OEM Battery Life, how long do they normally last

I still have my original battery in my 2018 SR5 CM I bought in Dec 2017. *knock on wood*. Pretty impressed, I just use the battery tool to wire brush the terminals. It has lost some voltage though. Betting probably only a year left on it at most.

 

my 2020 tundra battery just gave up the ghost without any warning. I had to jump it. Lasted 3 years 4 months.

 

I proactively replaced my OEM battery at around 2.5 years as the CCA was only about half of spec. It's cold in the winter where I live and I park outside, so maybe that was a factor.

 

My 17 made it just over 2yrs to the date i bought the truck new. ZERO warning started fine one minute ,next start deader than dead ,couldnt even jump it

 

Mine lasted 8.5 months. Replaced under warranty and that one lasted 4+ years

 

Mine was 3yrs and 8 months, started to get weak so I replaced in in November before winter set in.

 

Same here on my 2018, noticed a little volt drop even after charge and decided to proactively replace with a mew costco interstate 27f a few weeks ago. Pleased with how long my oem lasted here in South Texas.
