It fits the Mac 1600 and ECG Mac 1600 portable cardiac monitors used in hospitals, clinics, and ambulatory care. Cross-references OEM part numbers 2032095-001, 2035701-001, and M2821.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMac 1600 and ECG Mac 1600 compatibility:\u003c\/strong\u003e\n    Both variants run the same 14.8V four-cell architecture with an identical BMS handshake and connector pinout, so one cell covers the full platform. The BMS reads cell chemistry and state-of-charge before the device completes its boot sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on Mac 1600 hardware and confirmed the BMS accepted the new cell, cleared all battery fault flags, 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 installation, let the Mac 1600 complete its full power-on self-test without interruption. The device runs a BMS verification pass at startup — cutting power during this sequence can latch a false battery fault that will not clear until the next complete 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 Mac 1600 flags a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mac 1600's charge IC applies a conservative acceptance threshold when it first sees a new cell — it compares internal resistance and open-circuit voltage against a learned OEM baseline that a fresh replacement has not yet established. If the cell's first-cycle profile falls outside that window, the device logs a fault even though the cell is electrically sound. Running one complete charge-discharge cycle lets the BMS map the new cell's characteristics and clear the mismatch. After that cycle, the fault does not reappear under normal use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMac 1600 will not power on after the battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-ion cells self-discharge at roughly 2–3% per month. If a spare battery has been stored for several months without a top-up charge, its resting voltage can drop below the Mac 1600's BMS recovery threshold — typically around 10V for a 14.8V four-cell pack — and the device will not respond to the power button at all. Place the battery on charge for a minimum of 30 minutes before attempting to power on; most BMS controllers will re-initialise once the pack climbs above that threshold. If the device still shows no response after a full charge attempt, measure pack voltage directly — a reading below 8V indicates the cells have discharged beyond recovery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381399126106,"sku":"BWCS-GMC160MD-1","price":308.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381399158874,"sku":"BWCS-GMC160MD-2","price":368.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381399191642,"sku":"BWCS-GMC160MD-3","price":412.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMC160MD-1.webp?v=1778900536","url":"https:\/\/batteryweb.com\/products\/ge-mac-1600-replacement-battery-148v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
