What is a battery isolator? Battery isolators allow an alternator to charge multiple batteries and prevent loads on an auxiliary battery from draining the starter battery. There are two main types of battery isolators: the solenoid battery isolator and the diode battery isolator. Our Smart Battery Isolator series offers smaller, lighter, and more flexible options than traditional solenoid battery isolators, and our Diode Battery Isolator series provides a wide range of models to meet your requirements, including Schottky diode battery isolator options for isolating medical equipment batteries from vehicles batteries.
- Continuous current ratings up to 250 A
- Fully sealed diode battery isolator devices and IP67-rated solenoid battery isolator devices
- Prevents loads on an auxiliary battery from draining the starter battery
- Allows an alternator to charge multiple batteries

What are battery isolators?
Battery isolators enable an alternator to charge multiple batteries and prevent loads on an auxiliary battery from draining the starter battery. Solenoid battery isolators and diode battery isolators achieve the same goal of preventing battery drain, but work in different ways, providing advantages and disadvantages in different applications.
How do battery isolators work?
Diodes in a diode battery isolator only allow current to flow in one direction, preventing a fully charged battery from passing current to a partially charged auxiliary battery. Solenoid battery isolators use relays to control the flow of current.
