2015 persona. My average distance to empty has been dropping for some time now when I fill up and I recently purchased the Prius app. Tested it and says I’m due for a new battery. I have time to shop around still as I feel it’s not too urgent. I’m located in San Bernardino county. Where should I get my new battery from. Is it better to get it from the dealer or a 3rd party? What experience have you gotten from different places. Cost is important. Thanks.
