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.

Fit perfect. Took one star off because the connector is wrong for Jabra evolve 75. Had to cut connector off of both batteries and install the smaller Jabra connector onto the new battery. It came with enough heatshrink to cover the solder joints where I connected the wires from the smaller connector used in the Jabra. You have to know what you are doing here because this is a live LIPO battery you are cutting leads from and soldering to. I found instructions online how to get to the battery on the non boom mike side of the headset. Used thin double sided tape to hold it in place while re-assembling the Ear Cup. Doable but not plug and play as stated above. I will do it again when the time comes.

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.

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.

Works well in my project. Seems like a direct replacement for the old battery that eventually died. Same size and shape, which is good because there is no extra space for any variations in size.

Worked as needed. No issues. Same as original.

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.

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.
