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 your battery has fallen below 15% charge—this is indicated when the LED light on top of the mouse is red. 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.

-
Before you begin, flip the mouse's power switch into the red OFF position.
-
Unplug all cables from your mouse.
-
-
-
Heat an iOpener and lay it on the mouse feet for one minute to heat the adhesive.
-
-
-
Slide the tip of an opening pick under an edge of the bottom mouse foot, making sure it goes under both the foot and its adhesive pad.
-
Gently slide your pick farther under the foot and lift until you can grip it with your fingers.
-
Use your fingers to peel up and remove the foot.
-
-
-
Slide the flat end of a spudger under an edge of the adhesive. If the adhesive seems stuck, you may need to heat it further.
-
Peel the adhesive off.
-
If any of the feet got damaged during removal or separated from their adhesive pads, replace them.
-
Use a spudger to carefully scrape up and remove any remaining adhesive bits.
-
Use isopropyl alcohol and a microfiber cloth to thoroughly clean all adhesive residue from the foot recesses. Allow the surface to completely dry.
-
Remove the feet from their backing and firmly press them into place.
-
-
-
Repeat the process to remove the two pentagonal mouse feet on the left and right sides.
-
-
-
Heat an iOpener and apply it to the Logitech sticker for one minute to soften its adhesive.
-
-
-
-
Slide the tip of an opening pick under an edge of the Logitech sticker.
-
Gently slide your pick farther under the sticker and lift until you can grip it with your fingers.
-
Use your fingers to peel up and remove the sticker.
You don't need to fully remove this sticker, all you need to do is flip the thinnest part (like till you reach the part like in the photo above), put the screwdriver in, unscrew the screw, take the screw out and stick the sticker back on. Do the same with the other screw and during the assembly.
-
-
-
Use a Phillips screwdriver to remove the seven 4.5 mm screws securing the two halves of the mouse together.
You'll need a T5 bit to remove the seventh top screw.
It used to be that on the older models, but on the newer one I just opened it had a Philips for that last one too, just like the guide shows.
-
-
-
Swing the top case towards the rear of your mouse to access the internals.
-
Keep the top case lifted with one hand, or use something heavy to support it while you work.
-
-
-
Use a spudger or clean fingernail to flip up the hinged locking flap on the interconnect cable ZIF connector.
-
-
-
Use tweezers or your fingers to grip the interconnect cable by its pull tab and slide it out of the socket.
-
-
-
Use a pair of tweezers to firmly grasp the sides of the battery connector.
-
Pull the connector up and out of its socket, gently rocking it back and forth to loosen it.
-
-
-
Remove the top half of the mouse.
-
-
-
Heat an iOpener and lay it on the top case for two minutes.
-
-
-
Insert the tip of an opening pick under the battery, at the side opposite to the battery cable.
-
Slide the opening pick under the battery and lift to separate the adhesive.

-
Remove the battery.
-
If the battery adhesive is still sticky, you can reuse it. Otherwise, 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.
-

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.
