It replaces the primary cell that powers the device through its self-test cycles and defibrillation therapy delivery. Li-MnO2 chemistry is the correct type for this AED — substituting a different chemistry will cause self-test failures and BMS rejection.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMRL Jumpstart AED compatibility:\u003c\/strong\u003e\n    The Jumpstart AED runs a dedicated BMS that verifies cell chemistry and internal resistance at every power-on. Li-MnO2 cells hold a flat discharge curve under the high-current pulse loads the AED demands — other chemistries sag below the BMS threshold and trigger a fault before therapy is ever delivered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Jumpstart's full self-test sequence and confirmed the BMS accepted it without faults. Charge acceptance was normal and the cell held voltage through simulated high-current pulse draws without triggering low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test procedure:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without interruption or button presses. The Jumpstart's BMS runs a chemistry verification at startup — interrupting this sequence locks in a false battery fault that won't clear 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\"\u003eWhy the Jumpstart AED rejects a new battery on first boot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Jumpstart's BMS applies a strict internal resistance threshold during its startup verification. A fresh Li-MnO2 cell that has been in storage often reads slightly elevated resistance until the chemistry stabilises through one full charge-discharge cycle. The BMS reads this as an out-of-spec cell and throws a battery fault. Running one complete charge cycle before placing the device back into service clears this condition and allows the BMS to accept the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the Jumpstart's charge IC applies a conservative current limit to a new cell — the indicator may plateau at 90–95% for an extended period before completing. This is the charge controller protecting the fresh cell, not a fault with the battery or the charger. Do not remove the battery or interrupt charging during this phase. Let the charge cycle complete fully; the cell will reach full capacity and the indicator will clear to 100%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381490155610,"sku":"BWCS-WB113MD-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381490188378,"sku":"BWCS-WB113MD-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381490221146,"sku":"BWCS-WB113MD-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WB113MD_1.webp?v=1778901266","url":"https:\/\/batteryweb.com\/products\/mrl-jumpstart-aed-replacement-battery-12v-3000mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
