6.5 years on a battery - new personal record!

Late model vehicles, i think 5-8 years is the norm anymore. Oreillys has been decent for Me, as well as Napa. As far as old cars, with high compression, electric fans, electric fuel pumps, and a mix of 50 year old, and new wiring, and they sit all winter with a tender on them; I feel like my norm is 3-4 summers. Or "Long enough to make you look stupid at a car show when it dies unexpectedly". Whichever comes first
