I bought my son in law one of the larger ones from Jaycar, but had no reason
to look at its amp/hr rating, as its primary purpose is short duration high amperage use, not powering devices.
However, as the claims on the box seemed to be over optimistic, we stuck a flat battery into his Mazda 2.5lt turbo diesel, and got seven easy starts and
a struggling eighth one. Pretty damn good, I thought.
