Not exactly sure what my mowing time would be (minus dancing with the extension cord, that is) - but definitely no more than 30 min.

"the discharge times aren't that different."

True, but we also don't yet know the current draw of the mower's motor. The capacity test was with a 4A draw. That's a big wild card.

Also, if we do exceed the run time of the battery with the lower capacity, the mower will probably murder it before it does an auto shut-off.

I've murdered a few batteries in the forkenswift this way. The healthy batteries will continue to work after the weak one has given up the ghost, so it masks the damage you're doing -- unless you actively monitor the voltage of the weakest batt(s).

Anyway, we'll have our answer next week!
