AGM Battery Suggestions - Good, Better, Best?
Hi, Any suggestions on 12V AGM Batteries? I'm looking for Good, Better & Best battery choices. Any suggestions would be appreciated. Thanks, Ken

How do you plan to charge them? Your converter won't do the job right and that is a lot of money to spend and not protect them by proper charging.
The nominal and float voltages for AGM are about .4 V higher than a wet cell type. Nominal=12.9 to 13; float 13.2 to 13.4.
You can't really make that statement without knowing what voltages his specific converter applies to the batteries.
AGMs tend to charge a bit faster but a wet cell charging voltage might leave them around 95% instead of 100. That's not a big deal as AGM chemistry does not suffer from sulphation much and never charging above 95% really does no harm.
In my unit, the generator and shore power charging isn't too high but when the engine is fired up going down the road, the charging voltage is more than enough to bring them to to totally full.
It is nice to know what is going on with the charging but normally NOT necessary to fret over the relatively minor difference.
