It restores power to a handset that no longer holds charge or shuts off unexpectedly during calls. No OEM part number is published for this cell, but the dimensions — 53.40 × 34.22 × 5.40mm — match the ICW-1000B battery bay directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eICW-1000B handset fit:\u003c\/strong\u003e\n    The ICW-1000B uses a slim single-cell Li-ion pack at 3.7V nominal. The connector orientation and cell footprint are specific to this handset — the base station charges via contact pins that expect this exact voltage range to trigger the charging circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the bench, monitoring BMS cutoff at both ends. The protection circuit tripped correctly at high-voltage cutoff and low-voltage lockout, keeping the cell within safe operating limits across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Li-ion cordless handsets:\u003c\/strong\u003e\n    After installing this battery, seat the handset in the base and leave it for a full charge cycle before making any calls. Li-ion cells shipped in storage-state charge need one complete charge before the BMS registers accurate capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ICW-1000B base station shows no charge indicator on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells in storage are typically held at around 3.6–3.7V to reduce degradation during shipping. Some cordless base stations expect the handset battery to be below a threshold voltage before triggering the charge circuit — if the cell arrives at or above that threshold, the base reads it as already charged and shows no activity. This is not a fault. Seat the handset, wait ten minutes, then remove and reseat it. The base should pick up the charge cycle once the BMS communicates cell state correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not pairing with base after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving a depleted Li-ion pack cuts all power to the ICW-1000B handset, which clears the DECT pairing stored in volatile memory on some units. The handset comes back up with no registered base, so it won't ring or transmit. Re-register the handset using the base station's paging or registration button — typically hold it for five seconds until the base confirms the link. Once paired, fully charge the handset before testing call quality.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339887018074,"sku":"BWCS-UDT100SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339887050842,"sku":"BWCS-UDT100SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339887083610,"sku":"BWCS-UDT100SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UDT100SL-1.webp?v=1778366945","url":"https:\/\/batteryweb.com\/products\/incom-icw-1000b-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
