DC 3.7V 600mAh 602535 battery Replacement for Logitech MX Master 2 MX Master 2s MX Master 3 MX Master 3s MX Anywhere 2 MX Anywhere 2S MX Anywhere 3 MX Anywhere 3s MX ERGO Wireless Mouse AHB572535

Saved me $85 and took 5 minutes to install. My Logitech MX Master 3 has served me well for about 5 years, but recently the battery wouldn't hold a charge. This new battery was only $15 and has a larger capacity than the OEM, though we'll see what kind of battery life it actually gets. But so far, so good as my mouse is back to being able to be used wirelessly! UPDATE: Battery lasted about 2 months of daily use, never being turned off. Recharged perfectly.

My Logitech MX Ergo trackball's battery started not providing power even with the trackball plugged in. I have using it like this for 3 months, finally it bite the dust. So I ordered (what I thought) a brand new trackball. It was a renewed item, it is working good. I replaced the old battery in the old trackball, so far it is being charged up, will be using the old trackball with the new battery on my Alienware MX-18 laptop.

I bought this battery for a l.ogitech MX Master 2S. It was easy to replace, however, the battery does not last very long. I charged the battery fully, but only lasted a week before losing charge. I do not use my desktop very much. With the original battery, my mouse would hold a charge for months. Now with this battery, it only seems to last a week. I would buy a better quality from someone else.

Perfect fit for a 2017 MX Master. Mouse runs fine and charges fine with this replacement battery. I also tested the discharge capacity, and it measured 528 mA*h, 1.76 W*hr. See discharge curve. Since I tested 4.1v (open-circuit) to 3.0v (discharge cutoff) which is roughly 90% of capacity, the full capacity is probably meets the advertised 600mA*h. 0.2A (~1/3C) discharge rate. Custom source-measure unit, calibrated against a Fluke 79 III. You'll need some tape to mount the battery in its tray. I used a cut piece of phone-battery peel-tape... if this mouse survives to need another battery replacement in another decade... Fun fact: the original battery it replaced tested at 183 mA*h, 0.59 W*hr.

Title says it all - perfect fit on this device. Not too hard to install, you just need a Torx #6, some case pry tools, and steady careful hands. The wiring & connector is perfect fit too. Is it as good as the OEM battery? Only time will tell how good the battery life is, and how many recharges it lasts before it gets tired. Update: the red battery LED has started to blink; not all the time, but intermittently, so it's nearing the end of its first charge. That makes about 6 week battery life, which is 2-3 times longer than the old tired battery and close to what it had when new.

To replace the battery in MX Master, you need to remove the side pads to get to 4 screws, as well as 2 visible small torx screws. Once the screws are removed, it's easy to replace the battery, and this was a perfect fit. I'm 2 years down the road now, and back to very short battery life. I get just a few days before the <10% warnings are popping up, and I have to plug it in frequently. I'm leaning to MX Master 3 instead of replacing the battery again. Not 3S - all my dongles are Logitech Unified - I don't want a mouse that's breaking away from being compatible with my existing investments. Not sure though if the claimed 70 days will hold up so long - the MX Master claimed 40 days, it's nowhere near now. I don't mind a new mouse now and then, but Logitech mice are not cheap. Wish they were less of an ongoing money sink or that the battery was readily replaceable with one that lasts as well as OEM.

This battery so far has been performing better than expected. The fit is perfect, the connection is perfect, & the charge/drain cycle outperformed the original battery. Sometimes it really amazes me how a company (Logitech) can make an exceptional product, and with the same stroke of genius, cripple that product by trying to save a few coins. If they used a better grade of battery, (Logitech) they could have avoided a lot of headaches for customers, most people will buy another mouse because it is that good. But once they come across reviews of how cheap it was to replace the battery. I hope they write the company and demand a refund for buying a new mouse. Because the old one now refuses to keep charge. So you buy new, or use the old one as a wired mouse forever. Thank you for providing the battery information as well, Logitech made it very difficult to figure out.

I was able to bring back a Logitech MX Master mouse back from the dead. Install only took a couple minutes and now the battery lasts longer than it did when the mouse was new. If you’re going to be swapping out the battery on an MX Master, I suggest buying new feet as well. You’re probably going to trash the existing feet trying to remove them, and having slick new feet is just another perk along with a new battery. Fits just like the old battery, but cost way less than a new mouse.

Hat in meinen 7-jahre alten Trackball super gepasst. Aufgeladen und nun läuft das Teil wieder super. Lieferung von Amazon innerhalb 24 h, perfekt.

マウスのバッテリーが劣化して、充電されない状況となり、購入。バッテリーの交換は非常に簡単だし、交換してからのバッテリー持ちも、全く問題なく一か月近く過ぎました。ただ、バッテリー交換の際、マウスの上下を分離して開けなければいけないのですが、止めてあるネジが裏面の四隅に貼ってあるシールをはがさないと、外せないので、同時に交換用のマウスソールも購入しておいた方が、よいですね。

Great product! works perfectly with the Logitech MX Master 3. Recommend by a set slider for the feet as the screws are below them. Also very quick delivery.

If my MX Master 2S wasn't teal I'd have thrown the thing out long before coming across this and replaced the whole mouse instead of just the battery. Took 5mins to replace and my battery life went from 5-7 days to 4-6 weeks with daily use. Easy to install (follow a YT vid), perfect fit, just feels like new again. Going on six months and no change in performance.
