It replaces OEM part number E-0143 and fits the Medic 4 directly. Capacity is rated at 60Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMedic 4 platform fit:\u003c\/strong\u003e\n    The Medic 4 uses a 24V Ni-MH pack with a specific connector and BMS handshake that authenticates cell chemistry on boot. This replacement matches that voltage rail and pack geometry so the device completes its startup sequence without throwing a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Medic 4's charge and discharge profile. The BMS accepted the cell chemistry on the first charge cycle and passed the device's internal self-test without intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the Medic 4 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window logs a battery fault that persists 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\"\u003eMedic 4 not completing boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Medic 4's BMS runs a cell verification step during startup. On a new Ni-MH pack that hasn't completed its first full charge-discharge cycle, the BMS can flag a chemistry mismatch and halt the boot sequence. This is a calibration state, not a hardware fault. Run one full charge cycle before attempting clinical deployment — the BMS learn cycle completes during that first discharge and the boot sequence clears on the next startup.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMedic 4 alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Medic 4 measures battery state against a voltage threshold calibrated to an aged OEM cell's discharge curve. A fresh Ni-MH pack delivers a slightly different voltage profile in its first few cycles, which can trigger the low-battery alarm even when the pack is fully charged. This is not a defective cell — it is the BMS reading a new cell's curve as out of range. Complete one full charge-discharge cycle and the alarm clears. If the alarm persists after three cycles, check resting voltage at the pack terminals — it should read at or above 24V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381456732250,"sku":"BWCS-BRM400MD-1","price":187.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381456765018,"sku":"BWCS-BRM400MD-2","price":219.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381456797786,"sku":"BWCS-BRM400MD-3","price":243.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BRM400MD-1.webp?v=1778900983","url":"https:\/\/batteryweb.com\/products\/burdick-medic-4-defibrillator-replacement-battery-24v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
