[RE-wrenches] Sealed Batteries

[tom jacoby]

Hello,
SELF is considering new battery options for our off-grid projects (primarily health centers in Africa at this time). For the purpose of this post, assume an average 48V 500Ah battery bank. We prefer sealed batteries because maintenance/watering is not always available. 

Does anyone have any data or experience for with the following batteries? (To date we have been using the Deka MKs). Any real-world data you have on cycle life vs. depth of discharge would be great.

1. Universal Power Group (UPG) AGMs (i.e. UB 8D)

2. Power Battery PSG/AG product line (i.e. PSG-12255FT)

3. Lifeline (i.e. 8D or L16)4. Surrette AGMs

I am welcome to other suggestions as well.


Thanks in advance,

Tommy Jacoby
