Left my 2014 Prius 60 days so far.....

hybrid battery will be fine. if you've never run down the 12 volt, it should be fine as well. i leave mine for 35 days every winter, even when 4 years old. and my 08 still has the original battery.

Mine will be 65 days when I arrive home March 17 th.. I have a 2 amp. Smart charger on the 12 volts. Hal

 

well that's no fun.

 

You may be good. You will soon find out. Hal

 

This has me wondering... How long can a Prius sit without being started?
2 weeks?
A month?

 

the 12 volt has it's own specific warranty, usually pro rated. i'd be surprised if they sold you a new one for $90., they probably are thinking a typical car battery, but when the look up the prius part, find out it's $200. plus labor.

 

I'd move fast on that, before someone comes to their senses, lol.

Seriously, someone got confused: the battery from the parts department will likely be around $200, or a bit more. Plus a charge that's refunded when you return the old one (core charge).

 

Good to know.

Wondering what people that leave on extended deployments, etc have to do? Battery tender?

 

I am also wondering, since my Firebrid project will be down for extended periods while I am welding the two bodies together. For the 12 volt, I can always swap it in and out of my other 2 Prii, but I am wondering if I need to worry about the Hybrid battery while it is out of the car. Batteries and electronics all need to be removed during the MIG welding to prevent electrical surge damage from the arcs.

how long will the hybrid battery be out of use? you might need a grid charger.

 

It depends on many factors, most significant is what condition your battery is in. A new battery is rated at 45 Ah, and the Prius has a parasitic draw of 0.013 A (I measured). 45 / 0.013 = 3461 hrs = 144 days.

You wouldn't want to sit even half those many days because permanent damage to the battery will occur.

If the car will sit parked for a long period of time, either disconnect the battery, or put it on a float charger/solar charger.

 

The manual states that you should drive the car for 30 minutes or 10 miles "at least once every several months". Will it take you longer than 3 months? A little bit longer should be fine, especially if you store it with at least the usual 6 bars. I wouldn't go more than 6 months, though. A nearby dealer might be able to charge it for you, although I've sometimes gathered that the charger for these batteries is something that's so rarely used that they ship it from dealer to dealer only when it's needed.
