No LED on the charger or battery when plugged in; battery does not charge.

Safety first: Unplug the charger before inspecting the cable. Do not use a charger with exposed wires.

Steps to try:

• Check outlet: Test the mains socket with another appliance to confirm power is present.
• Inspect charger: Look for damage to the cable, plug, or casing. If any damage is visible, stop using it immediately.
• Test with another battery: If available, try charging a second Gtech battery. If neither battery charges or lights the LEDs, the charger is faulty.
• Replace charger: Obtain a genuine Gtech replacement charger with the correct voltage and connector for your model.
