Use this guide to replace the battery in your Logitech MX Anywhere 3 for Mac 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 Anywhere 3 has a relatively small battery, any charged battery is a potential safety hazard.

Hi,
Thanks for the tuto.
Do you have a link to where I could buy the battery?
Thanks,
Louis.
Hi Louis, we checked for you and can confirm that this battery is compatible with your mouse: crwdns2937315:0IF362-136crwdne2937315:0. Make sure to buy just the "Part Only" option, since we don't currently sell the rubber feet for this mouse. Keep your rubber feet intact so you can reuse them during reassembly. Good luck with your repair!
