If you took it to the buyer and have not get a call complaint you most likey got er dun.
If you get a call I would probably take another battery and a set of jumper cables.
(I've got all kinds of electrical testers but find that I usually just start jumpering things out using a good HEAVY duty set of jumper cables,
BUT before last winter I bought one of the jump and start battery packs on sale with free shipping from tooltopia
this one
Clore
Jump-N-Carry 1700 Peak Amp 12 Volt Jump Starter
and it's really user friendly being portable for starting/checking small engines that does not even have a on board battery or has a old weak battery, large tractors or eq that have not been started in awhile, lots easier than using jumper cables from a vec's battery.
and especially in cold weather using as helper boost starter. Weighs about 25-30lbs and has a built in charger.
Really user friendly for checking things such as you describe also.
But intermittent/erratic crank start issues are not easy to isolate sometimes, no problems at the time you are testing, but when at the new owner the problems re-surfaces quite often.
I've not had any experience with the smaller more portable lighter weight battery booster packs that will charge from a USB connection.
