I bought mine last year 2016 SR5 4WD at 116k miles. I'm at 140k today and it feels like new. I only had to swap the battery because I forgot to check how recent it was when I bought it.
Best Battery for Toyota 4runner
I’m on my 3rd 4Runner, they all came factory with the Panasonic battery. That damn thing wouldn’t quit till at least year 8.
I'm on my second Odyssey Extreme (first one lasted from 2017-2022) and they are pretty good. I got the 34R-PC1500T. I give it a charge once every month or two with the Odyssey charger.
I had an Optima red top in my 89 4runner and that thing lasted for 12 fucking years. Needless to say I bought another one.
When I bought my 2006 4Runner V8 three weeks ago, it had the original Panasonic battery on it's last leg and I had it replaced with a Toyota True Start battery. The 4Runner only had 109,600 miles when we had that battery replaced.
I run Panasonic in ours, so far so good.
