Because there may be a spark when you connect a jumper cable negative clamp to the battery post which can cause an explosion. Batteries emit hydrogen gas which is very volitive. Always connect the negative clamp to the engine or another ground point on the vehicle.
Negative battery or jump start post.
To connect a battery charger to a 2009 Dodge Journey, first, ensure the vehicle is turned off and the charger is unplugged. Open the hood and locate the battery; then, connect the positive (red) clamp of the charger to the positive terminal of the battery and the negative (black) clamp to the negative terminal. If the battery is deeply discharged, you may want to connect the negative clamp to a grounded metal surface on the vehicle instead of the battery terminal. Finally, plug in the charger and follow its instructions to begin charging.

The author suggests using the mnemonic "Red before Black," which indicates that you should connect the positive (red) clamp to the positive terminal of the battery first, followed by the negative (black) clamp to the negative terminal. This simple phrase helps reinforce the correct order of connections, ensuring safety and preventing potential sparks or accidents during the jump-starting process.
REMOVAL Turn the ignition switch to the Off position. Be certain that all electrical accessories are turned off. Loosen the battery negative cable terminal clamp pinch-bolt hex nut. Disconnect the battery negative cable terminal clamp from the battery negative terminal post. If necessary, use a battery terminal puller (2) to remove the terminal clamp from the battery post. Loosen the battery positive cable terminal clamp pinch-bolt hex nut. Disconnect the battery positive cable terminal clamp from the battery positive terminal post. If necessary, use a battery terminal puller (2) to remove the terminal clamp from the battery post. Remove the battery cables from the battery. Remove the battery thermal guard (1). Remove the battery hold down bolt (1) and battery hold down (2) from the battery. WARNING: Wear a suitable pair of rubber gloves (not the household type) when removing a battery by hand. Safety glasses should also be worn. If the battery is cracked or leaking, the electrolyte can burn the skin and eyes. Remove the battery from the battery tray.
Replace the battery cable with an OEM style cable. Do not use a clamp on terminal.
positive goes to the battery and negitive goes to a ground clamp on the frame..
There are two types of battery cable connections. The clamp type connects to a post on the battery and is held in place by a nut and bolt which squeeze the sides of the clamp tightly around the post. Disconnect by loosening the clamp's nut and then wiggling the clamp off of the post, start with the negative cable (black one). The bolt on type (sometimes referred to as 'side terminal' type) is bolted directly to the battery. To disconnect this type, simply unbolt it and remove the cable end from the battery. Again, start with the negative (black) cable. If the goal is not removal of the battery, but disconnection of power to the vehicle for servicing, disconnection of only the negative (black) cable is sufficient.
To charge a BMW X5 car battery, first ensure the vehicle is turned off and parked in a safe location. Connect a compatible battery charger to the battery terminals, ensuring the positive (red) clamp connects to the positive terminal and the negative (black) clamp connects to the negative terminal. Set the charger to the appropriate voltage (usually 12V) and follow the manufacturer's instructions to begin charging. Once charged, disconnect the charger, starting with the negative clamp, and check the battery's performance before driving.
To charge a car battery with a DieHard charger, first ensure the charger is unplugged. Connect the red positive clamp to the battery's positive terminal and the black negative clamp to the negative terminal. Plug in the charger and select the appropriate charging mode, if applicable. Monitor the charging process and disconnect the clamps after the battery is fully charged.
To jump a battery is exactly the same as you would jump start any other cars in the world. 1. Connect the jumper cable positive clamp (Red color) to the positive post of the dead battery. 2. Connect the jumper cable negative clamp (Black color) to the negative post of the dead battery. 3. Connect the other jumper cable positive clamp (Red color) to the positive post of a good battery. 4. Connect the other jumper cable negative clamp (Black color) to the negative post of a good battery. 5. Start your Mercedes. 6. Reverse the 1-4 steps when the car starts successfully. Note: Step 3, and 4 could be a good strong battery, or a battery on a running car. weijen_hsu@yahoo.com
