How to test auxiliary batteries for amperage?
I need a way to test a pair of six volt Trojan 105's wired in series and setting in my shop. Has anyone a method of amp testing batteries that are on the bench? I can't think of anything 12 volt tha...

Matt is right.
Full load testing means achieving 50% of CCA for 15-seconds while monitoring voltage. A capacity test will tell you if the battery is damaged. But it takes a lot longer and I deal with an OP's inquiry if it is valid. You wanted to know about carbon pile load testing.
Handheld CHEESE GRATER load testers are great for lawn and garden tractor size batteries. Try to test and regular RV battery and it would be tantamount to giving an Olympic weightlifter a 25-pound barbell and seeing if he could lift it.
Foolish me. If I was selling batteries like those, I would reveal to potential buyers exactly what happened and that the batteries were tested and proven good. But that's me.
Slap a STRONG 12-volt muffin fan onto the Harbor Freight 500-amp variable load tester and it turns mediocre into decent.
