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.

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.

I began to have issues with the battery life on my Logitech Anywhere MX3 Mouse about 8 months after I got it. I was very happy with it's performance but I was beyond the time for a return or warranty. Even though the instruction booklet for the mouse says the battery is not replaceable by the consumer, I watched a video tutorial and decided to try it. When I received the battery I carefully made the replacement and the mouse has been working great ever since. I have a separate, unrelated problem with the charging port but I'm still able to charge the battery fully every time.

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.

I have used my Nextbase 522gw dash cam for years. Suddenly I noticed all of my settings were reset, and each time I reset them back to the correct/wanted setting I would then again realize it was reset back to factory settings after each time I turned off my car. After some searches online I found out that the internal battery (350mAh 3.7v) had failed, and as such would not keep those settings nor allow the dash cam to "wake up" if the car parking feature was triggered. As such some videos on you tube showed users installing larger batteries. I wanted the same, so I ordered many batteries, and found that this one would still "fit" and offered a larger capacity. I had to remove the adapter, and carefully solder on the wires to the old wires. Disassembling the dash cam was easy after watching videos, installing the battery was a little cumbersome, but ultimately fit and is working great as I wanted. The manufacturer apparently expects the connection to be removed, as the battery also came with a small piece of heat-shrink tubing, which I cut and used for all three connections. The battery capacity is either over-stated, or is from poor materials, as other reviewers stated - the battery simply does not perform as expected. With that said, the battery works better than the old one that I replaced and that's all that matters to me. I hope it will last more than year. Only time will tell.

This battery is almost exactly the same dimensions and quality as the factory battery in my MX Master 3s. It was an easy installation and there were no issues whatsoever with the battery dimensions or the plug. The life seems comparable to the factory battery. The pack was shipped at a nearly perfect 3.8v per cell, meaning that the manufacturer took the time to put the pack at storage voltage for shipping. A small detail, but it gives me confidence in the attention to detail of the manufacturer. A great replacement for if your battery fails on the Logitech MX Master 3s.

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.

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

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.

Very good battery

Llegó 5 días después a la ciudad de México. Llegó en una bolsita genérica con un accesorio para cortar los cables y cambiar la polaridad. No fue necesario. La batería es nueva, idéntica a la original. Tengo este MX Master 2s de Logitech desde el 2020, ahora en 2024 fallo la carga de la batería pero con este repuesto, sigue funcionando como nuevo.
