Recharge & Maintain Car Batteries







Automobile batteries can provide a lot of power, even under the most difficult of conditions. However, a battery left idle for a long period will eventually discharge. Similarly, a battery that is used for long periods of time but that is improperly charged will eventually discharge as well. One way of recharging and maintaining a battery is by using a trickle-charger. This method of charging is generally regarded as safe, and can prolong battery life. Battery maintenance also includes checking the cable terminal connections and battery posts for corrosion. Keeping these clean and free of oxidization (in the form of green or white "rust") is important.


Instructions


1. Check the battery cables, terminal clamps, and battery posts for corrosion. If corrosion is present, place baking soda in one of the cups, and fill the cup with water. Mix the baking soda and water solution with the old toothbrush. Pour the baking soda/water solution on the corroded battery parts. Scrub the corrosion off with the toothbrush. Fill the second cup with water, and rinse the baking soda solution off the battery parts. Dry the parts with the paper towels.








2. Connect the red clamp from the trickle charger to the positive terminal on the battery. Connect the black clamp from the trickle charger to the negative terminal on the battery. Check that the clamps are firmly connected to the battery. Plug the trickle charger into an electrical outlet and turn the charger on. After approximately two hours, check the trickle charger.


If using a charger with a "Full Charge" indicator, go to Step 3. If using a charger without a charging indicator, go to Step 4.


3. Check to see if the "Full Charge" indicator is lit. If the indicator is not lit, then check back once every half-hour until the "Full Charge" indicator is lit. Unplug the charger from the electrical outlet. Remove the black battery clamp and then remove the red battery clamp.


4. Check to see if the battery is hot to the touch. If it is, then unplug the trickle charger immediately, remove the black battery clamp first, and then remove the red battery clamp. If the battery is warm to the touch, then continue charging it. Check the battery every half-hour until the fourth hour. If the battery is still warm to the touch, then remove the battery charger to avoid overcharging. Remove the battery clamps: black first, and then red.
