I just replaced the battery in my K4nt using a kit from newpower99.
It had everything needed (T5 and a pry tool) except contortionist training
Their directions were perfect. The back removal was the easier of the specialized tasks.
Amazon glued the
entire battery into its pocket (the kit had a 1" square of 2 sided tape for the new one). I was worried, so I took the K4 outside, onto concrete because the old battery became distorted from me prying. In the end, I won, no fire and a perfectly functional Kindle
This (the K4 one) is not a task for who do not know hazards to avoid. I have replaced other non-user replaceable batteries (same company
) without straining skill levels
