Today I played musical chairs with car batteries starting with a Sam’s Club Duracell battery (8/21date code), rotating between my 2006 Corolla LE, my diesel Kubota tractor, a farm implement (12 Volt Fimco 15-gallon sprayer), and the battery to return to Sam’s to get a refund of my $18 core charge. Allow me to explain.
Battery in the Corolla was another Duracell date code 4/18 made by East Penn, I think I installed it in June 2018. Rated 625 CCA but after 3 years 3 months of service still measures 100% good and 705 CCA. East Penn rules as far as I am concerned.
That one I will put in the Kubota. It takes the same group 35 car battery as the Corolla. The brand new Duracell date code 8/21 to go in the Corolla is rated 640 CCA but it measures a whopping 820 CCA.
Now I put the battery removed from the Corolla into the Kubota diesel and swap out what was in there: a Costco Interstate date code 5/16. It was rated 640 CCA but alas has dropped to 617 CCA:
It shows up as 95% good on the tester. That one will go on a tractor mounted 15 Gallon electric sprayer made by Fimco.
Finally we come to the last battery that I was previously using to power the sprayer. That is another Costco Interstate 640 CCA dated 10/14 that has fallen to 375 CCA on the tester, and that indicates Replace. That is the one I returned to Sam’s to get my $18 core charge back
