AGM Battery Replacement

I have a 2011 Greyhawk with a single 12 volt house battery that is too difficult to maintain due to the poorly designed pull out drawer, almost impossible to readily check or add water, plus it's getting older.
Plan to replace it with a maintenance free AGM battery. Any issues with this plan? Does the charging system have to be changed? Thanks.

AGM Battery

You can replace your wet cell battery with an AGM (Absorbed Glass Mat) battery without any changes to your unit. As with any vehicle, the charging system must be in good shape. An alternator is a battery MAINTAINER, not a charger. Replaced our M/C battery this year with an AGM, and it works great. The difference is only the design on the innerds that holds the acid.

According to what I've read (cuz I'm getting ready to go AGM) is that the AGMs should be charged at a slightly lower amperage. My three stage inverter is set up correctly so, no worries for me. You may want to do some research on the particular AGM battery you are looking at, then compare with your inverter charge rates. I found the inverter information in my packet of literature from the dealer. Good luck!

The PROGRESSIVE converters that JAYCO is now using work on both AGM and wet cell.
