It fits units listed under part numbers 2056410-001, 2056410-002, 2066261-013, 2066261-085, and M2834. Capacity is rated at 37.44Wh — matching the original cell's voltage rail and connector spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMAC 2000 platform compatibility:\u003c\/strong\u003e\n    The MAC 2000, MAC 2000 EKG, and EKG recorder Mac 2000 all share the same 14.4V battery bay, BMS handshake protocol, and connector pinout — one cell fits the entire line without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the MAC 2000 platform. The BMS completed its charge-acceptance handshake cleanly and held voltage within spec across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installation, allow the MAC 2000 to complete its power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this cycle stores a false battery fault that persists until the next full reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MAC 2000 runs a startup BMS check that compares the cell's reported state-of-charge against an internal threshold before completing the boot sequence. A new cell that sat in storage may report a partial charge, causing the device to stall mid-boot. Connect the MAC 2000 to mains power and allow it to charge the replacement cell fully before attempting a standalone boot. Once the cell reaches 14.4V at the terminals, the boot sequence completes without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the MAC 2000's charge IC applies a conservative capacity threshold calibrated to a broken-in OEM cell. A new replacement cell has not yet completed a learn cycle, so the BMS under-reports available charge and trips the low-battery alarm prematurely. Run one complete charge-to-discharge-to-charge cycle before clinical use. After that first full cycle, the BMS recalibrates its capacity estimate and the alarm clears at the correct threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381453652058,"sku":"BWCS-GMC200MD-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381453684826,"sku":"BWCS-GMC200MD-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381453717594,"sku":"BWCS-GMC200MD-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMC200MD-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/ge-mac-2000-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
