It replaces OEM part numbers BT-47, 128004721, TW18050652, and RBP-GM45. If your scanner is shutting down mid-shift or failing to hold a charge, this cell is a direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGryphon 4500 \/ GM4500 \/ GBT4500 platform fit:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell covers the entire lineup without firmware or hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated scan-trigger bursts combined with active Bluetooth polling. The BMS held stable across inrush spikes and did not trip false low-voltage cutoffs during the combined radio-plus-trigger draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift cradle protocol:\u003c\/strong\u003e\n    After installing this pack, seat the scanner in its cradle and run a full charge cycle before deploying on the floor. Scan trigger inrush current peaks when the cell is near minimum voltage — a fully charged cell prevents false BMS trips on the first pick-and-pack shift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gryphon cradle reads pack state through gold contact pads on the battery base. If those pads have oxidation, adhesive residue, or shipping film, the dock sees elevated contact resistance and flags a charging fault. Remove the pack, wipe the contacts on both the battery and cradle with a dry lint-free cloth, and reseat firmly. If the error clears within 30 seconds of reseating, contact resistance was the cause — not the cell itself.\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\"\u003eBack-to-back scans and active Bluetooth polling pull simultaneously from the same cell. At high burst frequency, a degraded or low-charge pack can sag below the radio module's minimum operating voltage, dropping the wireless link mid-session. The scanner often recovers and reconnects within seconds, which makes this look like a signal issue rather than a battery issue. Check pack state before a shift — if the indicator shows less than two bars, seat it in the cradle before use rather than running it down further.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324707373146,"sku":"BWCS-DAT470BX-1","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324707405914,"sku":"BWCS-DAT470BX-2","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324707438682,"sku":"BWCS-DAT470BX-3","price":68.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DAT470BX-1.webp?v=1778122617","url":"https:\/\/batteryweb.com\/products\/datalogic-gryphon-4500-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
