IMHO, you would be better off with a pair of 6V AGM golf cart batteries, like Trojan T105-AGM. Over 35% more stored power. Not cheap. You would have to order them through a golf cart distributor or solar power store.

Sorry, missed the age of them. Yeah, it is time for replacement. Get whatever will fit in battery compartment. My preference is a single batter. Fewer connections to potentially give problems. A 4D will give close to the amperage of 2 6Vs. An 8D, if there is room, more.

I just bought 4 Trojan T-105 AGM's from this www.onlinebatterysale.com source for a really good price. They were bought in December '19 and made in November '19.

They have automotive parts warehouses around the country where you pick them up. They had a Portland location, so worked well for me. Golf cart distributors/suppliers were much more expensive.

Not cheap is an understatement.

It's time.


I agree with this. If you have no diagnostic tools/skills and your battery bank won't power your system (from a known full charge) for more than a day, (or night) it's most likely time. At +-9-10 years of age, IMO, you have gotten your moneys worth, and a little more.
