Replacement Battery for Avaya DECT Handsets

The Cameron & Co DS-CS-AYD420CL is a lithium-ion battery built to replace the original power cell in Avaya FC4, D4 Office, DECT D4 and IH4 handsets. It also fits Tennovis Integral D4 and Mobilteil IP65 models. The pack restores talk and standby time for office and medical DECT phones that use part numbers 5010808000 or 5010808030.

Capacity and Voltage Constraints

Rated at 3.7V and 700mAh, the cell stores 2.59Wh of energy. This capacity fixes the maximum runtime between charges; users needing longer shifts must recharge more often or keep a spare. The nominal voltage suits the handset's charging circuit, so no adapter or firmware change is required.

Physical Fit and Daily Handling

The silver casing measures 52.74 x 40.60 x 10.20 mm and slides into the handset's battery bay without modification. Its exact footprint matches the OEM pack, so the battery door closes flush and the handset retains its IP65 rating where applicable. The 100% OEM-compatible design means the contacts align first time, avoiding the intermittent connection issues common with ill-fitting third-party cells.
