Hey thats cool!! I wanted to do a load test on my GC2 batteries when brand new and then throughout their life. Plan was to do something like a 20a load and monitor voltage drop on a fully charged battery. That works well (not at fully charged) for lithium batteries found in RC toys. Not sure if its a good test for a flooded lead battery though.

I bought one of those at least 5 years ago, maybe longer.

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.
