Replacement Li-ion Battery

The Cameron & Co DS-CS-AY4020CL is a 1.2 Ah lithium-ion battery built to replace the original power cell in a wide range of cordless telephones. It fits models from Uniden, Avaya, Nortel, Alcatel, Mitel, NEC, Doro, AGFEO, EnGenius, RTX, Funktel, Alinco and Jacob Jensen DECT handsets.

Compatibility Scope

This pack suits owners of the listed desk and DECT phones who need a direct drop-in replacement for part numbers such as 1000060, 690104, 10000058 or 51015404. Buyers whose handset uses a different voltage, connector or form factor should look at another battery.

Sustained Operation

Rated at 3.7 V and 4.44 Wh, the cell delivers consistent voltage across a full talk-time cycle rather than fading after a short burst. The chemistry maintains stable output during long calls and repeated charge cycles without sudden capacity drops.

Questions about this item

Which handset models accept the DS-CS-AY4020CL as a direct replacement for the original 1.2 Ah Li-ion pack?

The battery fits Uniden EXP1240 and EXP1240H, Avaya 4027 and 4070, Alcatel 8232, 8242, 8262 DECT, NEC G266, G355, G566, G955, GX266, GX566, Mitel 5610, Doro 2414, 2415, 2424, EnGenius Freesty l2, RTX 8630 and 8830, plus the listed Alinco and Jacob Jensen handsets.

Will the 3.7 V 1200 mAh capacity work in a handset that originally shipped with a lower-capacity 1000060 or 10000058 cell?

Yes — the 4.44 Wh rating matches the voltage of the original packs and the higher milliampere-hour figure simply extends talk and standby time without changing the electrical interface.

After inserting the battery, how can I confirm the handset recognises the full 1200 mAh capacity?

Charge the handset until the indicator shows full, then check the battery-status menu; it should report a capacity value at or near 1200 mAh and deliver noticeably longer runtime than the old pack.
