Time For a New Battery?
It dawned upon me last week that my battery reached the 5 year mark (Original ACDelco 6YR-90, 12/2011, that came with vehicle - 2012, 1LT, 4cyl).
Decided to check it out. Clean and snug. Voltage stated 12.3v first thing in morning, turned lights on for about 20 seconds, it dropped to 11.4v. With car running, 14.7v. After I went around the block, car off, battery measured 12.6v sitting. What bothered me is it dropped to 9.5v minimum momentarily when first starting (starter engaged), and that is a flag to me.
Took it to AZ where they determined, 'it's 95% charged A OK'. So, I tried AA, and they determined the battery CCA to be 486, when the minimum of the battery spec is 590 (CCA roughly 82% of minimum). They didn't know what that meant :-) The outside temp was 70 degrees, and I'm assuming the CCA to be at 0 degrees as reflected on their tester. Don't see a lot of 0 degrees in Texas.
The battery has started the vehicle just fine when it was 18 degrees out recently, so it seems to be alright. Anything I should be concerned about based on the Info provided?
