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.
