My need for batteries are for UPS use. Hopefully only used a couple of times a year.
At this price I could add more and try to never go past 50% discharge.

It's not designed for cyclic use, so unless you only cycle to 70% or less DOD (depth of discharge) you will kill that type of battery in less than one year. Any lead acid wet cell or AGM designed for off grid or cyclic use will have a manufacturer's datasheet rating its Ah storage capacity at 1 hour/2 hour/8 hour/20 hour discharge rates. Re: the Aquion batteries mentioned above, they're much more expensive and are HUGE, but they supposedly will have 80% of their storage capacity and life remaining after 4000 cycles to 50% depth of discharge. It's the cycle life that separates them from even the best very expensive SLA AGM batteries.

The 6V's we buy are 135 AH and we get fewer cells going bad over 2-3 years... When you have 100 cells at a site, you are going to have failures... (1.2V cells)... Found it was cheaper replacing 3 cell batteries than 6 cell batteries... On 10/03/2016 12:09 PM, SmarterBroadband wrote: 120AH for $83?

For that price diff you can literally throw away batteries each year... On 10/01/2016 11:42 AM, Lewis Bergman wrote: That seems expensive for the AH. They sound like they recover better from deep discharge. The last time I bought 75AH batteries they were ~$200 each. so for somewhere less than half the money you get close to the same AH and they added bonus of destroying the planet.
