Trailer Breakaway Switch Battery: A Comprehensive Guide

When it comes to trailer safety, one of the most crucial components is the breakaway switch battery. This device plays a vital role in ensuring the security of your trailer and its occupants by automatically engaging the electric brakes in case of an accidental separation from the tow vehicle.

In this article, we'll delve into the world of trailer breakaway switch batteries, exploring their features, installation, and maintenance requirements. By the end of this guide, you'll be well-equipped to ensure the safety of your trailer on the road.

Understanding the Breakaway Switch Battery

The breakaway switch battery is designed to provide a minimum of 12 volts DC power to activate the electric brakes in case of an emergency. This battery is typically connected to the breakaway switch, which is mounted near the trailer's coupling point. When the tow vehicle and trailer separate accidentally, the breakaway kit engages the electric brakes at full power for a minimum of 15 minutes.

Battery Indicator

The battery indicator is an essential component of the breakaway switch battery system. It provides visual feedback on the battery's state of charge, helping you monitor its performance and identify any potential issues. The indicator will switch off when the battery is lower than 11 to 9 volts, indicating that it needs to be recharged or replaced.

Troubleshooting Common Issues

If the Battery Indicator does not illuminate, it may indicate a problem with the breakaway battery itself. In this case, you should recharge or replace the battery as soon as possible.

On the other hand, if the indicator flashes red, it means that only the breakaway battery is low on amp hour capacity. To resolve this issue, connect the battery indicator cable directly to the breakaway battery, insert a 10-amp fuse inline and close to the battery.

Installing the Breakaway Battery Magnetic Monitor

The remote monitor is a useful addition to your breakaway kit, providing clear visual feedback on the battery's state of charge. To install the monitor, mount it in a clear view of the driver either in the cab or on the side of the trailer or caravan.

Breakaway Kit Requirements

When using a caravan battery as a breakaway kit, ensure that you have all the necessary equipment, including the rubber boot to reduce water ingress and prevent corrosion. Additionally, make sure that your onboard 12-volt battery can provide sufficient power to activate the electric brakes in case of an emergency.

In conclusion, the trailer breakaway switch battery is a critical component of your trailer's safety system, providing a failsafe mechanism in case of accidental separation from the tow vehicle. By understanding its features and requirements, you can ensure the safety of your trailer and its occupants on the road. Remember to regularly inspect and maintain your breakaway kit to prevent any potential issues.
