Review on 📺 Enhanced Replacement Remote for TCL Roku TV with Netflix, Sling, VUDU, and Hulu Shortcuts - Ultimate Convenience for your Viewing Experience by Ricardo Fast

1.5V AAA batteries (NOT 1.2V AAA) must be used, otherwise the device not working. This most likely applies to all remotes, not just ROKU. I tried using a couple of "rechargeable" 1.2V AAA batteries I had on hand, but they didn't have enough energy to power the remote. Actually, the battery pack is a far cry from using 1.5V AAA batteries. Note 1: Most batteries are 1.2V. Note 2: 1.5V batteries are only now on board, but they are slightly more expensive.
