Here is just a quick guide to replace the battery in a Mobius with a capacitor. 1. The first step is to take the back shell off of the Mobius. There are two small screws on the case you will need to remove: 2. They are small Phillips head screws, take them out and the bottom of the case will hinge off at the back. 3. At the top of the photo above you will see the small two pin connector for the battery. This plug will easily pull out and then you can remove the battery. 4. All that is left to do is insert the plug on the capacitor into the same two pin connector that the battery came out of. It should insert easily and will only go in one way. Then secure the capacitor into the same position the battery was in and close your Mobius back up!
