Battery recommendations

I'm curious ... why do you think that you were running your previous flooded chassis battery partly discharged too much? I'm assuming that our flooded chassis battery is getting fully charged by the alternator between campsites - but we do change campsites often on RV trips.

For those of us fortunate enough to be able to store our Class C RV's at home, I agree on keeping it kindof ready for use as a get-away vehicle at all times.

Took a look at the log data I had. I’ve been running 84-month batteries in several vehicles and never paid much attention to them. Would replace them at 84 months with no issues. The moho chassis battery lasted only 64 months and had to use the house battery emergency start when it failed.

One car did have a battery issue but it turned out the alternator was failing.

Have had the chassis battery connected for a while when working on it and measuring 12.44V currently. Fully charged I remember measuring 12.7V where fully charged AGM should be 12.8V+. The electric steps + other drains are likely drawing enough current to pull the voltage down 0.1V. I haven’t measured the actual current draw.

Charging chassis battery now until I disconnect it until the next trip.

I have a pair of 6V Duracell AGM golf car batteries from Sams Club supporting our house operations for over 4 years now. They are still awesome. I never deal with acid boil-overs or corroded terminals. I have not touched them in the 4 year period except to manually charge them when usage is high or when in storage. With easy access terminals, even that is a breeze.


I wonder how a 12V AGM battery would do in supporting the chassis.

I've had an AGM battery in my 4X4 pickup for engine starting about a couple of years now. No problems so far - but it's not a "deep cycle" AGM - it's an AGM intended for starting and chassis use.

I almost put an AGM starting battery under the hood in our Class C a few weeks ago, but opted instead to default to the Dark Side by installing a heavy duty liquid acid battery there - just to save a few bucks. :(

The 2 12-volt AGM house batteries we have are still doing well at 8 years. They were made by Odyssey for Sears and are identical to the Odyssey Extreme which is rated for 400 cycles at 80% discharge. Usually discharged them just 30% so they still have cycles left. I am getting a better sense of how many amp hours are needed to recharge to full using a solar suitcase with a charge controller.
May replace after this season if we decide to do some cold weather dry camping.

Also carry an extra X2 power AGM for misc use dry camping.
The chassis battery is also an X2Power AGM. It powers the electric steps as well as the chassis. I am finding I have to recharge periodically to keep it topped up. Running the previous flooded battery partly discharged killed it early before it’s rated 7 years.

Why all the AGM? The southern half of the Cascadia Subduction Zone is well overdue for a megaquake so each time we go out near the vulnerable areas we are prepared to be cut off.

We also got around eight years on our first set of 2 12V AGM house batteries before we replaced them "just in case".

I'm a fan of Deka batteries. They are long lasting and dependable.

I put in two 6V GC batteries that would fit the compartment for less than $150 each on the current camper. Just like I have done on other new to me campers. I have never had a DC issue.

The first ones were nine years old and getting weak. The rest were replaced just because….

If the charger (converter) is a three stage charger. I have not had any problems. Just check the water level twice a year.

I like cheap & KISS….
