Hi Wrenches, We recently installed 12,000 Ahr of this GS battery at some cell tower sites. If the cycle life on the specs matches real life then this will be an excellent battery technology. The high-temperature operation characteristics look very good as well. A couple of things I'll say

I have 2 systems on my hill here that have the Trojan Smart carbon and the regular Trojan. They both are flooded 2V 1100 AH batteries and I see, and my clients see no difference. The both are about 6 years old. They both have the ridiculously stupid 3 ports for each 2V to water. I did not spec

Hadn't seen the spec sheet of the GS battery... thanks. It's a Carbon battery with a Carbon additive to the negative plate. Generally and this of course depends on the manufacturer when you add carbon to the neg anode (plate) it increases the cycle life, and charge acceptance of the battery. It

forgot to include the link to the GS batteries. http://www.gsbattery.com/PDFs/SLR1000-2.pdf Thank you Steve for the information on the construction of the batteries and how that affects cycle life. Cheers- Daniel Daniel Tittmann CTO Greenwired www.greenwired.com dan...@greenwired.com

Daniel, There is a big difference in the construction of these two very different batteries. The FR battery is a AGM battery with a limited amount of electrolyte and a much smaller plate than the OPZv Tubular Gel Battery. The larger plate (Tubular Plated Gel) as well as the excess Gel

I am reaching out to the group to see if there is any experience with GS batteries. Their cycle life graph is better than I have seen in any VRLA battery I have seen (see comparison below). I wanted to know if anyone on here has used them and if so have you experienced the cycle life that they
