My mom has 2 remotes and I have one. She uses her remotes heavily while I use mine very sparingly. She has been getting about 3 years of battery life with her use and charging while I have been getting more like 4 with my light use and charging.I may try a different brand next time to see if a higher priced on makes a difference in battery life. The original Harmony One battery seemed to last much longer. But, it's been years now, so I can't remember how long I had it before needing to replace the battery.

No issues with my Harmony 720. It's holding charge and charging with the original charger. Revived the old remote for a retro gaming setup.

This battery works well and has a perfect fit in the Harmony One remote. Some of these batteries you buy require a little shim to keep them seated tightly. But from a full charge, it only lasted a couple of days with light use, where I would expect closer to a week. But that's good enough to get by and it was a low price. Don't know how long the overall life span will be since I've only had it a week or 2.

I replaced old battery with this new fully charged (by me) battery on 9/27 into my Harmony remote. It sits out and is used during exercise, not recharged after each use. Today (10/12) the indicator dropped to 2 bars of the 3. Since I was done for the day and since I don't like it below 2 bars, I put it in the charger for tomorrow. That is two full weeks to an indicated half charge, and I am pleased. At this short use point in its life, I like it.

Bought this battery to replace the one in my Harmony 720 remote.It fits perfectly and charges with no problem. With my previously battery in the remote, it only charges 2 out of 9 times I placed it in the charging dock. I originally thought it was a contact problem. But after replacing it with this battery, it charges every single time I placed the remote on the charging dock.So far it works very well, and there is no heating issue with the battery.I cannot evaluate the battery capacity because for remote, you just use it a few times and place it back on the charger. I wouldn't expect it to be of the same capacity as the original, but it works just fine.

I purchased this to replace the battery in my Logitech Harmony One remote control. It barely lasts two days at a normal use level. My previous battery lasted well over a week with the same usage patterns. Even at 3 years old my previous battery lasts longer than this one.

I have a very old Logitech Harmony One remote that had the bloated battery (not holding charge very long, weak signal, etc) issue. I was able to get the battery out without taking the remote apart, although it was touch and go there for a bit. I found it best to pry a small screwdriver under the battery and pull with needle nose pliers at the same time. This battery slipped right in (amazing the thickness difference between stock bloated and this one) and was about half charged from the factory. The remote charged to full in a few hours and so far, has kept charge quite nicely.

Good replacement for an old battery on a Harmony One remote. Charged up quickly and works well.
