This skin requires the latest UCCW application, this is not a standalone apk. You can get the UCCW app from here:
1. Install the apk
2. Select to add a widget
3. Find UCCW Widgets
4. Select to add a 3x3 Widget
5. Select to add Battery Clock
6. Resize to your liking
If for whatever reason the skin does not show up try these procedures.
1. Open titanium backup and preform a back up on Battery Clock
2. Unistall Battery Clock via Titanium Backup
3. Then restore via TiBu, App Only
4. Then re-attempt the Instructions.
Follow the same instructions as root users, except use the application Carbon to back up the application.
