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.

Most rechargeable mouse batteries last several months up to a year. This battery needs charging every week. “Junk”

Amazing battery: the battery that comes from the factory in your keyboard is only half of the capacity of these. I use my keyboard wirelessly for at least 14 hours a day, and after installing this batter,y my keyboard now only needs to be recharged once a week. If you use it less and turn off the RGB you could probably get 2-3 weeks of use out of this battery.Installing is also very simple. Here are the instructions:1. On the back where the sticker is (S/N and all that), peel back the lower half of the sticker.2. You can use a heat gun to make it peel back easier if you don't want to ruin the sticker.3. Underneath the sticker you'll find 2 screws, simply remove those and the plastic piece slides out.4. Uninstall the old battery and plug in the new one; make sure the connector has a snug fit.5. Put everything back, then turn off the keyboard (with the switch) and turn it back on.That's it!

Works on a Gpro Superlight

Not fit for my skybell slimline II ringbell, so returned

Fits and works very well, saved my Logitech Presentation which battery died due to discharged.

Got this battery for Logitech K800 keyboard. It appeared to be correct battery, but the wire leads were too short. It has 6" leads, but the original battery had 7 1/4" leads. So the new battery would not fit the proper location. I modified the battery using the leads from the old battery and finally got it to fit.

I bought this battery for my 10-key G915. The original battery died in the first 6 months or so. This replacement worked well for about 3 months, but I needed to plug it in to charge way too frequently. Now, if I unplug the power source, the keyboard dies instantly, as well as random deaths mid-use, even when plugged into power. Now I cannot tell if my keyboard is bad or if the batteries are just horrible.
