It replaces OEM part numbers LM345001A, 115-026737-00, and 022-000124-00. Li-MnO2 chemistry is standard for AED applications — it holds a stable open-circuit voltage over long standby periods and delivers the high-current pulse the defibrillator needs during a shock event.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBeneHeart D1 compatibility:\u003c\/strong\u003e\n    The D1 defibrillator uses a BMS handshake that verifies cell chemistry and voltage at power-on. This battery meets the 12V nominal rail requirement and passes the D1's internal self-test sequence on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the battery through the D1's full power-on self-test cycle. The BMS verified charge state, cleared no fault codes, and the charge indicator progressed normally through all status stages.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the D1 complete its full power-on self-test without interrupting it. Pressing buttons or cycling power mid-sequence causes the BMS to log 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\"\u003eWhy the BeneHeart D1 self-test fails after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe D1 runs a BMS learn cycle on first use with a new cell. During this cycle, the device checks that the battery voltage holds above the OEM-programmed threshold under a brief internal load. A new Li-MnO2 cell that has not completed one full charge-discharge cycle may read slightly below the expected threshold, triggering a self-test failure code. This is not a faulty battery — it is the BMS applying conservative limits against an uncharacterised cell. Run one complete charge cycle, then repeat the self-test before clinical deployment.\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 a fresh Li-MnO2 cell, the D1's charge IC applies a reduced top-off current until the internal impedance profile is established. This causes the charge indicator to plateau at 90–95% and sit there longer than expected. The cell is not defective — the charge IC is running a conservative finishing algorithm on an uncharacterised pack. Allow the charge cycle to complete fully without removing the battery. After the first full cycle, subsequent charges reach 100% at normal speed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381470920794,"sku":"BWCS-MBD100MD-1","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381470953562,"sku":"BWCS-MBD100MD-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381470986330,"sku":"BWCS-MBD100MD-3","price":141.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MBD100MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/mindray-beneheart-d1-replacement-battery-12v-4200mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
