PocketWizard Battery Door Replacement Guide

Quick answer

To replace a worn or broken battery door on a PocketWizard Plus II, Plus, or original MultiMAX, you need a replacement door designed for those models and a careful alignment to avoid cracking the hinge tabs.

Step-by-step replacement process

1. Remove the old battery door: Open the battery compartment and slide the old door out of its hinge slots. If the door is broken, carefully remove any remaining plastic pieces from the hinge area. Do not pry with a metal tool—you may scratch the trigger body.
2. Align the new door with the hinge slots: Hold the replacement door at a slight angle and insert the two small hinge tabs into the corresponding slots on the trigger body. Ensure both tabs are fully seated before moving to the next step. If the tabs do not slide in easily, check that you are using the correct door for your model.
3. Snap the door into place: Gently press the door flat against the trigger body until it clicks into the closed position. The door should sit flush and open smoothly with light finger pressure. If the door feels loose or does not click, remove it and recheck the alignment—forcing it can crack the tabs.
4. Test the battery fit and door operation: Insert a fresh set of batteries and close the door. The door should latch securely and hold the batteries firmly in place. Give the trigger a gentle shake—if you hear rattling, the door may not be seated correctly. A properly installed door will not pop open when you squeeze the trigger body.
