Logitech MX Master 3S Battery Replacement
Introduction
Use this guide to replace the battery in your Logitech MX Master 3S mouse.
Lithium-ion batteries have a limited lifespan. If your mouse dies quickly, it may be time to replace the battery.
If possible, follow this guide after your battery has fallen ***below 25% charge***. While your MX Master 3S has a relatively small battery, handling any charged battery is a potential safety hazard.

Conclusion
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.
***To reassemble your device, follow these instructions in reverse order.***
Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
