Direct replacement for Cisco CP-7921 handsets

This Cameron Sino battery matches the original 74-4957-01 and 74-4958-01 part numbers for the CP-7921, CP-7921G and CP-7921G Unified models. It is a brand new Li-Polymer cell rated at 3.7V and 1200mAh, supplied as a single grey unit.

OEM-compatible form factor drops in without

The pack measures 83.90 by 52.70 by 7.80 mm, matching the factory dimensions so the handset battery door closes normally. No extra cables, adapters or firmware updates are required; the battery simply slots into the existing compartment.

4.44 Wh capacity restores a full shift of talk time

At 1.2 Ah the cell delivers the same energy as the original, supporting typical daily usage on the compatible Cisco handsets. It will not extend runtime beyond the handset's design limits and is unsuitable for devices that require a higher capacity pack.

Questions about this item

How often will the 1200mAh Li-Polymer battery need replacing?

With daily charge cycles, the 1.2 Ah Li-Polymer cell typically lasts one to two years before runtime drops below useful levels.

What limits talk time during a long shift with the 3.7V pack?

The 4.44 Wh capacity sets the hard ceiling; continuous voice use drains the 1200mAh cell in a few hours.

Does the 83.90 x 52.70 x 7.80 mm pack get hot or noisy on all-day standby?

Li-Polymer chemistry runs silent and stays near ambient temperature during normal standby on the Cisco CP-7921G.
