Why Is My Arrow GPS Not Charging?

  • Updated

Use the official Eos charger with a 9–16V DC, 1.5A minimum supply. Check connections, distinguish power and charge LEDs, allow 30 minutes for critically low batteries, reset the fuse by reconnecting the charger, and charge only at room temperature within 5–35°C.

 

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.
