If your Arlo Pro 2 or Arlo Pro camera’s battery has a low charge (15% or less), plug in your camera or insert a fresh battery. You can use an Arlo Charging Station and an Arlo Pro Rechargeable Battery to make sure that you always have a fresh battery available.
If your battery is completely dead and does not charge, follow these troubleshooting steps:
Remove the battery from your camera.
If your camera is plugged in, unplug your camera’s AC power adapter cable.
Plug your camera back in to the AC adapter that came with the camera. Note: Make sure that you are using the power adapter and adapter cable that came with your camera. A regular 5V USB cable cannot provide enough power to charge your camera’s battery properly.
