Replaced the 5-6 year old battery in the 2010 Acura RDX

Posted By on February 4, 2023

After 5 or 6 years, a car batteries no matter their indicated warranties, lose some of their cold cranking amps (CCA). If I were a “maintenance-focused only kind of guy,” I’d probably just replace batteries every 5 years rather than waiting forthem to fail. BUT … as usual … I wait until the winter when it is near zero degrees!

Since it is early February, it is of course cold. Brenda’s 2010 Acura RDX has been sitting for a month due to Brenda’s hip replacement (in the garage at least) and it failed to start this past week. After a quick charge and test, it started the car, but would not deliver the promised 490 CCA needed; the testing registered only 230 CCA after an overnight charge.

So … it is time for a new battery … the story of my life.
