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 ...

OK, just got off the phone with East Penn. Obviously a very young, highly strung guy on the other end of the phone.
First off, plates are made of pure, virgin lead, from Canada, eh! Politics involved with even getting or smelting pure lead in the USA, more jobs exported to Canada. Plates are 99.85% pure lead, balance is a little bit of tin, and a little bit of calcium to stiffen/harden up the plates a bit.
SG is 1.300 on this battery. That means storing it in desert heat is bad juju for longevity of life of this battery. It's really designed to sit in a temp regulated cell phone tower environment.
Charge voltage, without doing an equalize charge and causing offgassing is 13.50V plus or minus .02V. It takes almost a full week, supposedly, to fully charge this battery.
My date code on the lip of the top case is 4301F, what that tells me is that in 2014, on the 301st day of the year, this battery was filled. The 301st day was Oct 28th, 2014. This battery is not even 10 months old and has probably only seen 8 or 9 months of use. Deka Penn, builds and fills these batteries to order for Telecom companies.
This battery should NEVER be stored at under 12.6V, and always be charged up in full ASAP with a full charge when done with being used in our applications.
Lead plate thickness is proprietary. It has a lot of lead in it, hence the weight of the battery, assumed to be very thick plates to get 10 years life out of it. It is designed as an acid rich battery, not acid starved.
Battery is designed to last 10 years, DEKA warranties them for 7 years to the Telecom companies. They are basically built to spec for Verizon and AT&T. It's a $600 list price battery. I don't think I did so bad for $125 if it wasn't abused by the Telcos.
12.88 V OCV is a very good number, so I am told, for the standing voltage.
Hope this helps anyone else, if I get 3 or 4 years out of it or more, for $125 and 158 Ah rating, I'll be a very happy camper.
