Interesting to note that. Thanks Stuart.

Ya I shoulda done the charger back draw math beforehand.   ;)

I will say that I was so used to my old higher Amp charger, that
charging my group 27 with my onboard 7.2 Amp charger, seemed quite
slow. Granted this is a 100 AH battery discharged to 11.15 Volts.
Thankfully the battery charged up to 13.2 Volts overnight and charger
shows it as "100%" charged. (then again, I'm sure I shortened the life
of this battery!)

The Genius charger I bought was relatively pricey. That said, I should
have paid more for a 10 Amp or higher charger. I can see times where
one might be off grid for a few days and need to charge a battery(s)
in a relatively short period of time.

My point: consider "worst case scenario" charge time required when
sizing up your aux. battery etc. design.

Neil.
