The iCube 1 is a wireless programming device used by audiologists and hearing aid wearers to adjust hearing aid settings over a short-range radio link. When the original cell degrades and can no longer sustain a session, this replacement restores full function.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiCube 1 programmer fit:\u003c\/strong\u003e\n    The iCube 1 runs a combined load — wireless radio transmission and onboard firmware — from a single compact cell. The 453329 cell matches the voltage rail and connector spec the programmer's BMS expects, so the device registers a valid pack on power-up without throwing a charge fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the bench. The BMS accepted the pack, completed a full charge cycle without error, and held voltage within the expected 3.7V nominal range under combined radio and logic draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-session conditioning on the iCube 1:\u003c\/strong\u003e\n    Charge the iCube 1 fully via its dock before running your first programming session. The device's charge controller needs one complete cycle to calibrate the state-of-charge display against the new cell — sessions run before that cycle may show an inaccurate battery indicator.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the iCube 1 drops its wireless link mid-programming session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe iCube 1 transmits to hearing aids over a short-range radio protocol while simultaneously running its onboard logic. That combined draw spikes current demand in short bursts. A degraded or deeply discharged cell sags below the BMS cutoff voltage during these spikes, and the programmer drops the wireless link before the session completes. A fresh cell at full charge sustains voltage through those bursts and keeps the link stable for the duration of a session.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eiCube 1 shows full charge on the dock but cuts off seconds after undocking\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the replacement cell arrives at storage voltage — typically around 3.6V — and the dock registers it as charged without pushing a full cycle. The BMS then cuts the device off almost immediately once real load is applied. The fix is to leave the iCube 1 seated in the dock for a complete charge cycle, confirmed by the charge indicator returning to full from a charge state, before using the device. After that first full cycle the cell will deliver its rated 250mAh under normal load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428103356506,"sku":"BWCS-PNC100SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428103389274,"sku":"BWCS-PNC100SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428103422042,"sku":"BWCS-PNC100SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PNC100SL-1.webp?v=1779934117","url":"https:\/\/batteryweb.com\/products\/phonak-icube-1-wireless-hearing-aid-programmer-replacement-battery-37v-250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
