Field test report of new AGM design
Been field-testing an interesting new 6v GC2 AGM design from Fullriver. Now I can talk about it.
The capacity is a typical 220 ah @C/20 but they weigh 83 lbs. Run them down to 0% SOC then recharge to 100%, roughly following BCI standards but at a slightly lower discharge rate of C/5 to C/8, got 1022 charge-discharge cycles at 100% DOD. I am very confident that their published numbers are conservative.
This is not earth-shattering, but it certainly is a cost-effective incremental improvement for AGM's with well over 1,000 cycles at 100% DOD.
More importantly to me, a typical 25% average daily DOD translates to 3,500 cycles to get to the operating life of 10 years that I see with Concorde at a slightly lower average DOD. From what I can see, these will sell for about 10% more.
I always have more questions than answers. That's the nature of life.
