House Batteries
I have a 2018 GT5 31R5. I am looking for advice on replacing the two house batteries. The current batteries are original lead acid ones that came with it. I am interested in using an AGM type. I would like info on size, amps ect. Need ones that will be charged by the current charging system. Any advice would be appreciated.

Batteries
Hello, here's a good thread about changing to agm batteries in a similar rv like you own. https://www.forestriverforums.com/fo...es-240385.html I ended up going with a group 29 Everstart marine battery from Walmart. We don't boondock that much, but have found these batteries perform really well. Hope this helps

All of the info should be on the label on top of the battery. Take that information, make a picture, to any auto parts store or battery store, etc.
They will be able to supply you with the correct size and amp hour rating in the AGM format.

Why throw away good batteries? Wait till they die and then change them out . Mine lasted 7 years.
I keep the MH on charge all the time and check the water level every month. We don't boondock all that much so the house batts hardly get used.

for the price of a AGM upgrade...
you could look at a battery that can store more energy
A TRUE deep cycle ... that can be discharged more. something like a Trojan Motive
True deep cycles are designed not be used for starter motors that require a heavy initial rush of current...
If you want to .. add a automatic watering system
but I don't have a problem in checking the water level ,
I keep a bottle of distilled water in the trailer

That was the conundrum I ran into with my Georgetown. Technically the house batteries are for the house but they also start the onboard generator. In a pinch you can press and hold the Battery Boost switch and that connects the house batteries in parallel with the chassis battery to start the motorhome engine, if the chassis battery is dead.
Do I take the chance that two house batteries could always start the generator? Probably they could. But cranking that big old V10? That might be iffy. That's why I went with Dual Purpose batteries again, although AGM this time.

The cheapest and most storage comes from gc2 batteries. However, they are taller.
AGM are a special battery for vehicles likely to roll over. Planes, boats, atv’s, motorcycles. The big deal with them is no maintenance, checking levels. Also they can go inside a vehicle. No drain needed normally.
However they are more expensive, last about 50% as long, less ability to recover from abuse.
My truck uses them. Almost $600 for a set last week. Gc2’s are about $200.
Got to measure your space carefully.
Now, lithium would be my choice! The DW has discovered Harvest Host. She loves the free camping at a winery or farm. The Moab desert camping! Never thought I would care about sleeping out!

in my boat I have a house battery that won't crank the engine by itself
I can connect it in parallel to the starting battery using the 1-2 -both -Off switch
the house adds some charge to the starting battery .. takes a few minutes but it will then start. As long as the starting battery can accept some charge.
you can do the same on a RV using jumper leads if starting battery is low
be patient and let some charge go into the starting battery

Thanks everyone for their input. I had them tested and they are performing as expected so I will hold off.

It’s worth noting, this being a motorhome RV subforum, and as already mentioned in post #6, that most motorhomes already have a switch/relay that connects the house and chassis batteries together for emergency situations. No need to use jumper leads.

Not sure why you check water level monthly? If your charger is a smart - 4 state charger it will not boil the water so there is no water loss?
