Battery Charging

The Telos thermal imager comes with an LPS7i rechargeable Lithium-ion battery. LPS7i batteries support USB Power Delivery fast charging technology when using a standard charging set (USB Type-C cable, power adapter). Before first use, make sure the battery is fully charged. LPS 7i batteries also support wireless charging.

The icon  in the status bar will flash when the battery is low. The battery needs to be charged.

Option 1. USB Charging

1. Install the LPS7i battery in the battery compartment of the device.
2. Connect the USB cable (20) to the USB Type-C connector (16) of the device.
3. Connect the other end of the USB cable (20) to the Power Adapter (21) by removing the USB Type-A adapter.
4. Plug the Power Adapter (21) into a 100-240 V socket.
5. Wait until the battery is fully charged (indication in the status bar:  ).

If the device is off, the LED indicator (17) will display the battery charge status:
