Ahaha, nice work

Criminy, never seen ones that bad hold a charge! If you stuck a 'scope on the power lines I reckon you'd see a hell of a ripple up.

The only other real value of interest to the regular human being is ESR - Equivalent Series Resistance. There's no down-side to getting lower ESR ones than rated except possible pocket damage - ESR goes down price goes up. If you can satisfy the ratings out of Jaycar's "Low ESR" range I'd just go for those.
