

I'll keep in mind what you said about weight of a battery as an indicator of quality.

Thanks TouringDan, but I don't think we'll boondock enough to justify another rebuild of that battery rack. There's a lot of plumbing, etc. in the area, and access to that is a good thing.

I have looked at the golf cart batteries, and each of those weighs almost as much as the AGM battery that I'm replacing. My interest in two batteries has to do with saving an old lady's back, not in increasing battery capacity.

I've already rebuilt the original battery support in this trailer to help it handle the weight. Original was just a piece of thin galvanized steel bent into a shelf and riveted into place. It now has a support truss welded up out of 1/2" square steel tubing underneath and that is securely mounted to the trailer floor.

Thanks everyone for the recommendations for a good battery. I think I'll go back to the wet cell type. A voltmeter and a hydrometer will tell me most of what's going on in one of those. Besides, I can buy two or three of them for what Sears charged me for that AGM.

Thanks everyone for the recommendations and for participating in the discussion.

I shopped around and the Costco batteries were the best deal for the money and warranty.

Posted from elsewhere:

For those who are interested, we are on our third set of Costco deep cycle batteries in 6 years, About every two years we need to replace them and these are just under that 2 year limit. I know some of you battery elitists are thinking, 'man, that's not lasting very long. My fancy $600 pair of agm batteries lasts 5 years before I need to replace them.' Well, that may be true, but battery life is based on the number of charge cycle they get and since we are plugged in less than 5% of the time, these go thru a lot of cycles in these same two years. Also, Costco gives me 25% credit towards new batteries if I bring them in before the 2-year mark. That means it only costs me $100 every two years to replace both batteries. That's compared to $600 every 5 years for a pair of fancy AGMs. My math tells me I am $350 ahead in those same 5 years.

I run a Sears Diehard Platinum AGM battery in my Adventure Mobile. It's a rebranded Oddessy battery. But the above post has me considering Costco's batteries for our Stream.

The converter-charger will be in the same enclosure that has your internal breaker panel. Mine is below the pull-out pantry just forward of center.

Yes, yours should be at floor level on the right hand side of the trailer about midway back. It has a black cover and you turn the small black knob 90 degrees to open it.

If you have 30 amp service, it will be the WFCO 8955 PEC power center with the converter down below the breakers and fuses.
If you have 50 amp service it will be the WFCO 9855 deck mount and a separate unit from the 8930/50 distribution panel.
Both converters are 55 amp DC output. Remember converters are rated in DC so in either configuration, 30 or 50 amp AC, you will still have a 55 amp DC converter.
