While an APS high output alternator is a crucial component to keep your vehicle accessories working properly, it has a very valuable partner in performance within the electrical system – the battery. The battery provides the necessary power to start the engine; the alternator is responsible for providing the power to run accessories and charging the battery while the engine is running. However, if the battery charge is damaged or excessively low, it can wreak havoc on the whole power system!
When starting your vehicle, the alternator relies on the battery to provide initial power to turn the engine over. However, if the battery is weak or dead, the alternator must work harder to provide power to the vehicle’s electrical system. Essentially the alternator is trying to overcompensate for the weakened state by charging the battery at a higher voltage.
Doing so repeatedly can potentially cause the alternator to overheat, become damaged and fail prematurely.
Regardless of the cause of a weak battery – or batteries (corrosion, exposure to extreme temperatures, age, etc.), you want to protect your investment upfront and prevent damage to your APS alternator! Always be sure to follow the battery manufacturer’s recommendations for battery upkeep, charge rates, and other applicable troubleshooting tips.
