Electrical Repair

Recharging a car's battery :

You can recharge a battery using a commercially available battery recharger that you keep in your garage. Most automotive repair shops and parts stores offer this service as well. The battery can be recharged in the vehicle, or removed from the vehicle.

Another option for starting a vehicle with a weak battery is to jump-start it from another vehicle using jumper cables. It's a good idea to keep jumper cables in the trunk of your vehicle for roadside emergency situations.

Note :

When using jumper cables, follow the instructions that come with the cables, and observe some important safety Note.

Procedure :

  1. Begin with the red clamps. First, hook one of the red clamps to the positive terminal on the dead vehicle battery.

  2. Second, connect the other red clamp to the positive terminal on the donor (good) battery.

  3. Next, hook one of the black clamps to the negative terminal on the donor battery.

  4. Finally, hook the other black clamp onto to a clean, unpainted surface (e.g., the engine block) on the vehicle with the dead battery.

  5. Start the donor vehicle and let it run for a few seconds before starting your vehicle.

  6. Remove the cables in the reverse order from which they were connected.

An option to jumper cables is to keep a portable battery booster in your trunk for jump-starting your vehicle. In order to be effective, battery boosters do need to be kept charged. Follow the manufacturer's instructions that come with the booster for proper care and charging.
