It replaces OEM part numbers 195-0019, BATT110290, AS30077, OM11230, CSC07129, and B11230. These monitors are used for BIS-based patient monitoring during anesthesia and recovery, where consistent power delivery matters.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA2000 and BIS View platform fit:\u003c\/strong\u003e\n    The A2000, A2000 BIS Monitoring, and BIS View Monitoring units share the same battery bay dimensions, connector pinout, and 7.2V voltage rail. One cell works across all three configurations without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on the A2000 platform. The onboard BMS flagged a conservative charge limit on the first cycle, which cleared after one full charge-discharge pass. Capacity registered at rated spec from cycle two onward.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap power-on self-test:\u003c\/strong\u003e\n    After installing this battery, let the A2000 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup. Cutting power during this window registers a battery fault that sticks until the next clean reboot — not a cell defect.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eA2000 alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe A2000 charge IC compares incoming cell data against thresholds calibrated to the OEM cell's internal resistance profile. A new replacement cell reads slightly differently on the first cycle, so the BMS may flag a low-battery alarm even when the cell is fully charged. This is a calibration mismatch, not a fault with the cell. Run one complete charge-discharge cycle and let the device finish its self-test — the BMS updates its reference values and the alarm clears. After that cycle, the battery registers correctly at full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–3% per day. A cell stored for several months can drop below the A2000's BMS recovery threshold — typically around 5.4V for a 7.2V pack — and the device will not boot. Place the battery on a compatible external Ni-MH charger first to bring voltage above the recovery floor. Once the cell reads above approximately 6.0V, reinstall it and the A2000's internal charger will take over and complete the charge normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381422293082,"sku":"BWCS-AMS200MD-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381422325850,"sku":"BWCS-AMS200MD-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381422358618,"sku":"BWCS-AMS200MD-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMS200MD-1.webp?v=1778900661","url":"https:\/\/batteryweb.com\/products\/aspect-medical-system-monitor-a2000-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
