Here is How to Use Car Battery Charger

Before you learn how to use car battery charger, make sure the battery is the real reason it won’t start. If you turn on the ignition and hear a cranking sound from the engine, it’s not a dead battery; attempting to jump-start it will be pointless. If the car won’t start when you turn the key, but there’s no noise, or perhaps just clicks, it’s likely that you have a dead battery and only jump-starting it is possible.

What you Need Before You Use Car Battery Charger

  • Owner’s Manual
  • Your Battery
  • Eye Protection

How to Use Car Battery Charger

The procedure to use car battery charger is as follows:

  1. Always read the owner’s guide! The procedures for jump-starting a vehicle with a positive ground are different in the unlikely event that it has one (extremely uncommon). Additionally, some manufacturers do not allow them.
  2. Wear safety gear and eye protection.
  3. Power off the vehicle and remove the keys from the switch.
  4. Make certain the automobile is not near any flammable liquids or gases, particularly if you are wearing gloves.
  5. It’s best to keep the charger at least a meter (3.280 feet) away from the battery, depending on the lengths of the cables.
  6. Look up the voltage of your battery charger in the owner’s manual. Make sure the output voltage of the jump starter or car battery charger is compatible with your battery charger. This is generally a 12-volt supply.
  7. On your vehicle battery, look for the “P,” “POS,” or “+” insignia. Before connecting the cables, remove any excessive corrosion.
  8. Locate the positive and negative clamps/clips on your car battery charger.
  9. Before connecting the jump starter’s jumper clamps to the automobile’s battery, make sure the device is “off.”
  10. Do not allow the positive and negative clamps to touch each other.
  11. Connect the jumper cables to the corresponding terminals for both the vehicle and jump starter if they are both off.
  12. Connect the red clamp to the battery’s positive terminal first.
  13. Make sure the clamps are properly fastened so they don’t come loose.
  14. If the car won’t start after the first try, wait 2-3 minutes to attempt again. If the vehicle won’t start after 4 or 5 attempts, you might need a new battery.
  15. If you have to readjust the jumper clamps, turn off the engine and jump starter first.
  16. Turn the jump starter off once the engine is running.
  17. Remove the negative (black) clamp and the positive (red) clamp in that sequence. Now safely store the portable jump starter.
  18. Allow the car to idle for a few minutes after removing the clamps. You may now return home in safety.
  19. It’s critical to recharge the jump starter as soon as you get home. The majority of portable jump starters operate on a 110-volt circuit, which means they can be plugged straight into an AC outlet. Recharge the gadget for at least 3 hours. Some units will require 12 to 24 hours for a full charge.
  20. It’s also essential to have your car battery checked by a local auto repair facility to see if a new battery is required and how long the battery will last.
