How to install a car battery is something that every car owner should know. First, boost charge the batteries for top efficiency prior to installation. It is not that difficult to install a car battery.



You will do the battery installation when you replace your car battery. If you replace your car battery, use only a battery of the same model and the same specification as that of the battery to be replaced. Otherwise, you may encounter problems like inconsistent dimensions or different terminal positions, thus it is likely to cause battery damage, leakage or fire.

In the event of battery damage, the battery power will be insufficient, making it difficult to start the vehicle. In such a situation, it is suggested that you go to a car shop and have the battery charged or replaced.

How to install a car battery

Step1. Boost charge the wet batteries to ensure top efficiency before installing.

Step2. Clean first the battery terminal posts thoroughly with a wire brush, remove any corrosion that already accumulates on the battery pole. Ensure that the terminal post is free from corrosion. If you can make the metal shine then it is better.

Step3. Turn off all lights and accessories that use electrical power. By doing so, it will minimize the possibility of sparks while installing the battery which may possibly cause a short circuit.

Step4. Observe and inspect all the lights if there is one that fails to turn off because if there is one light that always keeps on when the battery is replaced with a new one it will possibly drain the new battery.

Step5. Carefully mark the polarity cable as positive or negative for identification because this will ensure that the correct polarity is connected to the correct terminal post when installing a new battery.

Step6. Now, remove the old battery from the car by disconnecting the ground cable first.

Step7. After the old battery was removed examine the battery carrier and the battery fix that use to hold down the battery from the carrier or seat, make sure that those parts are in good condition. Clean the battery fix if necessary.

Step8. Check the battery cables for any fraying of insulation, cracked or worn. If the cables are damaged it will not do an adequate job of delivering power. If there is a problem with the cables replaces them if necessary.

Step9. Thoroughly clean the battery connections before installing the new battery. Make sure that the connections are free from any rush and corrosion.

Step10. Check the fan belt. Make sure that the alternator fan belt is properly tightened because a loose or slipping belt will cause the battery not to recharge properly.

Step11. Install the new battery. Double-check the polarity to make sure that it is connected to the right terminal. Connect the ungrounded cable first.

Step12. Now check for any shorts circuit. To make a short circuit test, connect the meter between the battery and ground cable. There should be no movement of the needle on the meter. If there is movement, there is a short somewhere in the electrical system which must be repaired immediately.

Step13. Install the battery fix to hold down the battery from its position.

Step14. Coat the battery terminals with a non-metallic grease to prevent corrosion on the terminal.

Step15. Run the engine at fast idle for ten minutes.

Step16.While the engine is running, use the meter to check the alternator and voltage regulator output. This is very important because a faulty alternator or voltage regulator can cause a premature battery failure and you do not want this to happen.
