Logitech L-LY11 Remote Control Battery Specifications

Although Logitech remote controls are optimized for range and energy conservation, the Li-Ion chemistry in your battery will eventually wear out and need to be replaced. To get the same performance time out of your Logitech L-LY11 remote when it was brand new, you will need a replacement battery with a capacity around 600mAh (milliamp-hours).
