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.

This battery is an exact replacement for the battery in a Logitech Harmony One remote control. No problems installing it. However as soon as your original battery stops holding a charge for a few days you should replace it. Otherwise the battery may swell to a point where you need to take apart the remote in order to remove the battery.

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.

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

Perfect and priced well. Fast delivery

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.

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.

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