Battery in my '69 lasted 17 years !!

Recommended Posts

Back in 2006 Checker Auto Parts was marketing "84 Month Autolite" brand car batteries.

Logo on the side of the case had a classic look to it, so I bought one for my '69 Mustang and one for my '67 Fairlane in early December 2006.

Sold the Fairlane in 2010, so I don't know how long that battery lasted but the one in my '69 was still cranking strong this summer.   Not a ton of miles in the past 17 years but it has always been plugged into the same classic 1.75A Battery Tender year-round.   Cleaned up terminals once a year and topped off with distilled water when needed.

Well, it was last driven sometime in September~October with no issues and this past weekend it was time to put it to bed for the winter and "no-crank".   Cleaned up the terminals, and still no-go.   Put it on my bigger charger and got it up to 80%, dropped it back in and it cranked but very slowly.   

This battery finally gave up the ghost ... I don't think I've ever had a car battery last this long !! 

I now work at a CarQuest auto parts store so a DieHard Gold replaced it.   Never was a huge DieHard fan when it was part of Sears, but it is now just a name owned by Advanced Auto Parts (as is CarQuest) and the batteries are still made in the same factory as the former CarQuest brand batteries were.

Well that is amazing.  But prep yourself, because the new Diehard will die very near to the warranty period and not longer.  This last time I bought an AGM (absorbent glass mat) battery rather than the regular lead acid battery design.  So far, I have had it hold charge much better between starts (which can be a month or so between sometimes).  Good luck with your new battery, but save your pennies for about 3 yrs down the road - it will almost surely be time to replace the one you just put in....

Wow all impressive results guys ... all of you beat me by a long shot as far as actual miles driven & usage.

Never had to replace a battery in any of the 5 Mustang daily drivers that I bought new since 1994.    I kept them for 4-6 years and drove 100-130k miles. 

Found a runner up in years, but again beat me as far as miles & usage:

A friend bought a 2003 Chevy S10 brand new and he replaced the factory Delco battery around 2018 so he got 15~16 years out of this one.
