These are external cardiac defibrillators used in emergency intervention — power continuity is not optional. Capacity figure is sourced from product data at 24Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDefiport NB and Defiscope M compatibility:\u003c\/strong\u003e\n    Both units run the same 12V rail and use identical connector geometry and BMS handshake protocol. A single cell format covers both platforms 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 charge, standby, and discharge on the Defiport NB platform. The BMS accepted the cell, completed its verification sequence, and held voltage within spec across all test draws.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the Defiport NB to complete its full power-on self-test without interruption. Cutting power mid-sequence causes the BMS to log a false battery fault that persists until the next full 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 Defiport NB flags a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Defiport NB BMS stores a chemistry profile from the previous cell. A new Ni-CD cell behaves differently in its first few cycles — internal resistance is slightly higher and charge acceptance is conservative. The BMS compares live cell behaviour against its stored baseline and raises a fault if the delta is too wide. Running one complete charge-discharge cycle recalibrates the BMS to the new cell's actual profile and clears the fault without any manual reset.\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-CD cells self-discharge at roughly 1–2% per day at room temperature. A cell stored for several months can drop below the BMS recovery threshold — typically around 9.6V for a 12V Ni-CD pack — causing the device to refuse to power on entirely. Place the battery on charge for a full uninterrupted cycle before attempting to boot the defibrillator. If voltage has not recovered above 10.5V after a complete charge cycle, the cell has discharged too deeply and requires replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43306856743002,"sku":"BWCS-HBD500MD-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43306856775770,"sku":"BWCS-HBD500MD-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43306856808538,"sku":"BWCS-HBD500MD-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HBD500MD_1.webp?v=1777768812","url":"https:\/\/batteryweb.com\/products\/hellige-defibrillator-defiport-nb-replacement-battery-120v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
