The alternator is responsible for ensuring that the battery is always charged. Unfortunately, as the battery ages, its ability to retain a charge diminishes. Therefore, if you do not start your car for several days, you may find that your car’s battery is too weak to start the engine. To solve this problem, the best thing to do is to use a manual battery charger. To charge your car using the manual charger, you must follow the following steps.

Switch off the car’s engine and turn off the power switch.
Connect the charger’s positive cable to the battery’s positive post. To know which the positive cable is, you should look at the tape. A positive cable has a red tape. In addition, a positive cable has a red clump.

Clamp the charger’s negative cable to the engine block or to the car flame. While clamping the cable, you should ensure that you clamp the cable away from the battery. This is to prevent sparks from coming out of the battery. Also, ensure that you do not clip the cable to the fuel line, sheet metal, or carburetor.

Plug the power cord and turn the voltage switch until it equals the voltage of your car battery. Most of the batteries are 6 volts or 12 volts; therefore, you should turn the voltage switch to the battery requirements.

As the charger charges the battery, carefully observe the power gauge. The power gauge usually has a needle that rotates through a charging scale or a series of lights that glow in different colors. The needle acts as an indicator and it is meant to inform you when the battery is full.

Once the battery is fully charged, switch off the power switch and unplug the power cord from the wall outlet. Also, remove the negative power cable of the charger followed by the positive cable. Keep the manual charger to a safe place. Ignite the car and drive to whenever you want to.
