I had hoped that Nissan had improved their batteries since I had issues with both my 2015's. Alas....no. My 2020 Frontier battery is croaking. 2.5 years seems to be the lifespan. Tested it with my tester and with 2 local shop testers and all agreed that my charging system was working and the battery was croaking. As opposed to my 2 2015's (4 warranty replacements) I'm just going bite the bullet and replace it with a good battery from my local shop.
I expect 5 to 7 years out of a battery. Silly me.
