Which battery terminal do you connect first when jumping?
positive cables
Safety First: Remember, when connecting the positive cables to the batteries, you should always start by connecting the dead battery first. If you feed energy into the cables before they are connected to your battery, you can cause a safety hazard.
When jump starting do you connect positive or negative first?
Start by clamping one red cable to the positive side of the battery that won’t start. Then attach the other red clamp to the positive side of the working battery. Next, clamp one black cable to the negative side of the working battery.

What do you ground when jumping a car?
The reason for connecting the negative cable to ground rather than to the negative terminal of the dead battery is to minimize the chances of a spark near the battery, where there may be potentially explosive gasses.
How do you jump start two cars with the same battery?
Both cars should be put into park and powered off to begin the process. Notice again which terminal on each battery is positive, and which is negative. Then, attach the jumper cables to the appropriate places. The positive (red) cable should be attached to the positive terminals on each battery.
How do you connect jumper cables to a car battery?
It’s important to connect the jumper cables to the correct battery terminals. The red connector clamp will connect to the positive battery terminal/post and the black connector clamp will connect to the negative battery terminal/post.
Can you use a portable power unit to jump start a car?
Jumpstarter/Portable Power Units are becoming very popular and can be carried with the vehicle in case of battery failure. If another vehicle isn’t available for the jump start, use one to jump start by connecting it to the dead battery following the steps above.
