I went to Advance Auto Parts to get some brake parts a few days ago, and I got my battery checked (always good to know how it's surviving), but the terminals were too messy/corroded and I needed to clean them off for a good reading.
I came back yesterday, got my alternator checked, and it's great! However, something was bugging me . . . in a very good/odd way.
I believe my battery has 550 CCA (Cold cranking amps), but when we tested it it had 1100 CCA
The person that checked my battery was soooooo confused but didn't think there was an error. She even told me my battery was superman.
Any idea how my 550 CCA battery could possibly have 1100 CCA? I rather like it, but it seems a little off.
