Keeping Your Battery Charged While Using The Demco Stay-In-Play DUO Supplemental Braking System  


I’m considering buying the demco stay in play. Can the battery of 2008 Jeep Wrangler still be disconnected as the manual indicates? Does the power come from the MH or must the jeep battery stay connected? Is so is there a trickle charge involved in the stay in play system?


Expert Reply:

The Demco SBS Stay-IN-Play DUO Supplemental Braking System - Proportional # SM99251 is going to be connected to your vehicle's battery to be powered which will drain your vehicle's battery. To keep the battery charged while towing you can install the BrakeBuddy Towed Vehicle Battery Charge Kit Item # BB54FR. You'll still be able to disconnect the negative battery cable like the manual indicates for flat towing.
