The battery is one of the most common components in need of replacement. This guide contains instructions for removing the 3.7 V lithium-ion polymer battery in the Nook BNRV300 device. This device is also called the “Nook Simple Touch.”
Without a properly-functioning battery, your Nook will not operate. First try troubleshooting your Nook device using these guides if your Nook does not power on, or your Nook will not hold a charge. If your Nook device still fails to operate properly, then follow this Nook BNRV300 Battery Replacement Guide.
Warning: If the battery is swelling, causing discoloration, or smelling bad, removing it may be dangerous. If you suspect your battery is damaged, see this helpful guide for what to do with a swollen battery.

Turn the Nook over to find the power button along the back upper edge.

Slide the back cover down towards the USB port to release it. The pictures show the case being pried open but this should not be necessary.
There is no need to pry the cover off. Just slide the back cover down toward the USB port.
This right here! It requires little to no force to do this. You are more likely to break the clips if you force it open.

Oh man, this is absolutely right! Sliding it down away from the power button is so easy. I'm sad I didn't see this comment until after I had pried it off. I couldn't figure out how to put it back on after changing the battery, but sliding it back up is easy. iFixit should definitely update the instructions to clarify this.
Looks like they updated the instructions! Although they said “prised” instead of pried. :(

Use a spudger or your fingers to gently pry the connector out of the white socket.
-
The back cover is now fully detached.

Check the comments on each step. There are some adjustments to the process to properly and safely take this apart.
You should pull up from the bottom of the button. It will hing up and pop off easier and less chance of breaking the button. There is a hing on the top side of the button to pivot down to the bottom where the button is. The clips are near the bottom of the button. You are more likely to break the pivot pins doing it from the top.
