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 short circuit.

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

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.
