Has anybody on this list ever used Thermoil? http://thermoil.com/
My dad has a Jeep that sits for months at a time while they travel in the winter. He used Thermoil in the battery when it was new, and it's still going strong after more than ten years. He also put it in the house batteries in his motorhome, and they still have most of their capacity after 12 years. I'm not sure if it's related to the use of Thermoil, but he says that the battery terminals do not show signs of corrosion either. It's about time to replace my 48V battery bank, and I'd sure like to hear what you guys think about this. Comments from battery manufacturers would also be appreciated. See ya!

I see on the list that wrenches are talking about AGM, but I can't imagine using them when considering the size of your system. Their (Surrette) service has been A++. I have several systems that are now over 10 years old and show very little sign of aging. I love their dual containment system.

Do you know if Deka has more than one manufacturing plant? My Deka representative did respond. Perhaps I could have expressed this better: the response was "they are out of warranty". I knew that. However, due to the number of Deka battery failures we were experiencing, I would have expected something more than "no warranty". They did replace one 8D that failed at 13 months. Thanks Deka. During the last few years that we sold and installed the Deka AGM's, we also sold Lifeline, Sun Xtender, Trojan, Optima and FullRiver. We sold 3 times as many Lifeline as we did Deka. Zero failures form any other brand. I have a customer coming in today that has 2 8D AGM's. I installed these 11 months ago. His complaint is that the voltage will drop to 11.5 within 5 hours of use. I'll let you know what I find.

I have a set of 8D AGM's in my own system. The local factory warehouse is responsive to our needs.

The company will not respond to the problems so we will never sell another Deka or MK (made by Deka) AGM battery.

The Absolyte GP (GNB 100G17) vs the Deka Unigy II (AVR95-19). Both have similar reported Lifecycle curves, 1200-1300 cycles at 80% DOD. Any field experience to share? The Deka seems better on paper, larger AH capacity per dollar quoted from my distributor.
