Use this guide to replace the battery in your Kobo Clara BW (P365 model) eReader.
Important: There are two Clara BW versions: N365 and P365. Check your eReader's model number (printed near the bottom of the rear case) before starting this guide. This guide is for the P365 model. Click here for the N365 model guide instead.
If your battery isn't holding a charge or is starting to swell, it's time to change your battery!
Following this guide will remove your eReader's IP (Ingress Protection) rating, making it susceptible to water damage.
If your battery is swollen, take appropriate precautions.
Kobo supports their eReaders with a warranty. If your device is still under warranty, Kobo may be able to help. Before starting a repair, review your warranty information or check support documentation.
Note: Some photos used in this guide are of different Kobo Clara models. Any slight visual discrepancies won't affect the guide procedure.

The coating is brittle and can flake into many small pieces. Heating the coating helps, but working with it is still a time-consuming process.
-
The ZIF connector locking tabs are coated in a gel that can jam the hinge and keep the locking tab from completely unlocking. Make sure the tabs are completely upright before disconnecting any cables.
-
Depending on your repair, you might have to remove the coating completely from the connectors and their cables.
-
If at any point the coating becomes too difficult to work with, heat it for 90 seconds with an iOpener or a hair dryer.
