Does DEKA make a good UPS battery?

What was the OCV when you got the battery?

I think an AGM battery that size for that price, is a steal.

You will certainly notice different numbers on you Megawatt's ammeter.

My Northstar AGM is an AMP whore, it just gobbles up everything my charging sources can muster until the mid to upper 80% state of charge range. That Lifeline GPL-31Xt battery I had for a project was even more impressive in terms of voltage held under load and its ability to accept HUGE recharging currents.

My Northstar is both my Engine starting battery and house battery at the moment, and it seems to be Okay with that. I can plug in and not cycle it overnight, but, well lately, I am anyway. The voltages it holds for the AH removed, still impresses me at 20 months of age and ~ 120 deep cycles, and even with 55AH removed from a 91AH battery, it easily cranks my v8 engine.

I am debating the necessity of a house battery, at least in summertime.

Open Circuit Voltage? I need to get the DCM out of the TT to measure it. I have not done much with it yet, still sitting in the trunk of the sedan.

I need to use the old battery first to tune down from 14.8V charging to 14.4V both on the MegaWatt 30 and the charge controller for the solar panel. I do understand how power hungry AGM's are at sucking huge amps when first recharging. Which means that AGM battery in the Touareg and it's alternator voltage already at 14.3 with 175 amp hour capacity, with some jumper cables would give this battery a nice blast of amps, at the proper voltage 14.3V, if need be.

I might need to work a deal with mexicowanderer to build me a Frankenzapper 10 spin pot whizzbanger charger for this out of a 36 amp Megawhat, with gauges on it for Volts and watts, when he needs a newer cell phone.
