AGM bank needed....Trojan, Rolls, Concord or Full River?

Postby flyinghigh on Sun Mar 22, 2015 8:32 pm

I have a retired friend looking to purchase a AGM bank of approx 800 AH comprised of (4) 6v batteries. Given his age and living location, AGM is what he wants. The bank is just for peace of mind as he doesn't have many years left and is hoping this will be the last bank he buys. It sits and gets charged when it drops to 75% of capacity which happens 1-2 times per year.

It seems like the thickness of the plates is the determining factor for when a "standby" bank actually fails. We have been looking for plate specs on the AGMs, but while they publish them for flooded, they all just say "thick plate".

We have it narrowed down to 4 manufactures that all make a similar offering:

1. Concord Sunsaver in L16 case. The original...only a 1 year warranty. 405AH
2. Trojan has a new reliant series AGM which they claim is the only "true" deep cycle AGM available. 2 year warranty with lowest AH in the L16 case...370AH
3. Rolls has a L16 version with a 5 year warranty and 415 AH
4. Full River has a L16 version that looks just like the Rolls and has same 415 AH and the longest warranty...7 years and the lowest price by several hundred $$$ on the set.

Any thoughts?

Hello flying high.
While pursuing the threads I came upon your post from last year. I am in the market for a larger bank, possibly some AGMs. Currently we have a small bank of Concord Sunsavers, and I am trying to figure out what I'll go with this time.
Did you and your friend arrive at a decision? What was the determining factor?

Thanks.

Steve
