These are medical-grade clinical devices used in neonatal and pediatric care settings. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN-15, N-10, and AS70 shared platform:\u003c\/strong\u003e\n    All three devices draw from a 12V sealed lead-acid rail with the same physical footprint and connector orientation. The BMS in each unit expects the same internal resistance profile that SLA chemistry provides — swapping to a different chemistry trips a fault condition in the charge controller.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge-discharge sequence and confirmed the BMS accepted state-of-charge handshake without triggering a low-battery alarm. Charge acceptance held steady from 10.5V recovery up through 13.8V float.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation power-on protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the device to complete its full power-on self-test without interruption. The N-15 runs a BMS verification routine at startup — cutting power mid-sequence stores a false battery fault that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the N-15 boot sequence stalls after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe N-15 runs a startup verification loop that checks cell voltage, internal resistance, and BMS handshake before releasing the display for use. A freshly installed SLA cell that hasn't completed its first full charge cycle can present a resistance value outside the expected window, causing the boot sequence to stall or loop. This isn't a faulty battery — it's the charge controller applying conservative limits to an unconditioned cell. Run one complete charge cycle on the device's own charger before clinical use, and the boot sequence will clear normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow-battery alarm triggering on a fully charged new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe N-15's BMS sets its low-battery threshold against the internal resistance and resting voltage profile of a conditioned OEM cell. A new SLA battery that hasn't been through at least one full charge-discharge cycle can read as marginal even when fully charged, triggering the alarm incorrectly. The fix is to complete one full discharge-to-recharge cycle using the device itself — not a bench charger — so the BMS can recalibrate its state-of-charge baseline. After that cycle, the resting voltage should hold above 12.6V and the alarm will not re-trigger during normal use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381385429082,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381385461850,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381385494618,"sku":"BWCS-SHT160MD-3","price":415.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHT160MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/narco-air-shields-warm-weigh-infant-scale-n-15-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
