Why Is My Arrow GPS Not Charging?

  • Updated

This guide helps you identify and resolve charging issues with your Arrow Smart Battery Pack.

 

Prerequisites

  • Arrow Smart Battery Pack and Arrow device
  • Eos-supplied charger and power supply (9–16V DC, 1.5A min)

Step-by-Step Instructions

  1. Step 1: Check the Charger and Power Supply
    • Ensure you're using the official Eos charger and not a third-party adapter.
    • Verify power supply is between 9–16V DC and provides at least 1.5 Amps.
  2. Step 2: Inspect Battery Connections
    • Check the DC power jack (1.7mm positive center pin) for dirt or damage.
    • Ensure the battery contacts are not short-circuited or damaged.
    •  
  3. Step 3: Observe Charge Indicators
    • If the fuel gauge LED blinks red continuously, allow at least 30 minutes of charging.
    • LED will turn green once the battery is fully charged.
    • Do not confuse the red Power LED (which indicates the device is on) with the charge status LED.
      • The Power LED will blink when the Arrow is about to shut down from low battery (approx. 15–20 minutes warning).
      • The charge LED, located on the battery itself, switches from red to green when charging is complete.
  4. Step 4: Reset the Internal Fuse (if disabled)
    • Disconnect and reconnect the charger to reset the internal fuse if the fuel gauge is not working.
    • If the above does not work, plug the charger without plugging it into an outlet. After 15 minutes, disconnect and reconnect, and try to charge again.

Troubleshooting Tips

  • Understand the LED Indicators
    • The red Power LED (separate from the charge LED) will turn on when the Arrow is powered on.
    • If the battery voltage gets too low, this Power LED will begin blinking about 15–20 minutes before automatic shutdown.
  • If the charge LED stays red or won’t turn on, unplug the charger, wait 1–2 minutes, and reconnect it.
  • If the battery was deeply discharged, the LED may remain off for the first 30 minutes—this is normal.
  • Do not attempt charging in extreme temperatures.

Additional Notes and Best Practices

  •  Keep Battery Cool During Use and Charging
    • If the battery becomes hot during use or charging, move it to a cooler shaded area, such as inside a vehicle or indoors away from direct sunlight.
    • Do not charge the battery if its temperature is below 41°F/5°C or above 95°F/35°C. Wait for it to return to room temperature.
  • Do not use external Li-Ion chargers.
  • Charge the battery at room temperature only.

FAQs

  • Q: Why does the fuel gauge not show anything?
    A: It may be short-circuited. Reset by reconnecting the charger to the DC jack.
  • Q: Why is the LED blinking red?
    A: Battery is critically low. Allow it to charge for at least 30 minutes.
