It fits the portable printer unit that outputs results from the i-STAT handheld blood analyzer in point-of-care clinical settings. Voltage and capacity match the original B11464 specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eI-Stat Printer and MCP9819-065 fit:\u003c\/strong\u003e\n    Both models share the same 4.8V Ni-MH cell configuration, connector pinout, and BMS handshake protocol — that is why a single cell pack covers both. Swapping to a different voltage or chemistry will cause the charge IC to reject the pack outright.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge cycle on the I-Stat Printer and confirmed the BMS accepted the cell, completed its verification pass, and reported battery status correctly on the device display. Charge acceptance was clean from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full startup self-test without interrupting power. The I-Stat Printer runs a BMS verification sequence at boot — cutting power mid-sequence stores a false battery fault that persists 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\"\u003eI-Stat Printer not completing boot sequence after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eMedical printers in this class run a startup BMS check that compares cell voltage against a stored threshold before allowing full boot. A freshly installed Ni-MH cell that has partially self-discharged during storage may read below that threshold at power-on. The device interprets this as a fault and stalls the boot sequence rather than proceeding. Charge the replacement pack fully before first installation — Ni-MH cells should sit at approximately 5.4–5.6V measured across the pack terminals before fitting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe I-Stat Printer's charge IC applies a conservative current limit on the first charge cycle when it detects a new or unknown cell. This is not a fault — it is the IC gathering impedance data before it trusts the pack. The indicator will appear to plateau below full for an extended period on that first charge. Run one complete charge-to-discharge-to-charge cycle and the IC recalibrates; the indicator reaches 100% normally from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381509685338,"sku":"BWCS-IMC819MD-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381509718106,"sku":"BWCS-IMC819MD-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381509750874,"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\/martel-i-stat-printer-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
