3.7V Rechargeable 70mAh Li-ion LIR2032 Battery/ 2pcs as a Set

I have 2 Logitech K750 solar keyboards. One has run at work for 5 years and is still going. However, with COVID19 I have been working from home and the battery in my K750 at home would not stay charged with the added use. I replaced the battery with a Maxell identical to what came out of the keyboard, but it would not hold a charge for more than a few days, as has been reported by others in their reviews. I, though the keyboard was done for and in fact replaced it with a cheapish keyboard from Amazon. However, the key positions and tactile actions were a little different and I was mistyping every second word. In desperation, I bought this LIR2032 battery and tried again to resuscitate my keyboard. This battery has been fantastic! It came fully charged and has remained at 100% charge for 2 weeks now. The light from the monitor is sufficient to maintain full charge. according to the Solar App. I am thrilled to have my monitor back in action again.

I bought this battery as a replacement for a Logitech K750 keyboard (Mac). I initially bought a Maxell ML2032 rechargable battery, but that particular one was perhaps a dud. Reviews for that battery were terrific, but the one I got failed to charge well, and wouldn't hold a charge. After reading several more reviews I opted to switch to this LIR2032 instead and the results are outstanding. It was at 100% out of the package according the the Solar App (the other battery was nearly dead when it arrived), and after a few days it's still at 100% with minimal light and moderate use. The other battery took days to charge to even 80% (never going higher), and would drain very rapidly. Pleased with this replacement and would recommend for this keyboard application.

I replaced ml2032 with this cause the battery kept dying overnight. It works great. Now my wind sensor stays power all night till the sun comes up to recharge it.

I have two k750 keyboards (one for windows, one for mac). Both original ml2032 batteries were toast. First off, the battery life reported by the Solar App is now bogus, as these typically got from 100% to non-functioning. Even if I let these "soak" directly under a lamp, I can only get about a day or two of usage out of them before they are entirely dead and need another "overnight soak" to work properly.

Have old beloved Logitech K750. Choice was between this replacement battery and original Maxell - but other reviews indicate that Maxells are no longer made and thus available batteries can be quite old by now and a real crapshoot. These are new. Popped in and keyboard is charging right up. Highly recommend.

I just love this Logitech keyboard, and was dismayed when after many years the rechargeable battery died. I was even more dismayed to find a yellow warning label on the dead battery telling me not to replace it. Really. I replaced it anyway with this this product, and now the keyboard is as good as new. Fast service, good product, good price. What's not to like?-I rather think that I'll replace the old battery in my car, rather than buy a new car; what CAN they be thinking?

These are the correct batteries to use with the Logitech K750 keyboard after the original battery dies. Popped one in my keyboard and after 30 minutes of charging was back up and typing again. Be warned that you only get a few chances to get the battery carrier out of the keyboard before it breaks, so best to get it right the first time.

Bought these to replace Garmin battery. On the positive side they are compatible and the Garmin fired right up, and they can be recharged.On the downside, out of the box (bag) they are lasting less than an hour before need of recharge, and will most likely be toast soon.
