No problem. You just get more amperage flowing to your battery which will charge it up faster and send more energy to the starter motor which will make it easier to start because the motor will turn faster because it has more amps available.
Can you double up jumper cables?
That’s it — not counting your dead car, of course. Note that if your cables are too short to connect the two batteries, you can connect two sets of jumper cables to give yourself more length. Put both cars in park (or in a gear for a manual) and turn them off.
Can you use 2 batteries to jump start a car?

Can you hook up a battery charger and jumper cables at the same time?
No problem. You just get more amperage flowing to your battery which will charge it up faster and send more energy to the starter motor which will make it easier to start because the motor will turn faster because it has more amps available.
What happens if you jump start a car wrong?
When the jumper cables are incorrectly connected, the polarity of the electrical system on the vehicle with the dead battery will be reversed for a few seconds. This can irreparably damage many of the sensitive electronic components that are common on today’s vehicles, such as on-board computers and electronic sensors.
Can you jumpstart a diesel car from a petrol car?
Q: Can you jump-start a diesel car with a petrol car? A: Yes. Contrary to popular belief, this is perfectly fine. However, you will need to ensure that the two battery voltages are the same to remove any risk of burning any of the crucial engine parts or causing an explosion.
Does Jump Start damage battery?
So what about your car when jump-starting another battery? This process will put slight stress on your battery and alternator. However, in most cases, this process is harmless. A healthy battery will be unfazed by the jump-start, and your battery will recharge as you drive.

Experts say jump starting a car in the rain is safe because the voltage of a vehicle is not high enough. “The water is not an issue as long as you do it in the right sequence,” Spring said. “Drivers need to make sure there is no water dripping on the cables.”
Can you use a BMW to jump start another car?

What happens if you connect the negative terminal first?
If you connect negative first, there are chances of short-circuiting. Note that, Red cable is positive (+) and Black cable is negative (-). Never connect the red cable to the negative battery terminal.
What happens if you put batteries in the wrong way?
Being driven into reverse polarity means that the negative terminal becomes positive and the positive terminal becomes negative. In case of a reversed polarity connected between the charger and a rechargeable battery, it will result in permanent damage and/or result in dangerous outcomes like explosion and fire.
Can you jump a diesel with two cars?
You can definitely jump-start your diesel truck with a car. Although most diesel trucks have two batteries, they run in parallel. As long as you’re able to charge one, the other one will also work.
