Break Away Battery

They are generally installed on travel trailers. They are charged by the tow vehicle while driving and allow you to operate the trailers lights, water pumps and other stuff after disconnecting from the tow vehicle. What id your operation? What do you need power for after the trailer is disconnected.

 

The breakaway battery is a 12 volt battery that you mount to the trailer and connect to the trailers 12 volt system. It is used to activate the trailer brakes if the trailer comes separated from the tow vehicle while underway.

 

You are correct, Richer is not even close.

 

Uhhhh what?? No... that is not what it is for, at all.

Its used to apply the electric brakes on the trailer in the event that the trailer becomes disconnected from whatever vehicle is towing it, bringing it to a (somewhat uncontrolled) stop, but its better than it careening on down the road with no end in sight.

Remember that there should be a separate cable that you need to connect to the tow vehicle separately that is used to pull a pin in a switch in order to activate these brakes. It needs to be attached in an appropriate spot so it will actually function correctly. If the pin can't be pulled in the event of a disconnect the whole purpose of the system is defeated.

 

I thought it was the vibrator batteries after your girlfriend breaks up with you.







While as wrong as Richter's answer, it's a better one.

 

In Richter's defense, the breakaway battery does all those things too.

 

Perhaps some do, but I have never seen one that does and I have a hard time believing that small battery powering anything other than it's intended purpose.

 

And the switch cable must be hooked tot he tow vehicle ( hitch ) or that's a ticket....assuming he's got a sharp eye.
