My 2011 still had the original battery when I sold it in 2019 and it saw plenty of extreme cold. So far so good on my 2017. I won't change it until it needs a couple jump starts (once might just be me leaving something plugged in like my cb)
Damn, that's a long time.
The battery in my 2015 started cranking a little sluggish. I had a feeling it was on the way out, but I ignored it.
Then, one day I made a store run for groceries. Came out and loaded them in the truck, and that was it. No start.
Luckily, I got a jump and was able to get it home.
Got 4-1/2 years out of that original battery, so not too bad. 8+ is excellent. Have seen a few take a **** in less than 2 years, too.
Guess it depends whether they're built on monday morning, friday afternoon, or not.....lol.
