Or does the machine knows the battery is under warranty so it fudges the results? :-) The background:- 99 Camry; I noticed little bit weak cranking. Doing some testing showed it had no load voltage of 12.2V (should be 12.6 or above) and dipped down to 8.9V (should have stayed over 9.6V). The alternator is fine (13.7V - 14.4V)and car runs mostly on the highway (30 miles one way). This is OEM Toyota battery replaced in 1/2012, so it has still some warranty left. Just for the grins, I took it back to the dealer. His machine tests it and it passes the battery! The printout given to me shows RESULTS: - GOOD - RECHARGE RATED CCA 575 MEASURED CCA 612 MEASURED VOLTS 12.32 DEGREES F 62 STATE OF CHARGE (SOC) 75% STATE OF HEALTH (SOH) HIGH Anybody wants to bet that if I were to take this battery to Autozone or Advance, they *will* fail it and sell me a new one?
