Replacement battery for Logitech diNovo

This Cameron & Co DS-CS-LOM50RK lithium-ion cell replaces the original battery in Logitech diNovo Edge, diNovo Mini and Y-RAY81 keyboards. It matches part numbers 190304-2004, F12440071 and M50A. The pack delivers 3.7 V and 950 mAh for 3.52 Wh of capacity. Builders restoring a compatible keyboard can install it directly.

Thermal behaviour and power draw

The lithium-ion chemistry provides stable voltage during normal typing use and holds charge well when the keyboard sleeps. No active cooling is required and the cell adds no audible noise. Power draw follows the keyboard's own wireless transceiver duty cycle.

Supplied accessories and fit

The single white battery measures 53.04 x 33.24 x 7.28 mm and weighs approximately 50 g. No tools, cables or software are included in the package. Buyers who need a multi-cell pack or a different voltage should look elsewhere.

Questions about this item

How do I install the DS-CS-LOM50RK battery into my diNovo Edge, and which step causes problems?

Open the keyboard's battery compartment, disconnect the old pack's connector, then plug in the new 3.7V 950mAh unit ensuring the white housing sits flush; the step often missed is fully seating the connector before closing the cover.

What maintenance or replacement will the DS-CS-LOM50RK need over time?

The Li-ion 3.52Wh cell gradually loses capacity; after hundreds of full charge cycles run-time becomes noticeably shorter, at which point you simply swap in another DS-CS-LOM50RK.

What limit appears first during sustained use of the DS-CS-LOM50RK?

The 950mAh capacity sets the runtime ceiling; under continuous load the 3.7V cell will deplete before any thermal or voltage threshold is reached.
