It fits the ZIK headset directly, using OEM part number PF056001AA. Voltage and capacity match the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZIK platform fit:\u003c\/strong\u003e\n    The ZIK headset runs both active noise cancellation and Bluetooth audio from a single cell. This battery shares the same 3.7V nominal rail, connector pinout, and physical footprint as the original, so the BMS handshake completes without error codes on the companion app.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through combined Bluetooth streaming and ANC load. The BMS held the cutoff voltage correctly and the headset paired without logging a fault on the Parrot app.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle charge protocol for ZIK:\u003c\/strong\u003e\n    Place the ZIK on its charging cradle immediately after fitting this battery and allow a full charge cycle before use. The ZIK app reads state-of-charge from the cell's BMS — a partial first cycle causes the app to display inaccurate battery percentage until the BMS completes its calibration pass.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ZIK cuts out mid-track after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZIK runs ANC and Bluetooth simultaneously, which creates a combined current draw that spikes above the average load. A new cell shipped at storage voltage — typically around 3.6V — sits close to the BMS low-voltage cutoff threshold. Under that combined spike, the BMS trips and the headset powers off. One full charge cycle before first use brings the cell to its working voltage range and clears this behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParrot app showing wrong battery percentage after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZIK app pulls its battery reading from the BMS state-of-charge register, not a raw voltage measurement. A replacement cell starts with an uncalibrated register, so the app displays a stale or inaccurate figure. Run two full charge-to-discharge cycles and the BMS recalibrates its register. After that the app percentage should track accurately from 4.2V full down to the cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428155654234,"sku":"BWCS-PZK001SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428155687002,"sku":"BWCS-PZK001SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428155719770,"sku":"BWCS-PZK001SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PZK001SL_1.webp?v=1779934278","url":"https:\/\/batteryweb.com\/products\/parrot-zik-replacement-battery-37v-700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
