Works perfectly as a replacement battery for my Logitech Harmony universal remote.

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.

Does battery stuff.

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.

This will renew your Harmony Logitech universal remote. Easy install and has been just fine for months now.

After a week or so, the battery wouldnt last for more than 2 days, even with minimal use. My guess is since the Harmony remotes these are made for are no longer manufactured, these have probably been idle in storage for a long time. I ended up tossing all my Harmony remotes away and went with a universal remote, that's actually a couple of bucks more than one of these batteries. Sure I have to do a few more clicks, but everything turns on and off as expected. best part, no more dealing with rechargeable batteries.

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 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.
