A jump-start is a procedure of starting a vehicle that has a discharged or depleted battery. A temporary connection is made to the jump starter, which provides the needed power to crank the engine.
Once the vehicle has been started, its normal charging system will recharge, so the jump starter can be removed. If the vehicle charging system is functional, normal operation of the vehicle will restore the charge of the battery.
The jump starter is a convenient device that acts like the battery of another vehicle and comes with its clamps attached to the battery in your another car. There are several pros of the jump starter: it eliminates the need for another running vehicle and messy jumper cables.
How it works:
Match the colored clamps of the jump starter to the battery terminals; red for positive and black for negative. Once the clamps are connected to the battery and the screen will display 'READY' icon, then you can press the engine to start your car. The jump starter transfers its cranking amperage to the battery. Then you could start your vehicle successfully.
Note: dirty or corroded battery terminals may prevent a good connection for the alligator clamps and hamper the jump starter from transferring its optimum peak amps. Therefore, taking care of your battery and battery terminals is as essential as caring for your jump starter pack.
