You seldom think about your car battery until you are in a deserted parking garage late at night and your car won’t start. Then it becomes very important in your life. Car batteries require simple and routine maintenance in order to work properly over their lives. If you can open your hood and use a wire brush, you can maintain a car battery. First thing is to pop open your hood and locate your battery. Don’t worry, it won’t bite. The 2 posts that the battery cables are connected to must be clean and free of corrosion. Corrosion can prevent the cables from getting a charge from the battery and prevent your car from starting. Simply keeping your terminals clean can keep those troubles away. Get a wire brush and scrub the contacts clean. If you are really motivated, you can remove the cables and scrub the inside of connector and the terminal post. You should have a good contact after you complete this little chore. You also need to check your water level, especially when it is hot outside. If the water level drops too low, the battery will have a difficult time holding a charge. Next time you fill up, ask the guy at the service station to check it for you. Don’t wait until your car is slow to crank up. If your battery is not putting out enough juice, it may be too late to save it. The time to save your car battery is before these symptoms show up and always have a pair of jumper cables or a battery booster in your truck. You never know if that old battery has cranked for the last time.
