No dual battery setup is complete without a Ridge Ryder dual battery isolator. This unit ensures your main battery always stays at full charge by automatically detecting the voltage - cutting alternator charge to the secondary battery when your primary falls too low, and re-engaging parallel charging when the voltage returns to an acceptable level. The manual override switch on top allows you to control the connection, meaning that if you've got a flat starter you can draw on power from your secondary battery to get going, or run emergency accessories.
This unit once installed is fully water and dustproof, and doesn't require any further treating. If you need installation advice or help, there is a toll free contact line at 1800 763 878 so you can talk to one of our experts. This unit may not be suitable for vehicles with a variable voltage alternator, check with the vehicle manufacturer for more information.
