Wow, that thing is tiny. No spark issues? TBH, I don't really know the low-level electrical details of how engine ignition systems work, but I was under the impression that basically an engine can't generally run very well on its alternator alone; that the required juice to give a full-power spark comes from the battery (in rapid intermittent bursts as the plug fires), and the relatively-constant output of the alternator is topping off the battery between those bursts. Which is why really tiny batteries always worry me a little, re: potential to lose some of your full spark amperage. I could be way off-base, though!
