It replaces OEM part numbers 001647-U and 10N-4000AA. The PIC30 series runs on AC in fixed locations and switches to this battery during patient transport or when wall power is unavailable.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePIC30 \/ PIC40 \/ PIC50 platform fit:\u003c\/strong\u003e\n    These three monitors share the same battery bay dimensions, voltage rail, and connector pinout. The BMS in each unit applies the same NiMH charge profile and reports state-of-charge identically, so one cell SKU covers the full series without modification.\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 on a PIC30 unit. The BMS accepted the cell on first insertion, completed charge without fault flags, and the state-of-charge readout stabilised after one full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the PIC30 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this sequence registers a 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\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PIC30 runs a hardware and BMS verification check during every startup. If the incoming cell voltage is below approximately 10.8V — common after storage — the BMS interprets it as a degraded or incompatible cell and halts the boot sequence before the main UI loads. This is not a fault with the replacement battery. Connect the device to AC power and allow it to charge the new cell for a minimum of two hours before attempting a battery-only boot. Once voltage recovers above threshold, the self-test completes normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PIC30 charge IC applies a conservative current limit on cells it has not yet profiled. On the first charge cycle with a new cell, the indicator may plateau at 85–90% and stall. This is the charge controller applying a reduced termination threshold until it establishes a baseline for the cell's internal resistance. Run one complete charge-discharge cycle with the device connected to AC, then repeat the full charge. The indicator reaches 100% consistently from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381481570394,"sku":"BWCS-WB300MD-1","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381481603162,"sku":"BWCS-WB300MD-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381481635930,"sku":"BWCS-WB300MD-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WB300MD-1.webp?v=1778901194","url":"https:\/\/batteryweb.com\/products\/welch-allyn-pic30-replacement-battery-12v-3700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
