I'd gotten the free battery test at the tire dealer's last week, and they'd told me my battery was weak.
Not being the trusting kind, I went to Advance Auto today - and their check said my battery was "good". Is it safe to assume that the tire dealer wasn't telling the truth, or are there legitimate reasons why their test could have said my battery was weak?
Also, the pr Voltage: 12.74 CCA: 502 Rated: 600
How can the device know the rated amps? Or was it that the guy read it off my battery and entered that number into the device? (It's the original Delco, if that matters, on a 2002 Century, with a low number of starts.) Thanks.
