Purpose-built replacement battery

The Cameron & Co DS-CS-AYDH4CL is a lithium-ion battery designed for Avaya 3725 and Siemens CUC325 DECT handsets. It also fits Alcatel omnitouch 8118 and 8128 models plus Ascom D62 and Innovaphone IP62 and IP63 units. The pack delivers 3.7 volts and .9 ampere-hours for cordless phone users needing a direct OEM substitute.

Sustained talk and standby performance

Rated at 3.33 watt-hours the cell maintains voltage through extended conversations and long idle periods on DECT base stations. Lithium-ion chemistry avoids memory effect so partial recharges do not reduce usable capacity over time. The black housing matches original equipment aesthetics while meeting the power profile of the listed handsets.

Verify handset model and connector fit

Confirm your handset appears in the supported list such as 3725 DECT DH4 WH1 or OpenStage WL3 before ordering. Cross-check the original part number against 660190 R2B 660217 or 3BN78404AA to ensure electrical compatibility. The physical dimensions are 72.88 by 45.35 by 10.00 millimetres so the battery compartment must accept that footprint.

Does the 3.7V .9Ah Li-ion cell run warm during a full day of DECT calls?

The 3.7V 900mAh battery is designed for Avaya 3725, Siemens CUC325 and Alcatel handsets; normal operation stays within typical Li-ion temperature limits for cordless phones.

It replaces the original pack in Avaya 3725 DECT, DH4, WH1, Siemens CUC325, OpenStage WL3, Alcatel 8118 and 8128, Ascom D62 series and Innovaphone IP62 and IP63.

Will the 72.88 x 45.35 x 10.00 mm form factor seat correctly in my older Ascom D62 or Innovaphone IP62 handset?

Yes — the dimensions match the OEM packs listed for Ascom D62, D62 DECT, i62 variants and Innovaphone IP62, so the battery slides into the existing compartment.
