These wireless devices are used in hospitals and care facilities for patient-to-staff communication and emergency call functions. OEM part numbers covered: 401907-105, B10295, and B11050.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eResponder III and BK2000 compatibility:\u003c\/strong\u003e\n    Both platforms share the same 14.4V Ni-MH cell configuration, connector pinout, and BMS handshake protocol — this battery fits either unit without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the BK2000 charge circuit and confirmed the BMS accepted the cell, completed charge termination correctly, and reported accurate state-of-charge after a full conditioning cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without interruption. RAULAND BORG nurse call units run a BMS verification sequence at startup — cutting power during this window logs a false battery fault that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMedical device alarming low battery with a freshly charged replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRAULAND BORG nurse call devices set their low-battery alarm threshold against OEM cell chemistry baselines. A new Ni-MH cell that hasn't completed its first full charge-discharge cycle will read slightly below that threshold at startup, triggering the alarm even when the cell is fully charged. The BMS hasn't yet calibrated its internal capacity estimate against this specific cell. Run one full charge-to-discharge-to-charge cycle before placing the unit in clinical rotation — after that cycle, the alarm will clear and the state-of-charge reading will stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day unprotected. A battery stored for several months can drop below the BMS recovery threshold — typically around 10.0–10.8V for a 14.4V pack — at which point the device won't power on at all. The BMS interprets this voltage as a damaged or absent cell and blocks the power rail as a safety measure. Place the battery on the charger for a full uninterrupted charge cycle; most RAULAND BORG chargers apply a low-current recovery phase that brings the pack back above the BMS floor before switching to normal charge current.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381421080666,"sku":"BWCS-RBK200MD-1","price":84.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381421113434,"sku":"BWCS-RBK200MD-2","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381421146202,"sku":"BWCS-RBK200MD-3","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RBK200MD-1.webp?v=1778900681","url":"https:\/\/batteryweb.com\/products\/rauland-borg-nurse-call-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
