How to Insert the Battery

18650 battery and charger required!

The PLT-1B does NOT include a battery nor a charging circuit. You will need to supply your own flat-top, unprotected 18650 Li-ion cell, and a separate 18650 charger. Recommended cell: Samsung 30Q 18650 3000mAh.

1. Gently press your thumb on the case above the stake and the lid should pop off.

2. Hold the case and push the stake down a bit, then gently lift it out of the bottom case section.

3. Flip the PLT-1B over and identify the + and - markings. The + is on the left side and the - is on the right side. Double check before going any further.

4. The top of the battery (the positive end, marked with a + and a small ring around the terminal) goes on the left side, matching the + on the PLT-1B.

5. Hold the PCB. You'll need to use a bit of force to push in the battery. Start with the right - side, then push in the left + side.

6. Flip the sensor back over and lay the PCB inside the case so it sits flat.

7. Line up the notch in the top left of the lid, then gently press down until the lid snaps into place.

You have now installed or reinstalled the battery!
