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.

### ⭐⭐⭐⭐⭐ I used this to put into my Razer Nari Ultimate Headset.
*by A***W on October 15, 2024*

Works just fine, just be sure to use a soldering gun and heat shrink some wrap around the wires. I added some extra electrical tape for security and im fine with it. Battery lasts days without charging as opposed to one day and needed to charge every night. Wonderful!
