Can I use my 08 TCH's 12V battery to jump start another car's battery?

Can I use my 08 TCH's 12V battery to jump start another car's battery? In this case the other car is 08 Sienna.

you could try but I doubt it has sufficient current to jumpstart the sienna. the 12 volt aux in the hybrid is a deep cycle battery and the cca is usually around 450 (or lower). you need at least 650-750 to jump start a vehicle with a dead battery.

N-O.

Making sure. It's a BIG NO. You can have YOUR battery jump started, and not even via 12 V in the trunk, but do NOT JS anyone else.

Unless it's another hybrid.

I'm curious why you can't? I was in our 09 TCH and jumped a guy in a Gmc Sierra that had left his lights on. Pretty straightforward.

Traction battery
12V battery in the trunk
Likely some other small back up batteries for all kinds of computers and devices it has. Just like your computer has a CMOS backup battery.
Why you can't jump off 12V? Because it's not charged off engine, even if engine is running. It's charged off traction battery. Because it's all monitored by who knows how many computers. Because you taking chance on draining yours - and why would you? Feeling lucky?

first of all the aux battery is not designed for cranking and the cca (current needed to crank the vehicle during winter/cold) is very low. the car you jumpstarted probably has a battery that is not completely dead but just partially drained. Note that in conventional cars/trucks, jumpstarting won't work if the battery is completely dead or shorted unless you have a large booster battery such as in tow trucks and dealerships.

on prius owner's manual, they don't recommend jumpstarting another car unless you disconnect the aux battery and use that to charge the dead battery.

Yes you can. It will start it fine. I have done it on a bigger car than that. Jump starting off the hybrid is fine. Toyota even say that it is fine.

There is no reason you can't - because you can jumpstart off the hybrid. Absolutely no issues with it. Just make sure the car is turned on.

Sure. As anything else, DAYOR

Can a hybrid jump-start a NON-hybrid?

[ This was also posted under the Prius group, which is really the wrong place for it. ]

My family has three cars -- an 02 Prius, an 07 Camry Hybrid, and an 05 Honda CRV. Now the battery is weak on the CRV, and it won't start.

I've read (specifically in the jump-starting entry on Wikipedia: http://en.wikipedia.org/wiki/Jump_start_%28vehicle%29) that a hybrid's secondary battery can't be used to jump-start a conventional vehicle, because the hybrid's 12-volt battery just is not designed to provide the surge of current that a starter requires. This seems technically reasonable to me (a software engineer w/o mechanical skills).

Prius manual

[INDENT] Prius manual clearly states that the Prius cannot be used to jump start another car.
S010 manual page 545-547.

No, at least my 07 Camry manual does not say that. But I'll stick to "don't try - don't hurt" principle.


Most people out of habit try to jump start other vehilces with the Prius, in emergency situations. Although some were able to get away with it (when jump starting vehilces with small engines), others have suffered immensely, both financially and time-wise as a result of this.

The Prius 12V auxilary battery which is used to initialize the Hybrid system and to power its accessories, is a Lead-acid AGM (Absorbed Glass Mat) Deep-Cyle battery which is not designed to produce a large amount of current at once (which is drawn by most starter motors in conventional vehicles). Thus, attempting to jump start another vehicle with the Prius, would not only impose undue stress on the AGM battery but also burn a few main fuses which are not readily available in most auto parts stores. Please bare in mind that the Prius Deep-cycle battery is more expensive than the conventional sealed type lead-acid version. To make matters even worse, I have seen the dc-dc converter (located within the inverter unit which handles the 12v battery charging cycles) bust in some Prii (plural of Prius). If this happens, the entire inverter unit has to be replaces, which is quite costly.

Like I said - out of habit or not - DAYOR
Jump-Starting a Car

And whoever wrote this has no idea how hybrids operate, as they simply do NOT idle for 15 minutes. It's ignorant bs.
  • Using a hybrid to jump-start a vehicle is no different from using a regular car. Attach the positive or red lead to the positive terminal of the dead battery, and the other positive lead to the positive terminal of the good battery. Follow the same procedure for the negative leads. Let the vehicle idle, charging the dead battery. The dead battery should start after 15 minutes of charging.

Feel free to call toyota yourself or search through this forum where this has been discussed previously.
