UPG 250 amp hour agm batteries
I just finished up my residential refer install with inverter. I have two 75 amp hour batteries that will suffice for now. But this worked so great and I had so much fun with it, I started searching ...

My SIL AGMs have tubes vent hose fits over. My East Penn Deka's have valves where the fill caps would be, flush with the top. I double check they are not gassing when top charging by floating a little distilled water up there (in case any gets ingested which it should not, in theory). One bubble in a vent and I back something off.
AGMs can and do vent if over charged, or if fighting their way back from significant sulfation such as when being run flat. When my string was equalizing on float when new, I could see the stronger cells let go a bubble here and there as they cooked down to equal. That hurt lol!
