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

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.

This battery is a good fit & easy to install. Unfortunately it doesn't last any longer than a 5 year old original battery. Waste of time, money & effort to replace!

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

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.

Not a lot to say. It's a battery. It showed up on time in a ridiculously oversized Amazon box (I assume because it's a lithium ion battery). It was plug-and-play with my MX Master 3 (for Mac), and seems to be working as intended. The only thing different about it compared to the OEM battery is its leads are about 15mm longer, so the wires had to be routed around a screw peg instead of making a straight shot to the connector plug like the original. Zero complaints and would buy again.

Although I now know how to quickly open my mouse and change its battery ... it did not hold a charge in my Logitech MX Master 2s more than 24 hrs and its completely dead. I am going to try to find a oem or spend a little more money ... really didnt expect this and was a total waste of my time.

Does not hold a charge very long at all. It doesn't feel like it lasts much longer than the broken/old battery I replaced. It's a relatively time consuming repair as well, so I wouldn't recommend going this route, unless I happen to just get a bad one. It needs charged constantly.

Replace the original battery with this, it is about a month that it held the charge vs the brand new Logitech that may last for a week or so .. be careful when removing the old battery, don't put sharp objects behind the battery to detach it from adhesive enclosure ...

Not a quality item like an original, does not hold charge.

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.

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

It works, but was totally flat on arrival.
