Use this guide to replace the battery in a Logitech G903 wireless gaming mouse.
Lithium-ion batteries have a limited lifespan. If your mouse dies quickly and doesn't hold a charge, it may be time to replace the battery.
If possible, follow this guide after the battery has fallen below 15% charge—this is indicated when the LED light on top of the mouse is flashing one red bar. While your G903 has a relatively small battery, any charged battery is a potential safety hazard if accidentally bent or punctured.
If your battery is swollen, take appropriate precautions.
You might need replacement adhesive to reattach components when reassembling the device.

Gently slide the pick farther under the foot and lift until you can grip it with your fingers.

If any of the feet got damaged during removal or separated from their adhesive pads, replace them.

Repeat the process to remove the two pentagonal mouse feet on the left and right sides.

-
Remove the battery.
-
If the battery adhesive is still sticky, you can reuse it. Otherwise, use high-concentration (>90%) isopropyl alcohol and a microfiber or lint-free cloth to remove all the old battery adhesive.
-
If your new battery has adhesive pre-installed, remove the plastic liner to expose the adhesive. Otherwise, apply strips of thin, double-sided tape to the battery well (not directly to the battery) where the old adhesive was.
-
Firmly press the battery into place, making sure the cables are near the rear of the case.
-
To reassemble your device, follow these instructions in reverse order.
For optimal performance, calibrate your newly installed battery after completing this guide.

This guide helped me on my G900's battery. Thank you!
G903: Easy peasy. Took longer to clean the glue residues up than to open, replace the battery and close it back up.
