It replaces OEM part numbers BT-47, 128004721, TW18050652, and RBP-GM45. Connector, BMS handshake, and physical form factor match the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGM4500 and GBT4500 platform fit:\u003c\/strong\u003e\n    Both corded and Bluetooth variants of the Gryphon 4500 run on the same 3.7V single-cell architecture. The BMS handshake protocol is identical across the platform, so one pack covers both scanner types without firmware conflicts.\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 and wireless polling sequences on a GBT4500 unit. The BMS held charge cutoff at 4.2V and low-voltage protection tripped cleanly at 3.0V with no false shutdowns during rapid scanning.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift cradle protocol:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle for a full charge cycle before pulling it into pick-and-pack operations. The scan trigger draws the highest inrush current when the cell is near minimum, and a fully charged pack prevents false BMS trips on the opening 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\n  \u003cp class=\"bpw-desc-p\"\u003eCharging docks for the Gryphon 4500 sense current flow through spring-loaded contacts on the scanner base. Even minor oxidation or debris on those contacts raises resistance enough for the dock to flag a fault and refuse to charge. This is not a cell defect — it is a contact handshake failure. Remove the scanner, wipe the gold contacts on both the pack and the dock with a dry cloth, then reseat firmly. If the error clears, the circuit is complete and charging will proceed normally.\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\"\u003eThe GBT4500 runs its Bluetooth radio and imager from the same 3.7V cell simultaneously. During rapid scan sequences, the combined inrush from the imager trigger and the radio transmit pulse can momentarily sag cell voltage below the radio's minimum operating threshold, dropping the wireless link. This is most common when the battery is below 20% charge. The fix is straightforward: keep the pack above 3.6V during high-volume scan shifts by rotating charged spares at the cradle rather than running cells to cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324737454170,"sku":"BWCS-DAT470BL-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324737486938,"sku":"BWCS-DAT470BL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324737519706,"sku":"BWCS-DAT470BL-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DAT470BL-1.webp?v=1778123055","url":"https:\/\/batteryweb.com\/products\/datalogic-gryphon-4500-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
