Compatible Li-Polymer battery for Cisco 8821

This 1.7 Ah replacement battery fits Cisco 8821 wireless IP phones including the CP-8821-K9-BUN and CP-8821-EX-K9-BUN bundles. It matches the original CP-BATT-8821 and 74-102376-01 part numbers for direct OEM compatibility. Office users and field staff who rely on the 8821 handset for daily calls receive a like-for-like power source. The black Li-Polymer cell restores talk and standby time without modification.

Verify handset model and original part number

Confirm the phone is a Cisco 8821 series handset before ordering; the battery is not compatible with other Cisco desk phones or DECT models. Check the label on the existing pack for part numbers 74-102376-01, CP-BATT-8821 or GP-S10-374192-010H to ensure an exact match. The physical footprint measures 101.50 x 41.70 x 4.20 mm so the battery bay must accept those dimensions. Buyers needing a different voltage or capacity should look elsewhere.

Steady output during extended shifts

Rated at 3.8 V and 1700 mAh for 6.46 Wh, the cell delivers consistent voltage across a full work shift rather than only in short bursts. Li-Polymer chemistry maintains stable discharge while the handset cycles between active calls and idle periods. The pack is designed for daily charge cycles in office or mobile environments. Users who need higher capacity for multi-day use without recharging will need a different solution.

Questions about this item

Does the battery arrive ready to fit the Cisco 8821, or do I need extra screws or tools?

The pack ships as a single unit sized 101.50 x 41.70 x 4.20 mm and slots straight into the handset; no additional hardware is required.

I only see one capacity listed — 1.7 Ah at 3.8 V — so how do I know it is the right choice?

That single 1700 mAh / 6.46 Wh Li-Polymer cell is the direct replacement for part numbers 74-102376-01, CP-BATT-8821 and GP-S10-374192-010H, so it matches the original specification exactly.

What does the 1.7 Ah rating actually deliver in daily use on the 8821 handset?

The 3.8 V 1700 mAh cell restores the phone to its factory talk-time and standby figures, giving a full shift of typical office calls before a recharge is needed.
