Battery information

The DG-8 uses a single protected lithium-ion polymer battery that is rechargeable, but is

not user-replaceable.
Battery run time is typically 22 hours. All batteries self-discharge over time; TEC

recommends charging the battery using the included fast charger at least once every

three months regardless of battery level.

Charging instructions

The DG-8 battery is charged through its USB-C receptacle. When using the included

USB-C power supply and USB-C cable, the DG-8 will charge from empty to 100% in

approximately 2 hours. When charging the DG-8 using an aftermarket USB-A to USB-C

cable it will take approximately 5 hours to fully charge from empty.
When the DG-8 is connected to a power source, the green LED light next to the USB-C

port will be lit. While the battery is actively charging the orange LED light located on the

opposite side of the USB-C port will be lit as well. Once fully charged, the orange LED

will turn off.
The DG-8 battery should only be charged between 32° F and 115° F (0° C and 45° C).
TEC recommends using the supplied USB-C cable and power supply for optimal

charging.

Temperature thresholds

The DG-8 should be stored in a dry place with temperatrue between 32° F and 77° F (0°

C and 25° C). Operating temperatures are between 32° F and 115° F (0° C and 45° C).

Calibration information

The DG-8 should be calibrated at the TEC calibration lab once every two years. The

date of calibration can be found on the label on the back of the gauge. Visit the TEC

website for more information on arranging calibration service.
