+description: How to Insert Battery on PLT-1B.

+# How to Insert the Battery
+
+!!! info "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: <a href="https://imrbatteries.com/products/samsung-30q-18650-3000mah-15a-battery" target="_blank" rel="noreferrer nofollow noopener">Samsung 30Q 18650 3000mAh</a>.

+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!
