It replaces OEM part numbers 0400-0066, 0400-0121, and 0570-0066. The BladderScan uses this cell to power its ultrasonic transducer, display, and onboard processing during non-invasive bladder volume assessments.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e9400 BladderScan and BVI 9400 fit:\u003c\/strong\u003e\n    Both models share the same 11.1V three-cell Li-ion configuration, physical form factor, and BMS handshake protocol. A single replacement covers either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the BladderScan's full power-on self-test sequence. The BMS negotiated correctly, accepted a full charge, and delivered stable voltage across the device's scan and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full startup self-test without interruption. Medical-grade BMS firmware runs a verification pass at boot — cutting power mid-sequence logs 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\"\u003eBladderScan charge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BladderScan's charge IC applies a conservative current ceiling when it detects a new or previously unrecognised cell. On the first charge, it holds the termination threshold lower than the OEM cell's calibrated limit. The display may stop at 90–95% and show a full indicator despite the cell not being at true capacity. Running one complete charge-to-discharge cycle recalibrates the charge IC and allows subsequent charges to reach the correct 12.6V termination point.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off unexpectedly during a scan after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring the first several cycles, new Li-ion cells have not yet reached full electrolyte wetting across all layers, which causes momentary voltage sag under the BladderScan's transducer firing load. The BMS reads this sag as a low-voltage event and triggers a protective shutdown before the cell is truly depleted. This is not a fault in the replacement — it resolves after approximately 10 full charge-discharge cycles as the cell reaches stable internal resistance. Until then, confirm the battery is charged to 12.6V before beginning a clinical session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381361934426,"sku":"BWCS-VRH940MX-1","price":178.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381361967194,"sku":"BWCS-VRH940MX-2","price":212.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381361999962,"sku":"BWCS-VRH940MX-3","price":237.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VRH940MX-1.webp?v=1778900304","url":"https:\/\/batteryweb.com\/products\/verathon-9400-bladderscan-replacement-battery-111v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
