It fits the BlueBird BP30 and BM180 handheld barcode scanners. Voltage and cell format match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBP30 and BM180 platform fit:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, 3.7V power rail, and BMS handshake protocol. The BAT-BP30-45 form factor — 59.80 × 46.10 × 7.20mm — seats flush in either unit without modification to contacts or housing clips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a BP30 unit. The BMS accepted the cell without fault codes, held the charge curve within spec, and triggered the low-voltage cutoff at the correct threshold during drain testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, place the scanner in its cradle for a full charge cycle before picking up the first shift. Scan trigger inrush current is highest when the cell is near minimum charge, and starting with a full pack prevents false BMS trips during the first burst of rapid scanning.\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  \u003cp class=\"bpw-desc-p\"\u003eA charging error on a freshly installed battery is almost always a contact resistance issue, not a faulty cell. Dock contacts accumulate oxidation and debris from everyday handling, and a new pack with slightly different contact pressure can expose that resistance. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then reseat the scanner firmly until the dock clicks. If the error clears within 30 seconds, contact resistance was the cause — the pack is fine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring a rapid scan sequence, the imager and the wireless radio draw current simultaneously. On a depleted or degraded cell, this combined inrush causes a momentary voltage sag that drops below the radio module's minimum operating threshold, triggering a connection drop. The scanner may reconnect automatically within a few seconds, but the root cause is the pack voltage sagging under combined load. Start each shift with a fully charged battery — the sag at full charge stays above the radio's 3.2V minimum even under peak combined draw.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324713730138,"sku":"BWCS-BUP180BL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324713762906,"sku":"BWCS-BUP180BL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324713795674,"sku":"BWCS-BUP180BL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BUP180BL-1.webp?v=1778122617","url":"https:\/\/batteryweb.com\/products\/bluebird-bp30-replacement-battery-37v-2000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
