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

At 13.6 what is the current, the amperage aggregate over a day or a month? If you want to fine tune, use an adjustable regulated power supply for constant loads. That and a verified accurate kWh meter is the least expensive way I can think of to establish long term float "precise" reliability.
