Logitech G903 Battery Replacement

简介

Use this guide to replace the battery in a Logitech G903.

If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your device. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

This guide requires removing the mouse feet. If you’re planning to reuse your existing mouse feet, note that the adhesive needs to be thoroughly heated for them to be cleanly removed.

You might need replacement adhesive to reattach components when reassembling the device.

If you don't want to remove the sticker all the way, you can puncture it with a screwdriver where the two screws are located beneath it. Use this picture to make sure you're hitting the right spots.

步骤 14 Heat the battery adhesive

The battery housing is not in direct contact with the outer mouse cover. Because of that you might need to repeat the heating procedure a couple of times to loosen the battery adhesive enough in order to remove the battery.
Heat an iOpener and apply it to the back of the mouse.
A hair dryer or heat gun may also be used, but be careful not to overheat the battery as it is susceptible to heat damage.
At higher temperatures the plastic mouse cover becomes heat sensitive. Avoid overheating it.

Insert an opening pick in to the gap between the battery housing and the battery at the side opposite to the battery cable.
Slide the opening pick under the battery and lift up to pry the battery off of its housing.
Make sure you push underneath the battery and not into it. Take care not to puncture or bend the battery with your tool—a punctured or bent battery may leak dangerous chemicals or cause a thermal event.
In case you have trouble prying up the battery with an opening pick, you can try to use a spudger instead as seen in this picture. When working with a spudger take extra care not to bend the battery.
If you encounter significant resistance, pause and heat the adhesive further.
Remove the battery.
Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.
It is likely you can reuse the old adhesive with the new battery. If you wish to replace the adhesive instead, remove the old adhesive and wipe away any adhesive residue with a lint-free cloth and high-concentration isopropyl alcohol.

结论

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

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 installing.

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
