Does DEKA make a good UPS battery?
I took a trip yesterday down near San Diego, it was twofold. One was to replace my free Trojan T-1275 that was a golf cart reject already when I got it with a pig of a 105# UPS 145ah AGM battery from ...

Once my NorthStar AGM gets to 14.46v, it takes about 4 hours for amps to taper to 0.5% of capacity. Longer if it has been low and slow recharged cycle after cycle for 5 or more cycles, or cycled deeper than 50%.
I've seen it take 10 hours after reaching 14.46v, after 7 cycles to 50% or deeper and solar only low and slow, for amps to taper to 0.5% of capacity.
Goosing voltage to 14.46 and checking amperage to hold it, is my measuring stick as to full.
Voltage held under discharge/AH removed is my barometer as to when that high amp recharge is required. The time it takes for amps to taper to 0.5% of capacity at Absorption voltage is highly variable depending on depth of discharge and the amount of accumulated cycles since it last saw a high amp recharge.
My Meanwell is the goosing tool. My vehicles voltage regulator allows upto 14.9v, but will also choose a 13.7v maximum arbitrarily, sometimes it seems to like 14.1v instead. I've not accumulated many miles lately.
So it goes. I do not even have a house battery at present. The NS AGM is both engine and house battery, and I am questioning my need for a house battery at all, this time of year.
The screwy31 still has not shorted a cell working to power a TV and fan and some lights in my workshop. It too gets the Meanwell Treatment, but no Hydrometer loving. I just keep raising MW voltage to produce 5.5 amps and try to keep it under 25 amps initially. Somewhere at around 15.4 volts the amps no longer taper, but start increasing, and back to the concrete floor it goes for another 10 day long discharge. Over 500 cycles on it now.
