Thanks, knc1.

I have difficulty believing any aftermarket battery for a paperwhite is much younger than the one already in there. The brand offered by NP99 for 30 dollars or so is identical to that offered on eBay for 10. There seems to be very little demand, so I suspect the supply is ancient and I would not trust it.

This is off topic of course, but I really am disappointed that our handhelds are disposable. I would keep my paperwhite forever if there were a standard battery I could replace every few years.

Perhaps when my PW1 finally fails it will finally inspire me to get around to one of my autodidact bucket list items: the Nand2tetris course and I could remake the game as my final project.


If you really wanted to, you can consider this:

geekmasterbought a new battery, and hooked into the circuit for his kindle battery. Needs to re-use the board inside for reasons.

Yay! It works! Now to unplug it from the charger to see if that battery is acceptable to the kindle. I will test it, then do a restart from the settings menu, and test it again...

Umm... the LED only stayed on (amber) a few seconds after unplugging it -- BUT it did NOT come on after replugging the power, until I jiggled the battery module. Yeah, it flexes too much wihout extra support.

VERY carefully (so as not to wiggle the battery, on battery power only (no USB cable): "menu / settings / menu / restart". It restarted. It displayed the GUI framework (showing all those books), but with a popup warning that my battery is running low and I should connect it to a charger.

YES! My "battery surgery" was successful!

Any old cheap LiPo battery CAN impersonate an authentic amazon battery (with a "brain" transplant -- i.e. that little circuit board harvested from the old dead battery).

Enjoy!

EDIT: Though I wonder if this tiny little 500mAh battery can last long, especially when it has been unused and uncharged for a couple of years... ESPECIALLY if I use it to play videos with my kindle video player, eh? But for just book reading? Probably a lot longer than using my smartphone to read books, for sure...
