This guide will help you troubleshoot any issues you may have.

Disassembly
Begin by taking the silicon backing off of the bank, this is held on by double sided adhesive. Use a spudger to lift it up and you should be able to pull it right off.

There are now 6 holes, all of which could be covered by a black film but it could've came off when you took off the backing. There are six screw holes, 3 among each side of the back.

Personally, I had 4 screws in the bottom 4 holes but you may have all 6. Unscrew and put your spudger in the side, underneath that plate. Do NOT put the spudger after the glossy plastic line after it, you will end up breaking the shell.

After opening up the back, there are 2 screws on each side of the board holding it in. Unscrew them both and you'll be able to pull out the cells & board as one unit. The contacts for the battery are soldered on the board and vice versa for the contacts on the batteries themselves. More often than not, problems arise from the contacts being loose on the batteries so it's recommended to peel back the paper sticker on either side to check if they came loose.
