It matches the original cell chemistry, voltage rail, and connector pinout that the pump's BMS expects during startup verification. Capacity is 22.2Wh as shipped.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVp7 platform compatibility:\u003c\/strong\u003e\n    The Vp7, FBALCO0059, and Kabi VP7 variants share the same 11.1V three-cell architecture and BMS handshake protocol. The LJP654169-3S and KAY0654169-3S part numbers reference the same cell configuration — 3ICP7\/41\/69 — so all listed models accept this pack without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the Vp7 platform. The BMS completed cell authentication on the first boot, passed voltage threshold checks across all three cells, and held the charge indicator correctly through a full drain cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the pump complete its full power-on self-test without interruption. The Vp7 runs a BMS verification sequence at each startup. Cutting power during that sequence causes a latched battery fault that does not clear until the device completes a clean reboot from a fully charged state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Vp7 flags a battery fault on the first boot after a swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Vp7 BMS stores a charge profile for the installed cell group. When a new pack goes in, the controller runs a chemistry verification pass before accepting the battery as serviceable. On the first boot, the BMS applies a conservative voltage threshold — tuned for a seasoned OEM cell — and a fresh replacement may sit just below that window. One complete charge-discharge cycle recalibrates the threshold to the new cell's actual resting voltage, and the fault clears without any manual reset.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePump will not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and the Vp7 BMS enforces a minimum recovery voltage — typically around 9V across the three-cell pack. If the cell drops below that floor, the BMS enters a protection state and blocks startup entirely. Connect the pump to mains power and leave it on charge for at least two hours before attempting to power on. Once the pack recovers above the BMS recovery threshold, the device boots normally and resumes charging from there.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381465808986,"sku":"BWCS-FRP700MD-1","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381465841754,"sku":"BWCS-FRP700MD-2","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381465874522,"sku":"BWCS-FRP700MD-3","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FRP700MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/fresenius-vp7-replacement-battery-111v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
