It fits the RESCUE LIFE 9 defibrillator used in public access and clinical settings. Voltage and capacity match the original cell pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRESCUE LIFE 9 fit:\u003c\/strong\u003e\n    The RESCUE LIFE 9 runs a 14.4V battery bus tied directly to its charge\/shock delivery circuit. Any cell pack on this bus must match that voltage rail exactly — a mismatch causes immediate BMS rejection at startup before the device reaches operational readiness.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the RESCUE LIFE 9 power-on self-test sequence and monitored BMS handshake behaviour. The charge IC applied a conservative current limit on the first charge, which is normal — the cell passed self-test cleanly after one full charge-discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the RESCUE LIFE 9 complete its full power-on self-test without interruption. The device runs BMS verification at startup — cutting power mid-sequence logs a false battery fault that persists until a clean reboot is performed.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRESCUE LIFE 9 not completing boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RESCUE LIFE 9 boot sequence includes a BMS verification step that checks cell voltage against stored OEM thresholds. A new cell fresh from packaging may sit at a resting voltage slightly outside the expected window after transit and storage. The device interprets this as a fault and halts boot. Charge the battery fully before first installation — the cell needs to reach its upper voltage threshold before the BMS will clear the boot check.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRESCUE LIFE 9 alarming low battery immediately after a full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis alarm fires when the BMS self-test threshold — calibrated for the OEM cell's charge profile — does not match the new cell's state-of-charge curve on the first cycle. The device reads a voltage curve it doesn't yet recognise as fully charged. Run one complete charge-discharge cycle on the RESCUE LIFE 9 to let the BMS learn the new cell's profile. After that cycle, charge to full and confirm the low-battery alarm clears at 14.4V resting voltage before returning the device to service.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381408563290,"sku":"BWCS-SND205MD-1","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381408596058,"sku":"BWCS-SND205MD-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381408628826,"sku":"BWCS-SND205MD-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SND205MD-1.webp?v=1778615901","url":"https:\/\/batteryweb.com\/products\/progetti-rescue-life-9-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
