Lots of information.. Here is what I have found.
Flooded wet cells for the most part are standard.
AGM, not so much
Where as most AGM's need to be treated much like Flooded cells, save for perhaps a slightly different peak voltage... At least one company recommends an initial charger rate many times faster than what is normal for other battery types. Other companies may suggest a higher, or lower voltage.
SO, This is my recommendation.
One: You need a FULLY PROGRAMMABLE charger (Such as, but clearly not limited to, the charger module in a Xantrex Prosine 2.0)
Two: You need to pay a visit to the battery maker's web page and
Three: DOWNLOAD or copy and paste the data you find there on YOUR batteries to a printable document so you can hold it in one hand while you program with the other based upon it.
