1050mAh/3.7V Li-Polymer Replacement Battery for Logitech Harmony Ultimate/Logitech Harmony Touch 533-000084 / Logitech 915-000198

I love my Logitech remote, but Logitech doesn't support them anymore, and there are no comparable remotes on the marker these days. After over a decade of use, its battery finally died, and I was worried that I was going to have to buy a replacement remote that was worse than what I was replacing. Happily, I got pointed to this battery via a YouTube video. Replacing the old battery was a bit tricky as the remote was hard to open and the old battery was glued it, but I was able to get the job done. Despite the fact that the original battery was rated at 1100mAh and not 1050mAh, this battery is working just fine and has given new life to my old remote. I've been using it (and recharging it) for several weeks now with no issues at all.

Saving grace since logitech quit making this Harmony remote. Difficult to get the old one out due to glue but the replacement worked fantastic.

Battery was about as bad off as the one I replaced. It's short lifed and requires charging on a daily basis.

Fit my Logitech Home Harmony Hub setup perfectly.

It's been on the shelf for years, or so it seems. The replacement battery was almost in as sad of shape as the one I replaced.

I bought this to replace the battery for my customer’s Harmony Elite. A quick and easy easy swap, but you gotta be careful. Find the video on YouTube that shows how to do this, there is a link to the product to make sure you get the right thing.

Once the battery got here it worked great in my remote. It did however get stuck at customs for several weeks and it didn't look like it would arrive. If you need it by a certain date I wouldn't count on the estimate.

I bought a cheap set of electrical pry tools on Amazon (Kaisi), watched a good YouTube video on how to do it, and did the replacement easily. This will extend my devices usage another 2.5 years. love it.
