I cannot find a replacement starting battery for my 2016 Prius 2. The only option is buying one from Toyota for an exorbitant price. Does anybody out there know of a standard group number battery that will fit?
I have tried all the auto parts stores, Auto Zone, O'Reilly, Advanced, NAPA, etc. Nobody even lists a replacement battery. Starting battery for my generation 3 Prius was easy to find. Walmart even has them.
I ran into the same problem on my gen 1. I found a conversation kit on line using an Optum battery. Check online. The battery itself does not need high cranking amps as its only purpose is powering lights and electronics.
