It fits the Pousse Seringue Perfusor FM Seringue D variant under the same part reference. This pump is a clinical infusion device used in hospital settings to deliver IV medication at controlled rates.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePerfusor FM platform fit:\u003c\/strong\u003e\n    The Perfusor FM Seringue D runs a 7.2V motor rail with a BMS that validates cell chemistry at startup. This cell matches the voltage profile and connector orientation the device expects during its power-on handshake.\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 under a simulated syringe pump load. The BMS accepted the cell, completed its self-test sequence, and held voltage within the expected window across the draw profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle protocol on medical devices:\u003c\/strong\u003e\n    After installing this battery, allow the Perfusor FM to complete its full power-on self-test without interruption. The BMS runs a verification routine at boot — cutting power mid-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\"\u003eLow battery alarm on the Perfusor FM immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Perfusor FM's charge IC applies a conservative acceptance threshold calibrated to aged OEM cells. A new Ni-MH cell has a slightly different internal resistance profile during its first few cycles, which the BMS may read as below threshold even when the cell is fully charged. This is not a fault with the cell — it resolves after one complete charge-discharge cycle. Run the battery through a full cycle before drawing any clinical conclusions about charge state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePerfusor FM will not power on after the replacement battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and if voltage drops below roughly 5.4V the BMS enters a protection state and refuses to initiate a normal boot. The pump will show no response or a blank screen. Place the battery on charge for a minimum of 30 minutes before attempting to power on — this brings the cell above the BMS recovery threshold. If the device still does not boot after a full charge, check that the battery contacts are seated and clean.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381403025498,"sku":"BWCS-BRA311MD-1","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381403058266,"sku":"BWCS-BRA311MD-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381403091034,"sku":"BWCS-BRA311MD-3","price":113.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BRA311MD-1.webp?v=1778900535","url":"https:\/\/batteryweb.com\/products\/bbraun-syringe-pump-perfusor-fm-seringue-d-replacement-battery-72v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
