It fits the cordless satellite mic unit used with Cisco conference phone systems. Swap it when the original battery no longer holds a charge or fails to power the unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCP-8832 Wireless Expansion Microphone fit:\u003c\/strong\u003e\n    The CP-8832 wireless mic draws from a single-cell 3.7V Li-Polymer pack to run both the audio pickup circuit and the 2.4GHz wireless link simultaneously. This replacement matches that cell configuration, voltage rail, and connector orientation so the dock-side charging circuit and BMS handshake function without reconfiguration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the CP-8832 platform, confirming the BMS accepted the cell, the dock registered a valid charge state, and protection circuits tripped correctly at low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-session calibration after swap:\u003c\/strong\u003e\n    After installing, run one complete charge cycle before your first meeting. The CP-8832 maps battery state against voltage thresholds during normal operation — a fresh pack that hasn't been cycled yet will cause the indicator to read inaccurately for the first session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage sag under combined audio and wireless draw in the CP-8832\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CP-8832 wireless mic runs audio pickup and a 2.4GHz radio link off the same 580mAh cell. When both circuits draw simultaneously during an active call, instantaneous current demand spikes. A degraded original battery drops voltage sharply under that combined load, which the BMS interprets as a low-cell event and cuts output. A new cell with full capacity handles the combined draw without triggering that cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharging dock not registering the new battery after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the dock shows no charging activity after you seat the mic, the most common cause is contact resistance between the pack terminals and the dock's charging pins. Li-Polymer packs shipped in storage mode can also have a surface oxide layer on the contacts. Wipe the pack contacts with a dry cloth, reseat the mic firmly in the dock, and confirm the dock LED changes state. If the pack voltage reads below 3.0V on a multimeter, it may be in deep-discharge lockout — leave it on dock for 15–20 minutes to allow the recovery charge circuit to bring it above the BMS re-initialisation threshold of approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339864080474,"sku":"BWCS-CIP832SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339864113242,"sku":"BWCS-CIP832SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339864146010,"sku":"BWCS-CIP832SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CIP832SL-1.webp?v=1778366843","url":"https:\/\/batteryweb.com\/products\/cisco-cp-8832-wireless-expansion-microphone-replacement-battery-37v-580mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
