Compatible Avaya DECT Handsets

This Cameron & Co lithium-ion battery replaces the original power pack in Avaya FC4, D4 Office, DECT D4 and IH4 handsets as well as the Tennovis Integral D4 and Funkwerk DECT FC4 Medical models. It matches the 3.7V 700mAh 2.59Wh specification and fits the 52.80 x 41.00 x 9.60 mm cavity. The black cell is brand new and 100% OEM compatible.

Replaces OEM Part Numbers 5010808000 5010808030

The cell directly substitutes Avaya, Funkwerk, Tennovis and Mobilteil part numbers 5010808000 and 5010808030 without modification. Upgrading is worthwhile when the original pack no longer holds a full shift charge or shows swelling. It restores the rated 0.7 Ah capacity for DECT voice and IP65 handset duty.

Sustained Talk-Time Delivery

Lithium-ion chemistry maintains a stable voltage curve across the discharge cycle, so talk time remains consistent until the handset signals low power. The 2.59 Wh rating supports extended roaming sessions on DECT networks. No memory effect means partial recharges between shifts do not reduce usable capacity over time.

Questions about this item

Will the 52.80 mm by 41.00 mm by 9.60 mm battery fit the Avaya Integral D4 handset?

The battery measures 52.80 mm long, 41.00 mm wide and 9.60 mm thick, matching the original compartment in the Avaya Integral D4 and compatible models.

How do I install the Li-ion pack without damaging the connector?

Align the polarity marks, press the plug straight into the socket until it clicks, then tuck the wires flat so the battery cover closes without pinching them.

When should I replace the 700 mAh 3.7 V pack?

Replace it when talk time drops noticeably below the original runtime or the handset shuts down unexpectedly during a call.
