Make sure the battery charger is off and unplugged. Connect the red clamp to the positive terminal. Connect the black clamp to a grounded metal, the car’s frame or engine block. Once both clamps are connected, plug in the charger to an outlet.
Can you charge a car battery with a portable jump starter?
Unfortunately, this doesn’t work. A jump starter works by storing energy within its own battery array, and then releasing it in short bursts to provide enough power to start a vehicle. It is enough to start a vehicle, but nowhere near enough to recharge a vehicle battery.
How does a portable jump starter work?
Portable jump starters transfer power directly from the portable battery to a vehicle’s discharged battery. These devices work by connecting special booster cables directly into a 12-volt power port on one end and to a car battery using clamps identical to traditional booster cables on the other end.
Why don’t you connect the negative when jumping a car?
Quick Tips: Jumping a Battery Never connect the black cable to the negative (–) terminal on your dead battery. This is very dangerous, as it could result in an explosion.
How long should I keep my car running to charge the battery?

What is the difference between a battery charger and a jump starter?
Unlike a car battery charger that actually charges a battery, a jump starter helps kick-start the battery without providing it any charge through a quick burst of power. Once the car is turned on, the alternator kicks in and starts charging the battery.
How long does it take to charge a portable jump starter?

How long does a portable jump starter last?

Does a jump starter have to be fully charged?
Jump starters require charging before first use and you need to ensure they have enough charge every time you use them. Just to be sure, we recommend fully charging after every use.
Do you hook up red or black first?
Attach the red jumper cables 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 happens if you connect the negative terminal first?
It is only a safety issue. If you first connect the negative cable, then when you connect the positive cable there is a chance the wrench will complete a circuit between the battery and the chassis of the car. This will at a minimum generate a spark, but that spark could eject molten metal toward you causing injury.
What happens if you don’t ground a jumper cable?
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. Disconnect the cables and attempt to start the car with the bad battery.
How often should I drive my car to keep battery charged?
