AGM Adventures- Update
Updated 31 Jan 17 Initial results. I will re-test the AGM after it does one deep cycle to confirm these results. EDIT completed 6 Oct Test was to put the test battery as the only battery run...

Methinks a performance characteristic of the battery might be getting misinterpreted. Where the AGM stands out is under heavy CCA type loading. Compare a 100 amp hour flooded to a 100 amp hour AGM using a 100 ampere load and watch voltage/time. Study the difference in electrolysis (gassing) between a calcium/calcium flooded battery and standard lead antimony. Water loss is dea.atically reduced and the C/C battery does not even have recombinant capabilities. Again I will point this out: AGM batteries are used successfully in underhood applications where temperatures soar in excess of 150F. I know of no automotive charging system that comes even close to compensation recommendations. You have to really try to force an AGM to vent. Absurdly high voltage coupled with high internal temperature. The way my Lifeline is living I would be quite surprised if it didn't have a useful lifespan of 15+ years.
