It matches the OEM voltage and chemistry the pump's BMS expects. Use the product data capacity figure — 4400mAh — as the reference spec for this listing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e8000 series platform fit:\u003c\/strong\u003e\n    The 8000, 8015, 8220, and 8001 share the same 12V battery bay, connector pinout, and BMS handshake protocol. A single cell design services the entire platform 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 and discharge on the 8000 platform and confirmed the BMS completed its verification routine without triggering a fault. Charge acceptance was consistent with OEM cell behaviour across all test runs.\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 pump to complete its full power-on self-test without interruption. The 8000 series BMS runs a cell verification sequence at startup — cutting power mid-sequence causes a false battery fault flag that persists until the next complete reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSelf-test failure after battery swap on the 8000 series\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Alaris 8000 BMS stores chemistry and charge-state data from the previous cell. When a new Ni-MH cell is installed, the BMS compares the new cell's internal resistance and charge profile against stored values from the old cell. If the new cell has not completed at least one full charge-discharge cycle, internal resistance reads high and the self-test throws a fault. Run one full charge cycle on the pump before placing the unit back into clinical rotation. This resets the BMS learn cycle and allows the pump to accept the new cell as valid.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first charge, the 8000 series charge IC applies a conservative current limit to an uncharacterised cell — this is by design, not a fault. The indicator may plateau at 85–95% and stop climbing. The cell is not full at that point; the charge IC has simply hit its cautious upper threshold before the cell profile is established. Fit the battery, run the pump through a full discharge to the low-battery alarm threshold, then recharge completely. After that first full cycle, the charge IC maps the cell accurately and the indicator reaches 100%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381504245850,"sku":"BWCS-AMS812MD-1","price":118.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381504278618,"sku":"BWCS-AMS812MD-2","price":139.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381504311386,"sku":"BWCS-AMS812MD-3","price":155.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMS812MD-1.webp?v=1778901324","url":"https:\/\/batteryweb.com\/products\/alaris-medicalsystems-8000-replacement-battery-12v-4400mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
