Introduction

What you need

Step 1

              Pop off the button caps.
  • Use a suction cup to remove the caps on each end. Press in and pull out. They should pop right out.

Step 2

              Unscrew the PCBs
  • Each side is held in by three tiny screws. You’ll need to take those out. Make a note of the numbers on each side. While it’s mostly interchangeable, you’ll need to keep track of which connection goes in which board.

Step 3

              Take of at least 1 of the PCBs
  • Warning: once you remove the connections to the PCBs they will be quite difficult to reattach. Unfortunately, you’ll need to at least remove one side to access the battery. I recommend starting with the side labeled 10 which does not have a power connection.

Step 4

              Remove the cap screws
  • Remove the 3 screws on the side you want to remove. In the photo here I’m removing the side with the power connection, however, I recommend you start with the other side to see if you can open it up without removing the power connection.

Step 5

              Pry open the cap(s)
  • Use a screw driver or something rigid to help you pry out the end cap(s). There is some light adhesive, but with a little force they pop out.

Step 6

              Locate the contents
  • You should now see the LED array with the battery inside.
  • If you removed both caps you should be able to slide it out.
  • If you left the other cap attached, try popping that cap out and removing the attached battery with it (I didn’t try this, but it should work).

Step 7

              Pull the battery out
  • The battery will just slide out.
  • This is as far as I’ve gotten right now. I’m a little unsure as to how to proceed at this point. But you’ll need a new battery and to be able to solder the connection to it.

To reassemble your device, follow these instructions in reverse order. It’s fairly easy to disassemble, but very difficult to replace the battery, and very difficult to put the small connections back together because of the small size and the shape of the end caps.

I haven’t tried it but I think I found a match on the battery: https://www.18650batterystore.com/produc…

If you try it, please post the results. I talked to one of the people who worked on it and he said that you could use “any lithium ion battery that can work in the same voltage range, but there are a few gotchas like how to safely attach the connector”. I don’t know too much more than that and I just haven’t had the time to learn out to attach a battery like this.
