Battery information
The DG-1000 uses two lithium-ion batteries that are rechargeable and replaceable. TEC
recommends using only protected batteries with a button on one end, as seen here:
Battery run time and storage
Battery run time is 15 hours, depending on WiFi use and screen brightness. To help
preserve the battery run time, TEC recommends keeping the screen brightness at or
below 40% and to turn off WiFi when not needed. All batteries self-discharge over
time. TEC recommends charging the batteries for a few hours once every three months
using the fast charger regardless of battery level. Batteries should be charged in
temperatures between 32 degrees F and 105 degrees F.
Charging instructions
On DG-1000 units with serial numbers 9541 and above, the batteries can be fully charged
in about three hours using the included USB Type C charger. When connected to power
the green indicator light will illuminate. The amber indicator light will illuminate during
charging and will turn off when fully charged. The amber indicator light will blink if
there is a charging error. The gauge may be used during charging.
On DG-1000 units with serial numbers 9540 or lower, the batteries can be fully charged
in about three hours using the fast charging port and included barrel jack charger.
TEC recommends using the included power supply for optimal charging.

Calibration information
The DG-1000 should be calibrated at the TEC calibration lab once every four years.
A calibration label is located on the back of the gauge that includes the gauge serial
number and the date it was last calibrated. This information is also available in the
DG-1000 settings screen (see the Basic Use Quick Guide to learn more).
TEC recommends the Tenergy Li-Ion model 30016
battery (size 18650, 2600mAh, 3.7v, protected).
Do not use unprotected batteries.
