Review: Fits in Logitech Pro X Headset (soldering required) - Worked so well I had to come back to write a review. I replaced my Logitech Pro X Headset battery, the hours til dead are now double. I admit the connector wasnt the correct one so it will take some basic soldering skills to steal the old connector and replace it on the new battery. Very happy with purchase
Review: Worked for MX1000 - I needed replacement batteries for (2) Logitech MX1000 mice. The OEM batteries were in a protective case, while these have a protective wrap. The fit was good within the battery cover, but I did have to add some doubled sided tape. Otherwise the battery could move back and forth within the battery housing. Install was easy enough and the batteries were charged upon arrival. The price was fair enough and both batteries worked. Time will tell how long they last. The OEM batteries were 15+ years old and would only last for a few hours of use.

### ⭐⭐⭐⭐ Replacement battery
*by M***N on July 30, 2026*

Installed this in one of our iRV3 brake system components (transmitter). It fit fine, but we had to alter the wiring hook-up to connect. So far, it is working ok. Note: an exact replacement for the original battery was hard to find and this was the closest option.
