If you want to remove the battery, gently press the battery release button with your thumb as shown in the video, and pull the battery/handle with your other hand.
Re-attaching the battery
The battery has 3 silver contacts which are labeled with "front", "+", "-"(Please see photo below).
Make sure they are aligned with the ones inside the unit's battery slot. The release button lock should also be aligned with the release button at the side of the gun.
Once everything is aligned, insert and push the battery to the unit until you hear a clicking sound.
