Replacement battery for Avaya Ascom DECT handsets

The Cameron Sino DS-CS-AYD810CL is a lithium-ion battery rated at 3.7V and 1100mAh. It replaces the original 1220187 and 660273/1B cells used in Avaya 3700 EX, DECT 3740 and DECT 3749 models. The pack also fits Aastra DT413, DT423 and DT433 series handsets as well as Ascom D61, D65, D81 and DH5 units. Office users who need a direct OEM-compatible power source for these specific cordless phones will find it suitable.

Simple drop-in installation with correct orientation

The battery slides into the handset compartment and connects via the existing plug; no soldering or tools are required. Align the connector carefully because forcing it the wrong way round can damage the pins. The black casing matches the original appearance and the 73.60 x 43.50 x 11.00 mm dimensions keep the handset profile unchanged. Buyers who expect a larger capacity than 1.1 Ah or a different voltage should look elsewhere.

Verify the handset model

Confirm that the device label shows one of the listed models such as 3740, 3749, DT413, DT423, DT433, D61, D65, D81 or DH5. Cross-reference the old battery sticker for part numbers 1220187, 660273/1B or CS-AYD810CL to ensure an exact match. The pack is supplied as a single unit and is not intended for phones outside the compatibility list or for applications requiring a different chemistry.
