Want to Know How Long the OEM Prius C 12 Volt Battery Lasts?

that's how long it lasted for you. can't beat 7 years, nice price btw.

 

And it means exactly NOTHING except for that.
The next guy might get more or less; there are a LOT of determining factors.

 

My car is a 2012 that I bought in Jan of 2013. I'm still on the original.

 

Says the guy who replaced his battery at:
3 years
4 years
5 years
etc.

The personal experience of any SINGLE individual is not terribly meaningful to the rest of the world.

 

Yeah, the reason it's all over the map, is all the different ownership scenarios:

1. Driven daily for a good distance, almost without fail, for at least (say) 20 miles round trip.
2. Driven sporadically, often sitting idle for several days.
3. Always diligent that lights are off and all doors closed.
4. Once in a while a door has been left ajar, overnight, or the map lights, or the head lights.
5. Car frequently gets professional interior cleaning, with doors left open for hours. Staff may be using the car radio.
6. Protracted idling, or sitting with the car in accessory mode, listening to radio.
8. Car sometimes sits for multiple weeks, say at airport, or just in storage.
9. Car is used infrequently, but the owner monitors diligently, using multimeter and electronic load tester, and uses modern charger, one capable of being left on indefinitely, pretty much every time the car will be idle for more than a day.
10. More so with a conventional battery than AGM: battery is occasionally removed from the car, posts cleaned, ditto for cable clamps, and battery levels topped up with distilled water.

 

i think more people drain their batteries than remember, or care to admit. it's just such a different paradigm with prius, they figure jump it and you're good to go, no harm, no foul.

 

i'm shootin' for 12

 

i check mine on a regular basis, so i won't get blindsided. (i hope )

 

Thank you very much Bisco for your reply. Question: is your vehicle parked in a garage? I am thinking a garaged vehicle battery lifespan should be longer than one that is not.

 

Mine has never been garaged and I just replaced the factory battery. 117k miles/7 years.

 

The only environmental factor that is hard on batteries is HEAT.
So that would be an advantage ONLY if the temperature in the garage is significantly less than it is outdoors.
