Smart Regulators and Happy Engines

A smart regulator can boost your alternator’s charging performance, which means you don’t need to run your engine as long to keep your batteries happy. Sterling Marine Power’s ProRegD digital alternator regulator can be tailored to your battery type—flooded, gel, or AGM—to ensure the most efficient four-step charging schedule. It assesses battery bank size, state of charge and current output, and varies the charging time accordingly. It can be used with any 12-volt or 24-volt alternator and with any type of battery. Importantly, the alternator’s own regulator can be left in place as a backup.
