Call any local golf course and they should be able to steer youin the right direction. All carts use 8 volt batteries.

Re: Need 8 volt batteries HELP!!!!
The Rolls 8HHG25PM are considered dual purpose. They are deep cycle but have plenty of CCA (1549)
so work great for starting. They are what Hatteras originally used on these boats.

Re: Need 8 volt batteries HELP!!!!
It was suggested to me that I consider re-wiring so that both engines start normally on the starboard batteries and use the port bank for house loads. I would keep the ability to parallel both banks when starting if needed. That would allow true deep cycle house batteries and true start batteries for short strong loads. Good idea?
I thought the 24 819 was the OEM battery? I have a set of original fiberglass boxes in my starboard engine room and they look to be sized for a 24 battery. The current 8v/195s look small in there. I have a pair of Todd boxes on the port side where the Rolls will go and they will fit with about 1/8 to spare(I hope).Michael & Beth

Re: Need 8 volt batteries HELP!!!!
Why rewire? Moving 4/0 wire to the other side of the boat is going to be a chore, a cost, and it will probably gain you nothing. The boat is set up with battery switches in logical places in each engine room. Don't mess with the Hatteras wiring. It was really good in that era. I would leave it as is.

Re: Need 8 volt batteries HELP!!!!
Greetings. We should all join an 8V support group!
Last year, one of my starboard batteries melted a terminal so I scrambled and found the last 8 DEKAs from Nationwide Battery. Unfortunately, the trucker (or someone in the warehouse) punctured 2 of the 8 and i had to go looking again. I found 2 batteries from 2 different sources (US Battery and an Ebay special) and paid dearly for both. This season, the Sentry charger is short cycling after the batteries are fully charged and there is a .5v disparity between the port and starboard banks. Sentry Charger (very helpful) sent me a new control board with factory set cut in and cut out pots. I replaced the board and now it's better but not normal. ME Yacht Restoration in Holland Michigan is sending a tech to troubleshoot the 32V systems next week, so hopefully the gremlin will be identified.
As for batteries, Rolls is probably my next option in 4 years, so if anyone has first hand experience with them, please let us know.
Cheers

Re: Need 8 volt batteries HELP!!!!
If the charger is short cycling, I think you have a bad battery. Check each cell with a multi meter . This usually will show a problem cell. A hydrometer will give the best indication.

Re: Need 8 volt batteries HELP!!!!
If you want to have a 32v system where batteries last, buy a smart charger. The old Lamarch and Sentry chargers will not cut it. You have to do a multi-step charge and have the ability to do an equalization charge.
Analytic Systems makes a nice 32v smart charger.
Next, buy the best lead acid 8v batteries you can get. IMO, that is the Rolls. My experience is 9-11 years on a set of Rolls. My friend got 13 years out of his. Quit screwing around with those old chargers and your batteries will live a long life.Sky Cheney
