Problems With Using Too Large of an Auto Battery

Car manufacturers evaluate the amperage necessary for starting and operating the vehicle in different situations to determine the alternator needs. The whole charging system is based upon the evaluation of the vehicle’s needs. The battery is just one aspect of the system. Using the wrong battery in a vehicle carries several potential issues.

Alternator

The alternator installed in your vehicle is set to produce sufficient amperage to charge the battery while running the vehicle. A larger battery will initially have no impact on the alternator, but will pull greater amps during vehicle operation, causing the alternator to wear out sooner. Some people believe a larger battery is needed for after-market electronics. Change your alternator instead as electronics operate off the alternator, not the battery.
