If you're in the market for a new auto electrical part, it's important to know what to look for. Here are some tips on how to choose the right alternator:
1. Size. The size of your alternator will dictate its output power and frequency. Alternators with higher outputs and frequencies are typically used on high-performance vehicles, while lower outputs and frequencies are more common on vehicles with lower horsepower requirements. So if you plan on upgrading your vehicle in the future, make sure to get an alternator with the appropriate power rating.
2. Output type. Alternators come in two Categories: brush and brushless. Brush alternators use brushes to generate electricity, while brushless ones rely on electronic circuits to do the same thing. Both have their own benefits and drawbacks; for example, a brushless alternator is usually quieter than a brush one, but they tend to wear out faster due to the increased stress put on them from spinning motors.

3. Efficiency. In order to determine an alternator's efficiency, simply divide its wattage by its voltage (or amps by volts). A high-efficiency alternator will produce more power without using more energy than a low-efficiency one, so make sure you select one that fits your needs!
4. Certifications. Not all auto electrical parts are created equal – some have certifications that denote their quality and reliability, such as ISO 9001 or 14001 certification from bodies like the International Organization for Standardization. This can help you know that you're getting a quality part that will work as intended and meet your expectations.
