It replaces OEM part numbers 97195 and 97196. Li-MnO2 chemistry is specified for this device class because it holds a stable voltage curve under the high-current pulse loads that defibrillation discharge requires.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAED-M, Defimon XD3, Heartsave 6 and 6S compatibility:\u003c\/strong\u003e\n    These models share the same 15.5V power rail, physical form factor, and BMS handshake protocol, which is why a single cell pack services all of them. The connector pinout and BMS communication line are identical across the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge-discharge cycles on a Primedic-compatible test rig and confirmed the BMS completed its calibration sequence without triggering a fault code. Charge acceptance and termination voltage matched OEM specification at 15.5V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the device to complete its full power-on self-test without interruption. AED-M units run a BMS verification routine at startup — cutting power during this sequence logs 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\"\u003eSelf-test failure after battery swap on the AED-M\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AED-M BMS compares the new cell's internal resistance and voltage signature against stored OEM thresholds at every startup. A fresh Li-MnO2 cell that has not yet completed a full charge-discharge cycle will often sit just outside those thresholds, triggering a self-test fault even though the pack is functional. This is a calibration gap, not a hardware fault. Run one complete charge-discharge cycle through the device before placing it back in service — after that cycle, the BMS updates its reference values and self-test passes cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm persisting immediately after confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS charge IC applies a conservative upper voltage limit on a new cell during its first charge, resulting in a terminal voltage slightly below the threshold the alarm logic uses to clear the low-battery flag. The pack is not defective — it has not yet been allowed to reach full OEM charge termination voltage. Charge the unit a second time from a fully seated, confirmed connection and let the charge run to completion without interruption. After this second cycle, terminal voltage typically reaches 15.5V and the alarm clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381395161178,"sku":"BWCS-PRH600MD-1","price":362.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381395193946,"sku":"BWCS-PRH600MD-2","price":432.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381395226714,"sku":"BWCS-PRH600MD-3","price":485.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRH600MD-1.webp?v=1778900564","url":"https:\/\/batteryweb.com\/products\/primedic-aed-m-replacement-battery-155v-7200mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
