Built-In Battery Charger and Tester
The integrated charger keeps the included battery charged and ready to go. At any time, if you would like to see what the state of the rechargeable battery is, just push the green button and LEDs will light up to indicate the battery's status. If it's green, it means the battery is fully charged. Yellow shows it's currently charging, and red indicates a low battery.

Quick Tips:
- When you store your trailer, be sure to keep the pin plugged into the breakaway switch. If the pin's removed for an extended period of time, dirt and moisture can get into the switch and cause corrosion that could keep it from activating when you need it.
- A breakaway system needs to be able to apply the trailer brakes fully for at least 15 minutes. In general, the heavier your trailer, the higher amperage battery you'll need for the breakaway.
