I have a 2014 Prius w/ 86000 miles on it and went on a 12 day vacation to return to my car that does not turn on. The headlights don't turn on either or any of the dome lights. I'm assuming it's a dead 12v Questions I have: 1. I have changed many batteries over the years. I watched a few Youtube videos and they seem straight forward. Are there any things I need to do after I replace the battery on a Prius specifically like resetting some hybrid system switch so it can drive? Obviously I know the clock and radio might need to be reset. 2. Is going to a major auto chain and picking up a 12v battery OK or should I wait until the Toyota dealer opens up tomorrow to pick up a battery? Any advice is appreciated. Thanks in advance!
Trip meters will reset to zero, if that matters to you. Radio presets and clock lose settings too. Auto up windows “may” need recalibrating; there’s an easy DIY for that. The first start up it may give warning lights: shut down and restart and it’ll be ok. And the first few start ups it may do an odd rev up, recalibrating something. Look into memory savers: they supply power during the swap, avoid these symptoms. I use a jump pack and memory saver cable (plugs into OBD port), but it’s no big deal. I do complete disconnect if doing brake work, for example.
any proper battery is fine. i went with oem simply because i got good service out of the original, it has a good warranty, and prices were similar. study the vent tube routing before removing it.
I'm still on my original battery -- 6+ years old now -- and from all that I have read here, I would go with the OEM battery because AIUI the warranty is longer than any others.
