a little over 10 years.

 

Ten months, its in the back room if anyone needs it.
Replaced it with a 930 CCA and 1350 HCA Odyssey AGM Deep Cycle/starting military spec battery.

Just replaced mine. 114,000/9 yrs. It was still good but I figured it was time just as a precautionary. Can tell a big difference with the new battery.

 

9 yrs. and 136,546 miles... still got the stock battery... like Camodown I run 8 spotlights pretty much every time I drive at night... I'm starting to have some trouble out of it, I could replace it now... but I just want to see how long it will last. lol

You go from 105°F to -40°F?

That's some badass weather right there...

 

7 years and 100k miles and still going. No problems yet.

 

8 years-- Just replaced my Original Motorcraft with a Die Hard Gold. It drained for first time on last camping trip, so when when I took it in for wheel balancing, Ford Dealer said it failed a load test so I drove to Sears and got a new one.
I carry a portable jumper and like some of us, I wanted to see how long it would last.

 

5-1/2 years now and still going but she was starting to feel sluggish during this winters cold spells so i may replace here before next winter
