Charging the battery of your car

Car batteries are recharged by the engine of your vehicle. Usually, you can be doing five years with a battery before it needs to be replaced. But even the best car batteries is sometimes empty for example if your lights are left on. That can be very annoying, but fortunately, it is very easy to recharge your battery.


1. Determine which type of battery you have. You need to know to determine what type charger you need. The battery somewhere stated what kind of battery it is. Look if you can not find the battery manufacturer’s website. Also, check the voltage printed on the battery, or otherwise in the instructions of the car. There exist, among others, the following types of batteries:

  • Wet cel
  • AGM (Absorbed Glass Mat)
  • Gel
  • VRLA batteries (recombination)

2. Buy a battery charger. Buy a battery charger that suits your battery type and intended use. Most chargers work on all kinds of batteries, except for wet-cell batteries.

There are rapid chargers, but these chargers are just doing more of, and less battery becomes exhausted quickly. The newer digital models indicate how full the battery and stop automatically when the battery is full charged.

Older simple chargers, to avoid dangerous situations, is disengaged manually in time to stop charging.

3. Remove the battery from your car if necessary. In most cases you can charge the battery while the battery is still in the car. If that fails, first turn all the electronics in the car and always remove the grounded pole. [2]

4. Clean the battery terminals clean. Remove grease and grime with a little baking soda on a damp cloth or an abrasive sponge. The poles must be clean so that they can make good contact with the terminals of the battery charger.

Do not touch the terminals with bare hands, especially if there is white powder. That powder is usually dried sulfuric acid, which can burn your skin when it comes into contact.

5. Place the charger correctly. Turn the charger to the battery as far away as possible, as far as reaching the cables. Turn the charger never on top of the battery. And do this in a well-ventilated area.

6. Add distilled water to the cells of the battery if necessary. Do this only if the manufacturer requires for this type of battery, and follow the instructions in that case carefully.

7. Remove the cell caps. Some batteries are caps on top of the battery or under a yellow strip. These must be removed so that gas can escape that is built up during charging.

Charging the battery

1. Plug the charger into a wall outlet. Use only grounded electrical outlets. Otherwise, you risk a fire.

2. Place the clamps on the corresponding battery terminals. The positive terminal is typically red and can be attached to the positive terminal with the plus sign (+). The other terminal is usually black and can be connected to the negative pole to the minus (-). Make sure the clips together, or other pieces of metal on the battery or in the neighborhood, do not touch.

3. Turn the charger and set the charger to the desired voltage. Read the manual of the car or the battery voltage to determine what is appropriate. Start charging with.

4. Stay a few minutes keep an eye on the battery to see if everything goes well. Note sparks, smoke or leaking fluids. If everything appears to be the battery is properly charged.

5. Let the charger and the battery alone until the battery is full, which could last a whole night. Some chargers can be much faster, but you’d better use a slower charger and patience.

6. Check how full the battery. As indicated on the charger that the battery is full, or if the pointer indicates less than one amp, you are set.

7. First unplug the charger from the mains and only then remove the clamps. Put the caps back on the battery and put the battery back in the car if needed.

In an emergency, start your batteries with jumper cables

If your battery is dead and you do not include a charger, you can use another vehicle to initiate the vehicle with jumper cables.


  • Batteries contain acid. Damage a battery pack and a battery pack never stand in the sun.
  • Do not touch any conductive metal without the proper protection of your hands.
  • Make sure the clamps are attached to the right pole: red to the positive (+), black to the negative (-).
