About the Retrosound Exile EM-1

An easy way to check your charge

If your garage is full of vintage cars, lawnmowers, ATVs, and other motorized vehicles, it can be challenging to keep track of which vehicle is charged up — especially those that have to sit through seasonal storage. 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

What's in the box:

  • LED battery monitor (w/ attached 19" power and ground leads)
  • 5A ATC fuse (installed)

Retrosound Exile EM-1

Good quality product. Handy tool for quick reference of battery status. I will use it on my motorcycle battery as it is stored for the winter. I suppose I could just use my multi-meter buy I'm lazy.

Product Research


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.
