Hello there, Christopher!
I’m so glad you used the force to find planDisney. I’m a force-sensitive panelist who loves answering questions about Star Wars: Galaxy’s Edge. I have my lightsaber proudly displayed on the wall next to my desk, so I understand how important it is to have your lightsaber intact.
If you need to find out how to replace the batteries, I recommend checking out this
Jedi-like response from Marc L. It sounds like you already know how to change the batteries, and you are missing the battery canister inside of the lightsaber. In that case, I recommend asking a Cast Member the next time you visit
Savi’s Workshop - Handbuilt Lightsabers at Disney’s Hollywood Studios. Alternatively, I’ve never seen a battery pack offered, but you may have luck asking a Cast Member at the
Star Wars Galactic Outpost at Disney Springs, which doesn’t require a theme park ticket to visit. Again, I’ve seen separate blades offered in these shops and
shopDisney, but I’m not sure they’ll be able to sell a separate battery pack.
Your next best option is to search online for lightsaber battery pack replacement parts. I’m sure the force will be with you, and you will be able to find some options online that could work.
May the magic be with you!
Melanie
