Does DEKA make a good UPS battery?

That 13.5v maximum is certainly in a different ball park.

What kind of chargers do these telecom batteries have attached to them?

What is the expected service, like a power outage, What then is the individual load on each battery, and for how long. How many of these do they stuff on the mountain top?

I guess that if they say it takes a full week to charge at 13.5v, they are not expecting frequent power outages.

Anyway for 125$, I think I'd just beat the snot out of the battery using it as a Dang well pleased for maximum convenience. Hard to learn anything if it is treated like a porcelain baby.

I wonder if you did take it to 50%, or less, how long it would max out the Megawatt at 30 amps when set to 13.5v before hooking it up.

I say cycle it to 50%, set the Megawatt to 14.4v and let er rip. If the sides bulge out alarmingly or you hear/smell the vent open, then the adamantly spouted 13.5v maximum perhaps has more merit.

I am guessing here, but in the battery specs, they place heavy emphasis on an 8 hour discharge rate. Which to me would indicate they feel they have enough service support and reaction time and spares to have the site up again and on the grid in 8 hours or less. They also talk about full depletion to 11.7V. So these batteries are spec'd to be true emergency batteries, give their all, in 8 hours if needed, and life of battery be shot, or severely shortened? The telco's expect that to rarely if ever happen in the life time of a battery, but I suspect that's the engineering spec the telco's are after, just has to do this routine 1x, 2x or maybe 3x in it's lifetime, and it's served it's purpose.

Using it for RV purposes is completely out of it's realm for design purposes.

I'd be really interested in hearing Wizard's observations if he's tried these a few time, about how they last, lifetime wise in RV conditions.

I know I have a fairly new battery, the question is, can I avoid abusing it and impacting it's RV life on my Travel Trailer.
