Two T105s at 12V should give you approx 220 Ah. A single 12V G31 usually gives you around 100-105 Ah.

I understand your question to be about comparing capacity of ONE G31 to TWO T-105s.

So no, 100 Ah for a single G31 is less than half of 220 Ah with 2x 6V T-105s wired to provide 12V.

Usable Ah -- while drawing down to no less than 50% state of charge (SOC) -- would be more like 50 versus 110, still less than half.

Re: AGM Fire fly Battery

I wait for the 6 Volts then hope I can get one to two years out of my T 105s
