OEM part numbers covered include 10930, 6029, B11229, and HV-9250-003. The Harvard Syringe Pump is a clinical infusion device used in hospital and healthcare settings to deliver precise intravenous medication doses.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHarvard Syringe Pump platform fit:\u003c\/strong\u003e\n    These OEM part numbers share the same 3.6V Ni-CD cell configuration, connector type, and BMS handshake protocol. Any of the four cross-reference numbers will match this pack without wiring modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and load discharge on the Harvard Syringe Pump platform. The BMS accepted the new pack and passed internal resistance verification without flagging a chemistry mismatch.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test requirement:\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 routine at startup — cutting power mid-sequence stores a false battery fault that will persist 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 triggering immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-CD cells from storage have not yet completed a full charge-discharge learn cycle, so the pump's BMS applies a conservative internal resistance threshold that a new cell rarely meets on first charge. The device reads this as a below-minimum state and triggers the alarm even though the cell is fully charged. Run one complete charge-to-cutoff, then a full discharge under device load, and the BMS recalibrates its threshold. After that cycle, the alarm clears and the pump reports charge state accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHarvard Syringe Pump failing to boot after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-CD cells self-discharge at roughly 15–20% per month in storage. If a replacement pack has been sitting long enough, the cell voltage drops below the BMS recovery threshold — typically around 3.0V — and the pump will not initiate its boot sequence. Connect the battery to the charger before installing it in the device and allow a full charge cycle to complete. Once the cell climbs above the recovery threshold, the pump will boot and run its self-test normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381364228186,"sku":"BWCS-BRM925MD-1","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381364260954,"sku":"BWCS-BRM925MD-2","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381364293722,"sku":"BWCS-BRM925MD-3","price":75.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BRM925MD-1.webp?v=1778900266","url":"https:\/\/batteryweb.com\/products\/bard-medsystems-harvard-syringe-pump-replacement-battery-36v-5000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
