So the battery guy at Pep Boys tested my 2 year old "3 year free replacement" Bosch battery and the printout says it tests OK and charging system is ok, he said that I probably have some sort of parasitic draw which is causing it to be dead after sitting for just 2 days, so I put it on the ammeter and there's only a 22 mAh draw and shows 14.4V when running, and the alternator diode tests fine, then I charged it for 8 hours on 10A and let it sit disconnected overnight, connected, and it won't crank the engine.
Did Pep Boys fake a test result to avoid replacing?
