It matches the OEM voltage rail and cell chemistry used in the original pack. Capacity is rated at 54Wh, identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePortascan \/ Urodyn+ \/ Bardscan platform:\u003c\/strong\u003e\n    All three models share the same 12V Ni-MH battery bay, connector pin-out, and BMS handshake protocol. A single cell pack covers the full platform 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 controlled discharge on a 12V Ni-MH bench fixture. The BMS accepted the cell without triggering a chemistry mismatch fault, and charge termination via delta-V cutoff fired correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test protocol:\u003c\/strong\u003e\n    After installing this pack, let the device complete its full startup self-test sequence without interruption. The Portascan runs a BMS verification routine at boot — cutting power mid-sequence registers a false battery fault 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\"\u003eWhy the Portascan flags a battery fault after a new pack is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Portascan's BMS stores charge history from the previous cell pack. When a new pack is inserted, the controller has no learned capacity baseline for it. Until one full charge-discharge cycle is completed, the BMS applies conservative thresholds that can trigger low-battery or fault warnings even when the cell is fully charged. This is a BMS learn cycle issue, not a cell defect. Run one complete charge-to-full, then a full discharge under normal clinical load, before relying on the battery indicator for clinical decisions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalling below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the Portascan's charge IC applies a conservative current limit to an uncharacterised cell. Delta-V detection — the voltage dip signal that tells the charger the cell is full — is weaker on a new Ni-MH pack than on a conditioned one. The charger may terminate early or display a sub-100% reading as a result. Let the device complete a second full charge cycle; delta-V response normalises as the cell conditions, and the indicator will reach 100% consistently from the third cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381410431066,"sku":"BWCS-BRD284MD-1","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381410463834,"sku":"BWCS-BRD284MD-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381410496602,"sku":"BWCS-BRD284MD-3","price":118.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BRD284MD-1.webp?v=1778900597","url":"https:\/\/batteryweb.com\/products\/bard-medsystems-portascan-replacement-battery-12v-4500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
