Jump starting another car

[Togfather]

I have just got a new Mitsubishi Outlander PHEV Dynamic Safety in diamond red and I love it.

I am disabled and need height because bending my knees is very painful and this car is so easy to get in and out of.

My daughter has a Jeep and it has a flat battery so I said I would jump start it for her, but I cannot see the battery to attach the jump leads to. My question therefore is: Can I jump start another car using jump leads, and if so, how do I do it?

Many thanks in advance, Tog.

The short answer is that you cannot.

The PHEV 12 volt battery is tiny, and cannot deliver enough current to start a car.

Other members of this forum have bought portable lithium batteries so that they can still jump-start other people's cars.

Thank you so much for taking the time to reply.

Dont do it.

Please read the user manual that came with your car to learn how to get the best from it and to prevent damage to it.

Patronising much!

I am not an idiot.

I have already read the manual, in fact i read it before I bought the car. All 594 pages.

There is nothing in there about jump starting another car, which is why I posted the question.

As you're not an idiot and have read all 594 pages, I'm surprised that you don't remember the NOTE on p 9-03 that says "You cannot rescue another vehicle's discharged battery by connecting jumper cables while using this jumper cable terminal"

You're welcome, pompous much!

Oh yes, well of course the first thing to note is that when someone says they are not an idiot - they often are, and that is definitely so in my case.

I am a member of Mensa, but there is a thin line between genius and insanity - and the older I get (now 69) the more often I cross it.

I am also bipolar, which makes me very snippy at times, so I apologise for the tone of my last reply.

Thank you so much for your time and assistance.

Best wishes

No worries Tog me old pal. I'm a curmudgeonly old git and I'm only 48

It wasn't meant in a patronising way, but there is a lot to learn about these vehicles that is different to others that it really is worth reading the manual cover to cover when you first get it, and then again a few months down the line when more of it makes sense. the pdf version is worth having too, as the find function can help to find stuff that is not obvious from the index.

Hello, in fact the note in the manual stating that it is impossible to jumpstart another (regular) car intends to protect the DC-DC converter that is used for charging the 12V battery in Mitsu Outlander. The Outlander can be used for this job with the risk of damaging the above converter. I used the red + and a shock absorber protruding bolt (-) to connect usual cables to jumpstart a Skoda Octavia (petrol engine) of my colleague in bad need knowing that he had a quite new battery in good condition and the drain would be limited just to a few seconds. While the Yuasa 12V battery can be easily replaced (sits in the trunk left), of course the converter would be a bigger issue and I do not recommend jumpstarting other cars with compliance with the Mitsu manual.

You could trickle charge a car in need of jumping for a while with little risk provided you know their battery is not totally dead but make sure you disconnect when the stater motor of the car being jumped is turned on as that is what pulls the voltage low and increases the current from the jumper to the jumpee.

I carry a portable jump starter which can be used to rescue myself or others...safest way to help. I just have to remember to charge it very few months to keep it ready. It saved me once on my Prius when I had inadvertently left the interior light on overnight.
