Harmony remote batteries

The battery life in the Harmony remote will vary depending on usage. As your Harmony replaces all of the remotes in your home entertainment center, it is doing the work of multiple remotes which can drain batteries at a faster rate than a single device remote.

Harmony will retain all of your device and Activity information when replacing your batteries.

Harmony Pro, Elite & 950

The Harmony Pro, Elite and 950 remotes use one rechargeable lithium ion battery. If you're looking for a replacement, one can be purchased in the Logitech Spare Parts store (in the Batteries section).

Harmony recommends keeping your remote in the charging cradle when not in use. This will ensure the batteries stay full and will help avoid misplacing the remote.
