Cisco Rechargeable Battery for Wireless IP Phone 8821

The Cisco CP-BATT-8821= is a rechargeable Lithium-ion battery created exclusively for the Cisco 8821 Wireless IP Phone, giving the handset a dependable source of power for long shifts and busy facilities.

With a capacity of 2060 mAh at 4.35 volts, the battery supports up to 13 hours of talk time and about 240 hours of standby. When it is time to recharge, it adapts to the schedule at hand. A Cisco power adapter, desktop charger, or multicharger brings it to full capacity in roughly three hours, while a standard USB connection completes the charge in about six hours. This flexibility makes it easy to top up power during a short break or overnight without special procedures.

Keeping a spare CP-BATT-8821= on hand is a practical way to eliminate downtime. Nurses moving between patient rooms, retail associates on the sales floor, and warehouse teams spread across large facilities can swap batteries in seconds instead of waiting by an outlet, helping them stay reachable and productive. IT departments also benefit from the quick-swap design, as it reduces device rotation and keeps the wireless phone fleet ready for the next shift.
