It replaces OEM part numbers 110273 and 88888813. These monitors are clinical-grade devices used for non-invasive SpO2 and pulse rate monitoring in hospital and portable care settings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN5500 and N5600 compatibility:\u003c\/strong\u003e\n    Both monitors share the same 14.4V battery platform, connector pinout, and BMS handshake protocol. A single cell format covers both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the N5500 charge and discharge sequence. The BMS accepted the cell, completed charge termination correctly, and held voltage within spec under the monitor's continuous SpO2 load profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the N5500 or N5600 to complete its full power-on self-test without interruption. These monitors run a BMS verification routine at startup — cutting power mid-sequence logs a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe N5500 runs a startup self-test that includes a battery verification step. If the cell voltage is below the monitor's minimum boot threshold — typically around 12.0V — the device will stall or abort the boot sequence entirely. This can happen with a new Ni-MH cell that has self-discharged in storage. Charge the battery fully before the first installation, then power on and let the self-test run to completion without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe N5500's BMS uses a capacity threshold calibrated to OEM cell characteristics. A new replacement cell may not satisfy that threshold on the first cycle because the BMS has no discharge history to reference. The monitor flags this as a low battery condition even though the cell is fully charged. Run one complete charge-to-discharge-to-charge cycle on the device before clinical use — this gives the BMS enough data to update its internal capacity estimate and clear the alarm.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381459910746,"sku":"BWCS-NPT560MD-1","price":113.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381459943514,"sku":"BWCS-NPT560MD-2","price":130.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381459976282,"sku":"BWCS-NPT560MD-3","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NPT560MD-1.webp?v=1778900984","url":"https:\/\/batteryweb.com\/products\/nellcor-n5500-monitor-replacement-battery-144v-3800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
