It restores the phone's ability to operate untethered and to maintain backup power during outages. Voltage and physical dimensions match the original: 53.26 x 34.10 x 6.10mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eICW-1000G platform fit:\u003c\/strong\u003e\n    The ICW-1000G uses a single-cell 3.7V Li-ion pack with a specific connector orientation and BMS handshake tied to the phone's charge management circuit. This cell matches that connector and voltage rail so the phone's firmware recognises the battery correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the ICW-1000G charge circuit and confirmed the BMS accepted the pack without fault flags. Charge termination triggered cleanly at 4.2V with no overcharge events observed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use backup activation:\u003c\/strong\u003e\n    After fitting this battery, power cycle the phone and leave it on charge for a full four hours before testing backup function. The ICW-1000G firmware will not route power through the backup circuit until the cell has completed at least one full charge cycle from the mains adapter.\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-1000G drops its settings when mains power cuts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ICW-1000G stores active call settings and network configuration in volatile memory backed by the battery. If the replacement cell ships below 3.5V from storage, the phone's backup circuit sees it as insufficient and bypasses it entirely during a power cut. This means settings revert to defaults even though a battery is physically present. Charge the phone to 4.2V before any outage test — the backup circuit will not activate below that threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone shows low battery warning immediately after new cell is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage and shipping, so the KAL523450AR replacement may arrive at 3.3–3.6V — below the ICW-1000G's low-battery threshold of roughly 3.7V. The phone reads that resting voltage and immediately flags a low-battery warning, even with a brand-new cell installed. This is not a fault with the battery. Place the phone on its charger and allow a full charge cycle; the warning will clear once the cell reaches 3.9V or above.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428090609754,"sku":"BWCS-UDG100SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428090642522,"sku":"BWCS-UDG100SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428090675290,"sku":"BWCS-UDG100SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UDG100SL-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/incom-icw-1000g-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
