It replaces OEM part B11491 directly. The S\/5 Light Monitor is a portable vital signs monitor used in hospital and clinical environments where backup power is critical during patient transport or power interruptions.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS\/5 Light Monitor N-LBB platform:\u003c\/strong\u003e\n    The N-LBB designation indicates the battery-backed configuration of the S\/5 Light Monitor. These units share a specific 13.2V rail and a BMS handshake that authenticates cell chemistry on startup — Ni-MH cells must match the charge termination profile the device expects, or the monitor will flag a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge-discharge cycles on this cell and confirmed the BMS accepted the battery without fault codes. Charge termination triggered correctly at full capacity, and the protection circuit held stable under the S\/5's continuous monitoring load profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the S\/5 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at boot — cutting power during this cycle causes 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\"\u003eS\/5 Light Monitor alarming low battery with a freshly charged replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S\/5's charge IC applies a conservative capacity threshold during early cycles on a new Ni-MH cell. On the first few charges, the BMS may not recognise the cell as fully conditioned, triggering a low battery alarm even when the cell is at or near full charge. This is not a fault with the replacement battery — it reflects how the device calibrates to new cells. Run one complete charge-discharge cycle through the monitor before clinical use to allow the BMS to update its capacity baseline.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eS\/5 Light Monitor will not power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and if the cell voltage drops below the S\/5's BMS recovery threshold, the monitor will not power on even when connected to mains. The BMS interprets an excessively depleted cell as a fault condition and blocks startup. Connect the monitor to AC power first and leave it for a minimum of 30 minutes before attempting to boot — this allows the charge IC to bring the cell above the recovery threshold, typically around 10.5V, before the BMS re-initialises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381508571226,"sku":"BWCS-DES500MD-1","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381508603994,"sku":"BWCS-DES500MD-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381508636762,"sku":"BWCS-DES500MD-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DES500MD-1.webp?v=1778901305","url":"https:\/\/batteryweb.com\/products\/datex-ohmeda-s5-light-monitor-n-lbb-replacement-battery-132v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
