The new $$$ spiral core can be mounted sideways..
They take deep exhaustion, quick recharges..etc..
Totally sealed, so no venting, of cuz.. |

Hi:
Get the largest battery you have room for, and can afford. You can never have too much reserve.
Both Gel and AGM are sealed batteries and do not need to be vented.(unless overcharged)
GEL 's have pretty rigid charging requirements, AGM's pretty well follow conventional wet cell charging parameters.
Both cost 3-4 times what wet cells do.

How do you fellas feel about the OPTIMA battery for our conversions??
A fella at work talks about them all the time for some reason but he does not have one, only from what others have told him. He says they RAVE about them.
So whats the thought here?

Optima does not make a true deep cycle battery for house batteries. They only make a marine battery which is a not a true deep cycle.
The Optimas are just a very well marketed and expensive AGM bettery that looks nice in the engine compartment of a car/pickup. I do not believe the Optimas are really any different from a standard AGM battery, but I could be wrong.
Sam's Club sells a battery that looks the same as the Optimas and is also an AGM battery. It isn't quite as expensive and is sold under the Champion name if I remember right.
If you want Optima type batteries, try to find a local battery distributor that sells AGM batteries and you should get lot more amp hours for the money. They also should have true deep cycle batteries. Plenty of battery places sell AGMs online, but shipping will kill the deal.
I did a lot of research on house batteries when I needed a new battery for my travel trailer. I ended up with two golf cart batteries in series. The golf cart batteries lasted at least two or three times longer than the old marine battery before voltage showed they needed a charge.
AGM batteries are good if you never want to check water or if you want to place batteries in a sealed area that can't be vented.

In relying on a friend who's been in the battery business for over 45 years, he tells me that still the best battery made is Deka. In a holdover from the days I was associated with large motor yachts I'm planning on 2- Deka 8D's for the engine bank and as many 8D's as I can store for the house bank.
From what I'm told Deka has a nationwide distribution system so there's a pretty good chance of being somewhere near a Distributor if service or adjustment is needed.

Ahoy, Busnuts,
I'm not at all impressed with the four AGM batteries I have aboard my -01 Eagle. They are not old. 820 amphrs total, and I get nowhere near 410 ah at 50%. AGM stands for "Always Gonna Malinger".
I'll replace them with wet ones, probably L-16's or Deka 8d's.
Enjoy /s/ Bob |

Bob, 8Ds are really overkill for the engine batteries. Two group 31s are plenty. Group 31 is a nice size for the generator too. The generator is a place I would consider AGMs. They hold a charge for such a long time and if you canl get the generator running, you can charge the house and engine batteries and get to a plug-in or a battery store. |

I'm assuming your gen charges its own battery. I would use the smallest battery recommended by the gen manufacturer.
Then hook it up so that you can easily use the bus batteries for a starting boost if ever necessary. No sense carrying around a huge gen battery when you already have a bus full of huge batteries.
I'm going to use a lawn mower batt on my gen, but it is only 5.5 KW. |

I agree with Gus. You can always get a jump start from your toad or even a neighboring camper. It is only needed for starting the genset. Group 31 would be way overkill in my opinion.

My generator (15KW) is 12V crank and I have a belt driven alternator on the big engine (the headlamps are 12V) to keep the gen battery charged. The 24V house bank is currently Grp 31's but I plan to change them out to 8D's. The 31 is a fine battery but I want the greater capacity of the 8D's.
Like FF sez, "do it your way".

Group 31 for the engine and the generator means you can swap batteries if necessary. I have done that. The bus will not notice the difference in weight between a group 31 and a smaller battery. |

Christopher asked...."i have a 10kw wrico. what size battrey do i need...?"
Why not give Dick Wright at Wrico a call and see what he says?
