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 is sealed, does not require any further sealing treatments & is suitable for under bonnet use.

If you need installation advice or help, there is a toll free contact line at 1800 763 878 where 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.
