Charging antimony-free VRLA batteries without float
Here is a proposed much lower float current method to charge non-antimony batteries. Supposedly better than traditional float. Low current float for AGM

As a practical matter, my Deka AGM batteries are 5 years old, and they have been on charge 24/7 when we are not on the road. My converter is a Xantrex that puts out a float of 13.6 volts. The batteries seem to be performing fine.
So far so good. 13.6 is barely over the specific float voltage spec I got from Deka, and within the float range they allow, I think.
I need to calibrate my volt meters. They agree with each other to within a few hundredths, but the volt meter in my charger is sometimes many tenths off one way or the other, and not by a constant amount.

There you go Obssessive-Compulsive-Disorder(OCD) on Volts again! :)
Set your chargers for 14.4V temp comp and calibrate your Amp meters!
Take a deep breath, let it out slowly while saying Amps, Amps....
How many AGM owners with 5-10yr old batteries it going to take?
MY solar two stage MS SS-10PWM doesn't even have a float stage! It simply holds 14.4V temp comp and tapers Amps so low that the battery reaches stasis. Rinse and repeat every day. This is the system that runs my 12V fridge and freezer. We're talking about my beer and ice cream, man!
Think Amps! ;)
