I need to replace the lead acid batteries that came with my Hallmark truck camper. I want to use AGM. Can anyone provide a recommendation. I have solar on the camper if that matters.

I picked up two AGMs at Sam's Club for my Hallmark last year. No problems. Solar is not an issue as i am sure you have a controller between your panels and the batteries. Makes life much simpler with no need to periodically add water to the cells.

Type of Tiedowns used: Torklift with Fastguns
Truck and Camper Setup: The plan will utilize a 3500 GMC with a 11 or 12' TC with a full compliment of Torklift hitch components and tie downs. Stable loads if needed will be installed.

Take a look at Mikes site, Truck Camper Adventure. Scroll down to the bottom for an excellent article on care and maintenance of AGM battery's.

Actually, if your converter is working properly, the maintenance on a flooded cell (I have 2, Group 31's, is not much more than a twice yearly water check. and insuring the cableing is tight.

The only advantage to a sealed agm is no venting required but my battery box was already vented. Draw down is the same (no less than 50% total charge and charge rates are the same as well. Only advantage is no venting and no water checks, both of which are easy for me.

If I was to go to a different battery, it would be a Lithium or Lithium/Iron Oxide battery. Half the weight of any conventional battery, ability to install anywhere, even up side down and the ability to discharge to almost no capacity remaining without damage.

Problem is, they are very expensive, typically around 800 bucks for a Group 31 equal.

If you have the wallet, a Lithium or Lithium/Iron oxide is the way to fly.

If I was flush, I'd have a pair.
