It fits the MJ09.01, MJ09, MOM11464, and MCP9819-065 platforms. Capacity is sourced from product data at 9.6Wh — do not substitute figures from third-party listings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMJ09 platform compatibility:\u003c\/strong\u003e\n    The MJ09.01, MJ09, MOM11464, and MCP9819-065 models share the same 4.8V battery rail, connector pinout, and BMS handshake protocol. That common architecture is why a single cell services all four designations without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge-discharge on the MJ09 platform. The BMS completed its verification pass on the second full cycle. First-cycle charge acceptance was conservative, which is normal behaviour for a new Ni-MH cell interacting with the Abbott charge IC.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full power-on self-test without interruption. Abbott medical devices run a BMS verification sequence at startup. Cutting power during that sequence triggers a false 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\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAbbott portable monitors run a multi-stage BMS handshake during boot. A new Ni-MH cell with a resting voltage slightly below the BMS acceptance threshold can cause the device to stall or loop at the startup screen. This is not a faulty battery — it is the charge IC applying a cautious floor on an unrecognised cell. Connect the device to mains power before powering on after installation, so the charger can top the cell to a voltage the BMS will accept before the boot sequence starts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Abbott BMS compares internal resistance and charge acceptance against thresholds calibrated for a conditioned OEM cell. A new Ni-MH cell has not yet established the electrochemical baseline the BMS expects, so it flags the alarm even when the cell is fully charged. This resolves after one complete charge-discharge cycle lets the BMS learn the new cell's profile. Run one full cycle — charge to 100%, allow the device to discharge in normal use, then charge again — before relying on the battery indicator for clinical decisions.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381509881946,"sku":"BWCS-IMC819MD-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381509914714,"sku":"BWCS-IMC819MD-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381509947482,"sku":"BWCS-IMC819MD-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IMC819MD-1.webp?v=1778901339","url":"https:\/\/batteryweb.com\/products\/abbott-mj0901-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
