The main function of an alternator is to charge the vehicle's battery and supply electrical power to its various components while the engine is running. When the alternator is functioning properly, it generates electricity and sends it to the battery, recharging it and maintaining its charge level.
However, if the alternator develops a fault or fails, it may not be able to generate sufficient electricity or may stop generating electricity altogether. Consequently, the battery will not receive the necessary charge to maintain its charge level.
As a result, the battery will gradually discharge as it supplies power to the vehicle's electrical components, such as lights, ignition, audio system, and more. Over time, if the alternator issue is not resolved and the battery continues to discharge, it can become deeply discharged and eventually lose its ability to hold a charge, rendering it useless.
To prevent draining a new battery, it is important to have the alternator checked and repaired or replaced as soon as any signs of a charging system issue arise. This way, the battery can be properly recharged and maintain its lifespan.
