Don't flooded have a slightly better power output?
I think the AGM are hands-down winners because of the maintenance
issues. We have solar sites that we don't visit for over a year
sometimes. They are on AGM.

However, they are classified as hazardous materials due to the amount
of liquid electrolyte and that may affect zoning and insurance (if any
one asks).
I would not use a lead acid flooded cell unless it was in a temp
controlled environment.
If you have 120 batts to replace, sounds like they might be
outdoors. I would use AGM.

*Subject:* [AFMUG] Deka 7T31 non-AGM batteries
Guys,
We have always used the Optima D31M AGM batteries (just because).
Well…. It’s that time… time to replace 90% of them, and looking for
alternatives. Having to buy 120+ batteries… cost becomes something to
at least look at.
My local supplier says that FPL (Florida Power & Light – aka Florida
Flicker and Flash) uses the Deka 7T31 non-AGM batteries (Lead Acid)
and they are a lot cheaper (waiting on price – I found them quickly
for $ 100 each). They are a 100ah batteries. Here is the spec
otherwise

(minus the ah rating which I got from Deka over the phone).
Does lead acid have distinct disadvantages from AGM? Also, anybody
using Li-Ion yet for a tower battery bank? Probably not cost-effective ?
