Chosen Solution

I’m attempting to remove the back on my Voyage in order to replace the battery. The videos from iFixit and others toss off removing the back as just sliding it down. That isn’t working on my now venerable Voyage (they were made when it was new). I’ve tried unsealing the side seam by running an iFixit triangular plastic shim, but am not having much luck. Does anyone have any suggestions on how to get the back off without busting the device. I assume the age is the problem with the seams welding shut.

Don’t be fooled by the “easy” for an old Kindle. Using my iFixit kit I was able to pry the back loose and successfully replace the battery. Both the case adhesive and the battery adhesive had hardened. It took about 20 minutes of prying very carefully to free them. I could readily have broken the whole thing. I’ve answered my own question because I received no replies.
