It replaces OEM part BAT-BP30-45 directly. Both scanners are used in retail and warehousing environments where all-day mobile scanning matters.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBP30 and BM180 compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V battery bay, connector pinout, and BMS handshake protocol. A single pack covers either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the BP30's BMS initialisation cycle. The protection circuit recognised the cell correctly, accepted charge input from the cradle, and passed the scanner's self-test without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and let it complete a full charge cycle before the shift begins. The scan trigger draws an inrush current spike at low cell voltage — a pre-charged pack prevents the BMS from tripping on that first burst in a pick-and-pack run.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eBlueBird cradles use contact-based charging with no magnetic assist. If dock contacts or pack contacts have oxidation or residue, resistance rises enough that the cradle firmware logs a charge fault and stops the session. This is not a cell defect — it is a contact issue. Wipe the gold contacts on both the pack and the cradle slot with a dry lint-free cloth, reseat the scanner firmly, and the fault clears in most cases. If the cradle LED still shows an error, check that the pack is seated flush and that the bay latch has clicked.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner not reading barcodes after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a new pack is installed at partial charge, the imager or laser module may not receive enough voltage to fire at full power — the BP30 prioritises system logic over peripheral draw when voltage is low. The scanner will appear to power on and respond to the trigger, but the read rate drops sharply or stops entirely. Charge the pack fully in the cradle before the first use session. The BP30's imager requires a stable rail above 3.5V to decode reliably, so let the cell reach full charge before putting the unit into active scanning.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324770680922,"sku":"BWCS-BUP300BL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324770713690,"sku":"BWCS-BUP300BL-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324770746458,"sku":"BWCS-BUP300BL-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BUP300BL_1.webp?v=1778123055","url":"https:\/\/batteryweb.com\/products\/bluebird-bp30-replacement-battery-37v-3900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
