Amazing these new batteries.
Starter motor works on 22 amps? WOW!
That's a big improvement over the years also.
(You did disconnect the RV battery to do the test to simulate a dead battery, correct?)
No I did not disconnect the RV battery. BUT, before I connected the jumper, I tried to start the vehicle. Turning the ignition on, no dash lights were lit, there was no enough voltage for anything to turn on. I didn't even bother to check the voltage on the battery. But I hooked up the charger (very compact and relatively light) the engine cranked right away abd the engine started within about 2 seconds! That was impressive.
I doubt the started motor was just pulling 22 amps, that's low for a starter. The figure of 22000 amp-hours should be the capacity of the battery for putting out 22 amps for 1 hour, or 44 amps for 30 minutes, or 1 amp for 22 hours. It does not mean it is limited to 22 amps.
