This extended-capacity battery, the Cisco CP-BATT-8821, has been created expressly for the Cisco 8821 wireless IP phone. Offering 4200 mAh, it delivers as much as 13 hours of talk time and 200 hours on standby, so communication stays dependable across the working day. As a lithium-ion cell, it serves as a direct substitute for the standard battery and brings greater longevity in demanding settings.
Built for endurance, the CP-BATT-8821 keeps the same form factor as the original battery, so it fits without issue. Fast charging is supported, and it is optimised for the Cisco 8821 series, covering models CP-8821 and CP-8821-K9. Suited to healthcare, retail and warehouse environments where prolonged use matters.
