there are only 3 companies that make batteries,johnson control,exide and east penn.....east penn is the best, then johnson control and then exide
Hmmmm Verrrrrrry Interesting!!!!! (as ARTE JOHNSON used to say)
Call me a sucker but being in Florida I go to the drive in Sears and get a Diehard... they are all geared up to get you in and out FAST
and easy to make a claim if they die before their time!
I noticed my original battery was replaced by the first owner it seems undersized... I am contemplating replacing it so I do not have a repeat of the "Great Battery in the Fan Blade disaster of 1977" when I let my boss hop on my 1970 396 Chevelle SS around the block and the bungie cords did not hold and faster than you can say "Where is the short?" The engine had a refreshing acid bath!
So Dealer Battery or Sears Die Hard Gold?
The size of the battery is not the important thing. Very frankly, if you have no way of testing the new battery you are contemplating buying... simply lift it! The heavier the battery, the more lead and the more power (that is a slight oversimplification, but only slight). The lighter the battery, the less lead and the less power. But that is only a poorboys way of testing. CCA rating and actual testing of CCA is important. I have spent my life in automotive work and have tested more batteries than I ever want to remember and the size of the case is not at all the final word in the power of the battery. My OTC tester tests CCA's, CA's, AH's, as well as a whole lot of other things and you would be surprised how few batteries test just what they are rated for. A lot of batteries test above what they are rated for and quite a few (brand new, fully charged) test below what they are rated for, some of them way below! Buy the battery based on the CCA's that you want (that will fit in your case), and then have them test it for ACTUAL CCA's BEFORE you buy it. If they won't test it for that, I'd buy somewhere else where they will. I bought a new battery for my motorhome at Sam's Club and for curiosity sake tested it when I got home before installing. It tested at 12.76V (good) and 90CCA's !
It was rated at 650 CCA's! I tested it a few hours later at 200+ CCA's, then at 100+ CCA's! Junk! When I took it back I had them test it and they said it was fine! Got my money back and went and bought a battery from someone who knew what they were doing. Which tested above what it was rated for!
