Does it really kill your car battery to jump someone else's car?

The answer is yes. If the battery that you are charging has some electrical issues (usually a short) it can damage yours. However, a simple solution is to connect the jumper cable negative portion that goes to your battery to a metal section of your car, thus not allowing a feedback from the other "possibly" damaged battery.In other words: positive to positive, your negative to metal the other negative to negative.

I do believe you can damage your car battery by giving a jump start. A friend was giving a jump start to his girlfriend and his battery caught fire. He is not driving that Mercedes any longer.

Not if you know what you are doing. The correct way to make the connection are as follows: connect the cables on the first car black to neg and red to positive on the second car red to positive and the black to a good ground some metal on the engine or frame. This will eliminate the problem.

The first car is the one with the good battery.

Lead acid batteries degrade if run below 50% charge. The reason why they are ideal for cars is because overcharging them is not an issue. Connecting jumper cables incorrectly is bad and jumping with battery that has not been topped off with distilled water or has issues is also bad.

However, often when you jump another car your engine is running. In this case, the thing that is "jumping" or charging your friend's battery is being charged by the alternator which is what charges your car battery. So to summarize, no, jumping a friend's car is not bad for your battery, BUT there are things you should do to prevent user error and things you should do to maintain your battery to keep it living longer.

The possibility of a short circuit somewhere in the battery cable of the vehicle being charged. It, would short circuit your battery and alternator as well. The odds are against such an occurance ,but it is possible.

If,the battery your trying to charge is old and needs to be replaced will not take a charge.

It's never killed mine. I'd say if your battery was really weak, it might, but generally speaking, no. Now if you are talking about repeatedly doing it...alot...that could lead to problems, but for the once in a while you might do it to help some stranded soul...no.

Besides, the car recharges as you drive it, so unless you already have a problem with your battery, I'd say the answer is no.

Well electronically if you have your car running, your alternator will keep your battery charged. Maybe if you shut off the car and leave it connected, then I can see it draining your car battery. If you make the wrong battery connections from the contacts it's possible to kill the battery as well I believe because of making the wrong polarity connections, positive to positive lead so on and so fourth is the correct contact connections.

I've seen a battery almost explode once before while people were trying to jump a vehicle, so make sure you place the Jumper contacts to the right battery posts. Note: Red is the hot or the positive lead (+), Black is ground or the negative (-) lead. Make sure your jumper cables aren't worn or broken, this will ensure that the electrical connection is a solid one.

Also make sure that your car, the one that's being used as the source of power to restore the dead battery, is running before making contact connections.

Ezhang...Absolutely not if the battery that needs charging has no other faults. Once the low car battery is started with a jump, it is best to let the batteries remain connected for a few minutes, so both batteries will recharge. You must have the cables correctly connnected, negative to negative (ground) and positive to positive.

I drove a newspaper motor route for years and charged a lot of batteries!

Yes, repeated jump starts will cause damage to your electrical system. "Reverse Flow" When the car that requires the jump is cranked, for a brief second more current is redirected to the donor vehicle. Thanks.

Normally a car battery runs out of charge if you have left electronics without switching them off, Lights and perhaps the car stereo. If you have not checked the car wiring system to ascertain if there is leakage or probably short circuits that in the long run affect the battery stability. Ensure that your battery is well insulated and your system well earthed.

Jump starting a car does not run down the battery....perhaps you only loose a little charge, but if done for a longer time without being recharge you loose the charge, the trick is to jump start and then reconnect your own battery. Your connections must be well connected to avoid short circuits and ensure you have quality jumper cables to avoid arcing or heating of cables. All the best.

Yes it will kill your battery, I don't give nobody a jump not even my children.

If their car has an eletrical problem then yes.

Yes. It is never recommended to jump start anything with your vehicle, especially a bigger vehicle. Besides the possibility of killing a battery cell you can cause some major electrical issues with your battery, cable, alternator and possibly your computer.

As my elder's are connected with the business of batteries. So, according to my information and knowledge it is not like this. If you want to start another car by plugging wire to your battery, so there are some ways also for the protection.1.

First start your vehicle.2. Then plug the wires to your battery, Positive with + and negative with -.3. Then when you are going to start another car, first race your own car, I mean to say that press the accelerator, then start the another car.

If you will follow these ways and your battery blast then tell me I will send you the money for the new one. If it is very difficult for you then remove the wires of your car from your own battery and then connect the other car battery and then start easily. But both the ways, you will find beneficial, because after my great experience I want to share my views about the concern question.

It shouldn't. If your car is running, it should not drain the battery at all. I've done this many times for friends over the years and have never had a problem with it.

If it does drain it a bit, once you run your car, it should recharge your battery.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
