Mother in law brought her 04 PT Cruiser to Firestone (I know that's another issue) and they said she needs a new battery. Current battery - mopar oem replacement -was replaced 3 years ago when she purchased vehicle at Chrysler dealership. Went to Advanced Auto tonight and here are the results: Temp: 43f Voltage: 12.54v Measure CCA: 570 cca Cranking voltage from starter: 10.72v - voltage during start-up went from over 12 to right around 9v which stuck out to me Charging was solid at 14.2 with high beams, blower motor and some Lights on. What do you guys think? I'm leaning toward telling her to get the best Costco battery she can as preventative care going into our cold winter.
