602535 652535 Battery 650mAh Replacement for Logitech MX Master 2 MX Master 3 MX Master 2s MX Anywhere 2 MX Anywhere 2S MX Ergo M-RO052 Wireless Mouse 910-004362 910-004374 533-000120 533-000121

If you saw my review of the replacement mouse pads/feet for my Logitech Master S mouse, I also decided to upgrade the internal battery. My older of two mice was losing the length of its charge. I replaced the old battery with this new battery. It fits perfectly and went in smoothly, neatly fitting into the available space (search for replacement instructions on YT). I am getting MUCH longer battery life at long last. The connector fit perfectly into the plug with the exact wire length to prevent too much coiling. This battery is the compatible replacement part and showed in an installation that took about five minutes. This was an inexpensive way to add life to a very expensive and adored mouse.

Does not hold a charge any longer than the 12-year-old battery I replaced. I'm guessing it isn't truly 650mAh. I'm requesting a refund. I got it 3 weeks ago and I've already had to charge it twice.

Installation was straight forward and it worked right away. I purchased this back in June and am still at 2-dots (not sure the percentage). So, the battery life appears to be phenomenal. I'm so happy I did this cheap fix rather than buying a new $100 mouse. I am a bit concerned about the longevity of the battery given it's a roughly the same size as the original battery, has a higher capacity than the original, and the original died after a couple years. But, until that fear comes to fruition, 5-stars all around.

Perfect solution. Still using this mouse -- been 7-8 years now.

This battery replacement is a total failure. After a week of use it has failed to hold a charge.

Had to recharge after two weeks. After two months, it’s dead and will no longer hold a charge. I have to keep my ergo mouse constantly plugged into the USB charging cord.

Not fit for my skybell slimline II ringbell, so returned

Good replacement- worked on my Logitech MX anywhere 2S mouse

Passt als Ersatz für einen defekten Akku für einen Logitech MX Ergo Trackball. Der Trackball muss allerdings auseinander geschraubt werden. Kein Hexenwerk...

UPDATED Battery was fitted on the 20th, MX Anywhere 2S showed good battery life for about 20 days, then died. After 5 hours charging Logi Options+ showed battery life was still critical\not charging & lasted about 10 minutes. I expect I'll have to get another set of mouse feet too. Original Review Bought this after my Logitech MX Anywhere 2S Computer Mouse needed charging every 30 hours or less. The replacement battery is still holding a high charge after a week as reported by Logi Options+ software. Fitting is as easy as peeling back the feet removing 4 screws underneath & fitting the new battery. **HINT** Buy a set of Logitech MX Anywhere 2S Computer Mouse Skates Stickers to replace the feet, mine came apart during disassembly.

It works, but was totally flat on arrival.
