The cheese grater size tester is like stress testing while you're sitting in a recliner chair. WORSE THAN USELESS
The load amperage needs to be ADJUSTED to ½ CCA amperage then held for 15 seconds.
I would laugh at the handheld cheesegrater 100 amp fixed load. But error by 350 amps too few for a group 65 makes me wince instead of chuckle. Parts store testing is a farce.
