The battery is the only source of electrical power for the car. The battery is charged during vehicle operation by the alternator. If the battery is not charged sufficiently, you will not be able to start the car or use any electrical components (lights, radio, etc.).
Facts to Note:
After your mechanic installs a new battery, you may lose your personal settings for radio stations, clock, etc.
How to Fix:
Perform a load test.
Take out and change the battery if it is bad.
Clean the cables and install anti-corrosion washers.
Test charge system for proper operation.
Corrosion is the battery cable’s worst enemy. If you open the hood of your car, you may find a white or bluish powdery looking substance (dried acid) on the battery and cables. This acidic substance will corrode the battery terminal-ends and the battery cables. It is good practice to have the battery and cables checked and cleaned at regular intervals. This will stop the corrosion from building up and it will prolong the life of the battery cables. Applying Vaseline or a dielectric grease compound to the terminals of the cables will also stop any corrosion buildup.
Common symptoms indicating you may need to change the Battery:
Car does not start.
None of the electrical components work (try the lights and radio).
Importance of this service:
A battery in your car serves the same purpose as a battery in your remote control: it powers it. Without a properly working battery, your vehicle will have no electrical power, and will be unable to start.
