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

I just recently got one of those HF I-R guns. I will be curious to read your experiences in various battery temps.
Maybe I need a stethoscope. I definitely don't want to hear a valve make any noise. Can you explain the bubbling noise more as I have never heard any.
Optima says unlimited Amps but cap the Volts and Temps. My approach is to focus on getting Amps over Volts into my AGMs. That is more aligned with AGM mfgr specs.
Both solar controllers are MS PWM with temp comp and set for 14.4V and 14.35V, the WFCO converter/charger never does more than 13.6V and the portable has an AGM setting and ambient temp comp.
