The BIS VISTA is a portable neurological monitor used in clinical settings to track brain electrical activity and sedation depth during anesthesia and critical care. Voltage and capacity match OEM specifications.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBIS VISTA 185-0152 and 186-0208 compatibility:\u003c\/strong\u003e\n    Both monitor variants share the same 7.4V battery bay, connector pinout, and BMS communication protocol. A single cell services both units 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 a full charge and discharge on a BIS VISTA unit. The BMS accepted the cell on first insertion, completed the power-on self-test, and held voltage within the expected range under continuous display and sensor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, allow the monitor to complete its full startup self-test cycle without interruption. Medical-grade BMS firmware runs a battery verification pass at boot. Cutting power during this 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\"\u003eBIS VISTA not completing boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIS VISTA runs a BMS handshake during startup that checks cell voltage against a minimum threshold before allowing full boot. A new cell that has been in storage can sit below this threshold even if it shows a partial charge state. The monitor interprets this as a degraded or incompatible cell and halts the boot sequence. Connect the monitor to AC power and run a full charge cycle before attempting battery-only operation — this brings the cell into the accepted voltage window and allows boot to complete normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the BIS VISTA charge controller applies a conservative current limit to an unrecognised cell. This causes the charge cycle to terminate early, and the indicator may plateau at 85–95% rather than reaching full. This is a charge IC behaviour, not a cell fault. Run a full discharge to the low-battery alarm threshold, then recharge completely — after one full cycle the charge IC recalibrates its termination point and the indicator will reach 100%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381481668698,"sku":"BWCS-AMS456MD-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381481701466,"sku":"BWCS-AMS456MD-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381481734234,"sku":"BWCS-AMS456MD-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMS456MD-1.webp?v=1778901170","url":"https:\/\/batteryweb.com\/products\/medtronic-nellcor-covidien-bis-vista-monitor-185-0152-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
