I bought them because my wife likes the logictech K750 Solar keyboard and they never get enough light to keep the batteries charged. So eventually the battery dies and the keyboard is useless. So far, in most cases, replacing the battery, although logitech does not officially support it, bring the keyboard back to life. At least until it is time for a new battery again,

This battery did not hold a charge just two weeks after I installed it in my keyboard. I started turning the keyboard off every time I stopped using it to conserve the battery life. After reading other comments, I guess I'll try giving it direct sunlight to see if that helps the problem. I didn't have this problem with the original battery and definitely wasn't expecting problems this soon with a brand new rechargeable battery.

Great item. I like that it is a name brand (Maxell) and not generic. Works well, has a variety of uses. Costs much more in stores!

Logitech orphaned their wireless, solar-charging K750 keyboard some time ago, so these ML2032 batteries are no longer easy to find––and Logitech is no help either finding them or telling you how to switch one out of your keyboard if you do find a replacement. However, replacing them with regular CR2032 batteries, which are available everywhere over the counter, isn't ideal because those kind aren't rechargeable. I don't know how long non-rechargeables would last in this keyboard, or if they would overheat with the trickle current of the photovoltaic cell constantly trying to charge them. So, if you can find the ML2032 online, and need it for your device, you should probably do as I did and buy two. They have a long shelf-life. And they get the job done without any issues. Fortunately, there is also a YouTube that will show you how to switch out the battery without damaging the keyboard.Read full review

I desperately needed a battery for a K750 Logitech Keyboard. It would always show red and sad face on the keyboard, I popped a new battery in the back, paired it with the new USB, and it works great! Totally worth the price!
