while Toyota battery has 2 years if installed by dealership.
Some background: the original battery of my 2004 Sienna lasted 11 years until 2014. I bought and installed Everstart battery in 2014. It’s died on Monday (just last 5 years). The Toyota original battery is Panasonic and it’s great. But Toyota is selling the replacement battery called TrueStart which is not good as Panasonic based on the reviews. I also have 2011 Camry with the original battery. It's working so far so good. Hope it will last another couple of years.
Thanks everyone for your information.
