How long should an OEM battery last?

How many of these failed batteries have increased draw due to lights, stereo, compressor, etc...?

Also I forgot: how many of you failed battery people had the battery get below 80% before failure?

 

Mine lasted 4 years 85,000 miles

 

My OEM battery is still holding up after 2 years / 18k miles. I don’t have any issues with the current battery, however I’m going off to college in the fall so I might as well replace it this summer with one of the Optima Yellow or Odyssey batteries.

 

My wife’s 2019 Camry (bought new November 2018) battery went south at about 28,000 miles. Got about 2 1/4 years out of it. Covered by warranty.

My 2019 Tacoma (purchased new December 28, 2019) currently is about to hit the 29k Mark. Battery still seems to be A-Ok.
