Prius C 12V battery

Jump points are under the hood in the UBEC near the left (drivers) side strut tower.

This information is in the manual too

 

It is only available after model year 2013, model year 2012 is under the rear passenger seat.

Here's the location info.

 

...for the 2013. For the 2012, refer to the link provided by vincent1449p.

 

Note*** Not all 2013s have this. It was an early addition, I believe in February or March. Most January 2013s don't have these jump points.

 

besides a potentially substantial weight increase, are there any other downsides to replacing it w a deep cycle battery?

 

So is there a battery out to fit this car if so what brand and what size group . I read the post but no anwser

 

Post #20 has the dimensions and other details. You need to click the link.

When my original needs replacing I might go with an Odyssey or Exide AGM if they have the same size.

No way I would go with a junk-optima.

 

I installed the optima DS46B24R with no problems at all. I had to resize the battery hold which took 2 min I took the bend out of the hold down in a vice that's it . The optima was one inch long than the Toyota battery $147.50 delivered to the front door. Sorry it took so long to get this posted I had been out of town till today. The optima battery is for the regular size prius

 

I have removed the panel in front of my 2012 Prius C to try to access the battery, because I want to install a mobile Ham radio and wire it directly to the battery. There was not enough working room so I'm going to either have to also remove the seat, or remove the battery and see how much slack there is on the power cables so I have enough room to lug additional cables to the battery terminals. I may be mistaken but it did NOT look like this is a full size battery; it looked to me to be about 1/2 to 1/3 the size of a "regular" car battery. Also I don't see how you could jump this battery as is. Perhaps by removing the seat or if it's possible to pull the battery out from under the seat while keeping it connected you might be able to do so but there is no room as is to get the typical size alligator clips of jumper cables in there. As to the question about the battery's "tie-down", yes there is a bolt that holds the bottom of the vertical member to the floor so removing it should allow removing the battery.

 

But the 2014s certainly do, and I would expect the 2015s also do.

So, to remove all speculation, 2014s and 2015s can use the special jumper location provided within the engine compartment: black cable to the frame, red cable to the special jumper location.

Also 2012s to midyear 2013s must use the old battery jumping technique, whereas late 2013s may use the 2014 and later jumping technique.

However, all may use the earlier jumping technique, in a pinch.

 

There is a prius compatible optima yellow top deep cycle battery. If you search optima yellow top Prius battery, you can find it on amazon for about $150. After 4.5 years and 80k miles, my 12v battery died and I replaced it with the optima yellow Prius battery. The optima battery is slightly wider than the stock battery, BUT IT DOES FIT! The only problem is the vertical bar that secures the battery. It has a horizontal part with a right angle that won't fit back on because the right angle bend now interferes. You can either leave the bar off, or what I did was bend the angle flat and reinstall. The dealer tried to charge me $412 to replace, save yourself the $$ and buy this long lasting battery!

 

What's the part number for that optima battery?

 

It might be this one:

Product Finder | OPTIMA Batteries

YELLOWTOP DS46B24R

It's the search result on Optima site, battery for a regular 2010 Prius. If you click on the "Search Again" button and put in the data for a Prius c, it says no battery available. Maybe that's why some bracket bending is required.

 

I have a 2014 Prius c so how do I go about replacing my 12 volt battery? Does the dealer carry fresh 12 volt batteries and how can I know when mine is about to go out? Has anyone replaced a 12 volt battery themselves? What kind and where did you buy it? Thanks....ShaAnn

 

Toyota parts departments will either have or can order replacement batteries, and their service departments have equipment to do battery tests. The battery is underneath the rear seat and is easy enough to replace. The usual rule of thumb is to replace batteries every 4 to 5 years, so it seems unlikely to me that your 2014 Prius C battery would need replacement unless you've abused it by running it completely down.

 

I think if the car regularly sits idle 2~3 days, especially coupled with short trips when you do use it, this can also kill batteries prematurely. The problem being inexorable "phantom loads".

That's us as often as not, and I've taken to leaving a smart charger connected pretty much all the time. Doesn't use much juice, is just in "maintain" mode.

 

THIS.
Why are you concerned about it at this point ?

 

Can you put the battery tender to the jump point under hood or does it need to go straight to battery?
