Replacement battery for Polycom conference phones

This Cameron Sino battery replaces the original power pack in Polycom SoundStation 2W, SoundStation 2W EX and SoundStation2 Wireless Conference speakers. It matches the factory voltage of 7.4 volts and capacity of 4400 milliamp_hours. The pack uses a fully decoded chip so the handset recognises it immediately. Installers can follow widely available online videos for a straightforward swap.

Thermals noise and power in normal use

The lithium-ion cell delivers 32.56 watt-hours at the rated 7.4 volts, drawing only the current the speaker requires during calls. No active cooling is involved, so operation is silent. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits, keeping temperatures stable throughout a typical meeting day. The pack weighs 180.6 grams and measures 130.82 by 36.79 by 18.48 millimetres.

Deciding specification: 4400mAh capacity at 7.4V

Capacity and voltage together define whether this pack will power your specific SoundStation model for the expected talk time. If your device requires a different voltage or a higher milliamp-hour rating, this unit will not meet the need. Buyers who need longer runtime between charges or a different form factor should look elsewhere. The part numbers 1520-07803-004, 2200-07804-002, CP-2WBATT24 and L04L40627 confirm exact compatibility.

Questions about this item

How do I install the 130.82 x 36.79 x 18.48 mm pack in my SoundStation 2W EX, and which step do people get wrong?

Slide the pack into the base until the latch clicks; the common error is forcing it before the connector aligns, which can bend the pins.

What maintenance or replacement will the 4400mAh 7.4V pack need later?

The built-in protection circuit guards against overcharge and deep discharge, so no routine service is required; replace the pack when talk time drops below your needs.

What limit appears first during a long conference call on this battery?

The 32.56 Wh capacity sets the runtime ceiling; after roughly eight hours of continuous use the voltage falls to the cutoff point and the speakerphone powers down.
