OEM battery lasted 12 months!

heat kills them

 

My 2nd gen's battery was still good after 9 years. Replaced it when the local Interstate dealer had a good sale.

My Frontier's battery went 7 years, same thing. Worked fine but AGM's were on sale cheap.

 

The battery in my ‘97 F150 had been in there more than 9 years when I sold the truck.

 

18 months & 28k miles here.

 

Just replaced mine, 22 months and 35k in hot Florida. Usually get about 3 years here from my experience.

 

23 months and 27k miles before mine went a couple of weeks ago (Texas). Got it warrantied but put the warranty battery in my girlfriend's Highlander and put an Odyssey in the truck. I can hear the difference in the sound of the starter motor now and through some combination of the ECU being reset and the alternator putting less load on the motor my MPG went up too. No regrets!

 

Got mine replaced under warranty at just over 1 year ~ 9K miles
