Introduction
Use this guide to replace the battery in your Kobo Libra Colour (N428B model) eReader.
Important: There are two Libra Colour versions: N428 and N428B. Check your eReader's model number (printed on the edge of the device with the USB‑C port) before starting this guide. This guide is for the N428B model.
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.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.
Make sure each of your device's main functions still work, e.g., LED backlight, touch, Wi-Fi, etc.
For optimal performance, calibrate your newly installed battery after completing this guide.
