Use this guide to safely remove and replace the battery in a Logitech MX Vertical wireless mouse.
Note: If your battery is swollen, take appropriate precautions.
Accessing the battery requires removing the adhesive feet on the mouse’s underside. If thoroughly heated, they can be cleanly removed, but you may need replacement feet if one rips or some of its adhesive is left behind.

¡Excelente guia! ¡Parece haber sido hecha por el fabricante! ¡Muchas gracias!
Where can I purchase a known good new battery (OEM preferred)?
Is it actually important to replace with the same mAh value?
Or can I go with something bigger as long as the voltage is 3.7V, the connector is the same and the battery actually fits inside the mouse?
Looking for the same info as the other commenters, where can I find the replacement battery for sale and are the other ones you sell for similar logitech models good enough to replace for this one?
You can find the replacment battery here: https://www.cutratebatteries.com
Just search AHB521630PJT-04
You're welcome!
Thx for the great disassembly instructions - my mouse stopped charging, but un-plugging and re-plugging the battery did the trick.
This initially seemed to work and power the mouse but it wouldn’t charge. I tried disconnecting and reconnecting the battery as well as trying several USB sources but nothing worked (and yes, I am using the Logitech cable that came with the mouse). With the battery still connected even the option of powering the mouse with a cable stopped after a few minutes. I’m not sure if I’ve done something wrong or if I’m just unlucky but my mouse will now have to be permanently cabled which, to be honest, isn’t really much different for where I use it. It’s frustrating though, why a device like this couldn’t have just used AA batteries.
mA value not important. Only 3.7V important.
The higher the mAh, the longer it can be used, also the higher mAh, usually battery is longer or wider and heavier. A little bit bigger size and weight will not matter at all.
