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 ...

I would not even ATTEMPT to manage a VRB without an amp hour meter. A real one, connected exclusively to battery negative. Use kWh to establish a Charge Efficiency Ratio percentile, then use ampere hours returned as well as algorithm percentage I at value E.
Now most will moan, cross an amp hour meter off the list, then go on to complain how unnecessary all this is. The entire 5 minutes of work it takes to set it all up. It does not take a genius to set this up. But it takes a modicum of EFFORT. Oh gee look -14 amp hours. Wonder if my battery is charged. yeah "Take the cube of voltage and divide it by estimated ampere hours times two after a two hour wait and this will get you in the ballpark". Just do not blame your battery...
Already know that after 3 days (72hrs) of storage, after my Amp meter reads a .75 ah reading per hour, that 12.88V is what I expect to see. It's what it did the first time I recharged full after I used it a little bit and took 8 or 10 amp/hrs out of it in test.
We will see what it takes to get it back there. Put it on the charger at 3:40 PM pacific time, battery was taking 7.7 amps after it quickly settled in.
Taking log notes, perhaps until midnight, probably less.
Forgot the DMM at the trailer, will get it tomorrow. Battery was reading 12.84V on Saturday around 6 pm when I disconnected.
Another vet bill for another sick cat coming up today @ 4:45 PM.
