You will need to install a new car battery when your old one has worn out. The average life span of a car battery is three to five years. Even one that is well maintained will begin to have problems starting. To prevent any damage to your starter, install a new battery when the first signs of its life end appear.
Cleaning the Battery Area
Once the old battery has been removed, clean the clamp, pan and cables. Check the terminals in your car for any signs of corrosion. Neutralize any corrosion with a baking soda mixture. In a small bowl, combine a quarter of a cup of baking soda with a cup of water. Use an old toothbrush to apply the mixture to the corrosion to neutralize it.
Purchasing a New Battery
When you go to purchase your new car battery, be sure that the model you have chosen has the terminal posts on the same side as your old battery. A reversed battery installation can lead to serious damage. Make sure that the retailer has added a premixed electrolyte and has a partial charge to it.
Charging the New Battery
Make sure you choose a time to install a new battery when you have the opportunity to drive the car for about a half hour. Highway driving will achieve the best results.
