Efficient Charging Without Battery Interference

Argodiode Battery Isolators enable the simultaneous charging of multiple batteries from a single alternator. This setup ensures that discharging an accessory battery, such as those used for marine electronics, does not affect the starter battery. The high-efficiency Schottky diodes used in the isolator minimize voltage drop, ensuring optimal charging performance.

Advanced Voltage Compensation

Each Argodiode Battery Isolator is fitted with a compensation diode. This feature slightly increases the output voltage of the alternator to counteract the voltage drop caused by the isolator's diodes. By simply installing the isolator into the cabling between the alternator and the batteries, you maintain effective charging without significant loss, thereby extending battery life.

Reliable Alternator Operation

Some marine alternators require DC voltage on the B+ output to initiate charging. When using traditional diode or FET splitters, the absence of return voltage from the batteries can prevent the alternator from starting. The Argodiode 80-2SC’s advanced AC diode isolators include a specialized current-limited energize input that activates the B+ when the engine’s run/stop switch is engaged, ensuring seamless alternator operation.

Installation and Usage

Installing the Argodiode Battery Isolator is straightforward. Insert the isolator into the existing cabling between your alternator and both batteries. This simple addition ensures that each battery is charged independently, promoting longer battery life and reliable power distribution across your marine vessel.
