Alternators

Refine Results

The battery in your vehicle is sufficient at powering some parts of your vehicle and is what allows your engine to start, but the battery doesn't have the juice to last all day. It needs some help. Fortunately, you have an alternator in place that serves as your battery's sidekick, converting mechanical energy into electrical energy. This support keeps your battery charged and other components receive the power they need to operate all day. In case the alternator fails, you can rely on your battery power to run your BMW for a short while. Although your car battery supplies the electric starter motor with power, the alternator is the auto component that charges the battery and powers electrical systems. An alternator can run for 10-15 years without requiring any repair or maintenance services. However, if you find that your dashboard lights are flickering or if your battery is new but not lasting, it's time to have your alternator checked. If you need a replacement, you're in the right place. When installing your alternator, avoid buying an aftermarket part, as it may not serve you for long. Instead, insist on buying a genuine alternator to prevent your car from stalling. When you purchase a factory OEM alternator from our store below, you'll be getting a durable part made for your specific make and model. Place your order and let us help you keep your BMW on the road.
