Use this guide to replace the battery in your Logitech MX Master 3 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 3 has a relatively small battery, any charged battery is a potential safety hazard if accidentally bent or punctured.
