On my last two visits to the dealer with my 1999 TL, both times my invoice has been flagged with a "Red" condition on the battery. Most recently, the battery box on the form showed "Factory Cold Cranking Amps 550," "Actual Cold Cranking Amps 550." We've had some pretty cold weather here in the Mid Atlantic these past couple of weeks, and the car continues to crank and start without a problem. It is outside, and takes no longer to start that my garaged 2015 RLX. Anyone know why a battery delivering the specification amount of CCA, installed in a car without any apparent starting circuit problems would be flagged "Red" for replace?
