Logitech K750 Wireless Solar Keyboard for Windows Solar Recharging Keyboard 2.4GHz Wireless - Black

You know. A friend of mine has this keyboard! It was WONDERFUL! I loved the heft, the design, its being solar. Its been a month and eleven days. The battery per manufacturer boasting is supposed to last three months in utter darkness. It does not. Its had to be charged twice since I bought it. It stops working when the battery is at 30%. Even with the maximum amount of light it can accept to charge, it takes it THREE. DAYS. to charge back up, WITHOUT BEING USED. Mine wont even charge back up to full! It stops charging at 92% and wont consider going up past that, even when left alone to charge for an additional day solid. I understand it turning off at 30% because if a battery gets lower than that, its bad for it, but it is still INFURIATING to have bought a keyboard explicitly for long battery life and being a bit greener, and done everything you can short of deciding to sit under an INDUSTRIAL GARDEN GROW LAMP ALL DAY and the product doesnt deliver as it says its supposed to. Update 6/11/2018 - I contacted Logitech for a replacement, and they sent one gladly. It seemed to work great for a while, but after two months it too seems to have broken. The second one is now not charging correctly.

My first K750 lasted several years before it was dropped to the floor and shattered all over the place. My bad. I purchased a replacement 18 months ago and the battery is dying even as I try to type this. The battery is replaceable, but it is a PITA to get it out of the keyboard and then there is this little sticker that warns "do not replace the battery". So we are supposed to send a $50 keyboard to the landfill instead of replacing a $5 battery. The product description, however, says the battery life is "infinite". No. Poor design, poor QC. So I bought replacement batteries. Not CR2032s like what you can find in a corner store, those will not work. Needs to be ML2032 or LiR2032 rechargeable types and after reading about the ML2032s, I went and bought the LiR2032s. I like the layout and feel of the keyboard itself, but really have to question whether Logitech is still the industry leader that they once were. UPDATE 3/23 The LiR2032 is the correct battery to use. You only get a couple of chances to get one installed before the battery clip breaks apart, though, so be sure to get it right the first time. Changing out the battery did in fact return the keyboard to functioning again.
