Introduction
Use this guide to replace a worn-out or dead battery in your Logitech G502 Lightspeed.
If you plan to reuse the mouse feet, you’ll need to apply heat to loosen the adhesive and remove the feet with minimal bending. Bent or torn mouse feet may require replacement.
If the 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.
You might need replacement adhesive to reattach the new battery. Check the guide and your replacement battery in advance.

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 if the battery comes without one. Press the new battery firmly into place.
To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
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%.
Take your e-waste to an R2 or e-Stewards certified recycler.
