Charging a Trailer Breakaway System Battery Using the 12 Volt Circuit on a 7-Way Connector

Question

Question:

I have this emergency breakaway system installed on my trailer. Is there anyway to charge the battery when the tow vehicle is not hooked up without opening the battery box and going to the terminals directly? Is there an adapter available to use the 7 pin trailer plug as the charger attachment point?

To charge the battery in the Engager Trailer BreakAway Kit, # 20099, you can attach the wire from the 12 volt circuit on the trailer side 7-Way (1 oclock position on the back of the trailer side 7-Way where the wires attach) to the input wire on the trailer breakaway system. This system has a charger built in to it. As long as it is connected to a function 12 volt circuit it will charge the battery.

When connected to the towing vehicle and the vehicle on and/or running, the 12 volt circuit will charge the battery.

When the trailer is not connected to the towing vehicle and you want to charge the battery, you will need to remove the battery and use a regular charger like # CTEK56353. I have included a link to a video review of the charger for you.

You have to remove the top two bolts that hold the lid of the #20099 to the base of it so that it can be pulled off and the battery can be accessed. It's like this as a theft deterrent for the battery.
