It replaces OEM part number 120049 and restores internal power to the pump's delivery and alarm systems. Capacity is 2000mAh (19.2Wh), matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS2 and P2 platform compatibility:\u003c\/strong\u003e\n    Both the Syringe Pump S2 and P2 share the same 9.6V battery bay, connector pinout, and BMS handshake protocol. One cell format serves both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran a full charge-discharge cycle on the bench. The BMS accepted the cell, completed its initialisation sequence, and the protection circuit held voltage within the expected window under a simulated load profile consistent with syringe pump operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, allow the pump to complete its full power-on self-test without interruption. The device runs a BMS verification step at startup — cutting power during this sequence triggers a false battery fault that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Syringe Pump S2 flags a battery fault in the first 10 cycles\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe S2 uses a charge IC that applies conservative thresholds when it encounters a new or unfamiliar cell. Ni-MH cells also have lower initial capacity on the first few cycles before the electrodes fully activate. The BMS compares measured capacity against a stored threshold, and a new cell can fall short until it's been cycled. Running one complete charge-discharge cycle before clinical use allows the BMS to update its learned capacity value and clear the fault flag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePump will not power on after the battery has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–3% per day at room temperature. A battery stored for several months can drop below the BMS recovery threshold — typically around 8.5V for a 9.6V pack — at which point the protection circuit blocks output entirely. Place the battery on charge for a full uninterrupted cycle before attempting to power the device. If the charger does not recognise the cell, confirm input voltage is stable and retry; most charge ICs will initiate a recovery charge at low current once the cell voltage climbs above 8.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381469413466,"sku":"BWCS-ASP880MD-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381469446234,"sku":"BWCS-ASP880MD-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381469479002,"sku":"BWCS-ASP880MD-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ASP880MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/medima-syringe-pump-s2-replacement-battery-96v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
