My Harmony One remote wasn't staying charged for long. Discovered, similar to other users, my old battery had swelled quite a bit. Had to use needle nose pliers to pull it out. New battery slid right in, no issues at all. Had to resync the Harmony One to update time and date ranges. Channels and Devices remained fine, even though it sat without any battery for a week.. Battery works significantly better than my 10 year old one. Recommend and perfect fit for a Harmony One. NOTE: As other users asked in Q & A, why so long to get? I had ordered a different battery (less money), and even with Prime, four days in, had not shipped. Canceled that order, ordered this battery for $3 more and it arrived two days after my order. Installed within an hour of it's arrival

Fit perfectly. No loss of programming when doing a quick battery swap. Old battery was good for about an hour at most. New battery lost only1/4 of charge with use and 10 continuous hours off of the charging cradle. Works for me!

It’s got everything. Quality, easy to use, speed, value and works perfectly in my universal remote control. Very happy.

It fits our remote and works as it should but the battery life isn't great. We had another generic battery before this one that held a charge for a few weeks at a time and lasted several years. This one has to be charged weekly so I don't think this one will make it in the long run.

I thought I was going to have to replace the Logitech universal remote,. I initially contacted to Best Buy where I purchased the remote, but no one would give me an answer as to why it stopped working when it plugs into an outlet to charge. Turns out there is a backup battery inside the device. I looked it up on Amazon and one day later it arrived and the remote works like a charm.

We needed a replacement battery for our Logitech Harmony 900 remote. Battery was a perfect fit and installed easily. Note: After installation, during first use: it caused the blaster (box that receives remote signal) to become unsync’d from the remote. We uninstalled and reinstalled one component function on the remote (AppleTV) which prompted the remote to resync. May or may not happen to you. Just passing along what we had to troubleshoot. Battery itself is great!

The old battery was the original one that came with my 14-15 year old Logitech remote control. I knew that it died a few months ago when it wouldn't take a charge and the remote control stopped working. Since the remote was so old I did not have any hope for a replacement battery but I was pleasantly surprised to find that it is still available. The new battery came charged and I was able to use the remote right away. I had been dreading that I might have to buy a new remote control and would have to reprogram it to work with all the video/audio components all over again. Well, I did not have to! Thanks to the new battery! It brought a new life to the old remote!

Operates exactly as expected. It's a new battery and makes my remote act like new.
