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 http://www.eastpennmanufacturing.com/wp-content/uploads/Deka-Commercial-Batteries-Flyer-0010.pdf (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 ?
