Our take on the Retrosound Exile EM-1

An easy way to check your charge

The Exile EM-1 LED battery monitor from RetroSound makes it easy to check your battery's status with just a glance. The red, yellow, and green lights will let you know what's ready to go and what needs a charge. Warranty: 1 year

LED Battery Monitor: The Exile LED Battery Monitor (EM-1) allows you to easily check the status of your vehicle's battery. It features IP-65 water/dust resistant connections and housing. The LED Battery Monitor's 19" power/ground leads are terminated by O-rings (0.5625" ID) which connect to your battery's power and ground terminals. A 5-amp fuse is pre-installed on the power lead. Red, Yellow, and Green LED indicators provide real-time visual status of your battery. Once the EM-1 is connected to your vehicle's battery, the indicators will flicker according to the battery's charging status.

  • Green = 12.7V charge level, no action needed
  • Yellow = 12.45V-12.69V charge level, charging recommended
  • Red = Below 12.44V, charge immediately
Note: The LED lights draw very little current from your vehicle's battery and can remain permanently connected to the battery all year around.
