Compatible replacement battery

The Cameron & Co DS-CS-AYD3CL is a 2.4V 600mAh Ni-MH battery built for Avaya C4065R, Nortel, Tenovis Integral D3 Mobile, Aastra Openphone 28 and related handsets. It replaces original part numbers 4.999.134.298, 4999046235, NTTQ49MAE6 and CS-AYD3CL across multiple brands. The black pack measures 35.49 x 33.45 x 6.08 mm and fits the listed devices without modification.

Upgrade from depleted original cells

This unit replaces a factory-fitted Ni-MH pack that no longer holds charge after extended use. The jump is worth it when talk time drops noticeably or the handset fails to stay powered through a typical shift. It restores the original 1.44W h capacity without changing voltage or chemistry.

Capacity and runtime headroom

The .6Ah rating delivers the same energy budget the handset was designed for, supporting normal office call volumes and standby periods. Runtime scales with the phone's own power draw, so heavy continuous use will drain it faster than light intermittent use. It does not add extra capacity beyond the OEM specification.

Questions about this item

Will the 35.49 x 33.45 x 6.08 mm size fit my Avaya C4065R handset battery compartment?

Yes, those dimensions match the original pack for the Avaya C4065R and listed compatible models.

How do I install the DS-CS-AYD3CL and what step do people miss?

Open the battery cover, unplug the old connector, plug in the new pack observing polarity, then close the cover; the step often missed is fully seating the connector before snapping the cover shut.

When will the 2.4 V 600 mAh Ni-MH pack need replacement?

Expect roughly two to three years of typical cordless phone use before capacity drops enough to require a new battery.
