It matches OEM part number 110976. The Rescue Life is a clinical-grade AED used in emergency cardiac resuscitation, so battery condition is critical to device readiness.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRescue Life and Rescue Life 38 compatibility:\u003c\/strong\u003e\n    Both models run on the same 14.4V Ni-MH power rail with an identical connector and BMS handshake protocol. One battery cell fits both. No adapter, no modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Rescue Life's full charge cycle and confirmed the BMS accepted the pack, completed charge termination correctly, and reported ready status. Capacity held at rated 3800mAh across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the Rescue Life complete its full power-on self-test without interruption. The device's BMS runs a chemistry verification sequence at startup. Cutting power during this sequence logs a false battery fault that persists until the next cold reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Rescue Life's BMS flags a new battery as low on first power-on\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Rescue Life BMS measures internal resistance and open-circuit voltage at startup and compares both against learned thresholds built from the previous cell's data. A fresh Ni-MH pack has slightly higher internal resistance before the first few charge-discharge cycles condition the cell. This mismatch can trigger a low-battery warning even on a fully charged new pack. One complete charge-discharge cycle after installation allows the BMS to recalibrate and clear the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRescue Life fails to complete boot sequence after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day under ambient storage conditions. A pack stored for several months can drop below 10V — the threshold below which the Rescue Life's BMS will not initiate boot. Placing the battery on charge first without fitting it to the device brings voltage back above the 12V recovery floor. Once the charger confirms voltage is above 12V, fit the pack and power on normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381366128730,"sku":"BWCS-PRS380MD-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381366161498,"sku":"BWCS-PRS380MD-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381366194266,"sku":"BWCS-PRS380MD-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRS380MD-1.webp?v=1778900303","url":"https:\/\/batteryweb.com\/products\/progetti-defibrillator-rescue-life-replacement-battery-144v-3800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
