    I just realized that the 12v battery in my 2014 Prius is 11 years old. Other Prii owned by my family had batteries last in the 9 to 10 year range. Though the 12v battery in my 2020 Camry Hybrid failed this week, which made me realize it was time to replace the Prius battery.

    I often buy third party 12v batteries from Interstate, Autozone, NAPA, etc. But since the OEM Prius battery lasted 11 years I am inclined to use the local Toyota dealer. They quoted me $350 installed, plus tax. The battery alone is $250.

    Have people had any problems with new Toyota 12v Prius batteries? My Prius only has 92,000 miles, but it is not likely we will own it for another 11 years.

    Given my experience with the Camry 12v battery, I did not buy a Toyota Camry battery.

    Probably is time, but getting it tested is a little more definitive, especially if it’s not displaying any evidence of failure. Automotive retailers that sell batteries often will have an electronic load tester, will gratis check it and give you a print-out of the result.

    or you can buy DIY level testers, Ancel, Topdon are a couple of options. I’m using a Solar BA5 (current iteration is BA9): it tests CCA and volts, gives a verdict, either pass, pass-but-recharge, or fail.
