It fits the GM4100, GM4130, GM4400, and GM4430 models used in retail, warehousing, and logistics operations. The cell matches the original pack's voltage rail and connector spec to keep your scanner running through full shifts.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGM4100 \/ GM4400 series compatibility:\u003c\/strong\u003e\n    These four models share the same battery bay geometry, 3.7V nominal rail, and BMS handshake protocol. One cell fits all — no adapter or firmware change required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated scan-burst loads on the GM4100 platform. The BMS held stable through rapid trigger inrush events and maintained correct charge termination in both cradle and USB charge modes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep on pick-and-pack lines:\u003c\/strong\u003e\n    After installing this pack, seat the scanner in its cradle and run a full charge cycle before pulling it for use. Scan trigger inrush current peaks when the cell is near minimum — a full charge before the first shift prevents false BMS trips at the start of a 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  \u003cp class=\"bpw-desc-p\"\u003eDock contact resistance is the most common cause of charging errors when fitting a new battery in the GM4100 series cradle. Oxidation or debris on the gold contacts breaks the low-voltage handshake the dock uses to start a charge cycle. Wipe the pack's contact pads and the cradle contacts with a dry lint-free cloth, then reseat the scanner firmly. If the error clears, the pack was good — the dock contacts were the problem.\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 GM4100 draws simultaneously from the wireless radio and the scan trigger during fast barcode reads — both loads hit the cell at the same time. If the pack's state of charge is low, this combined inrush causes a momentary voltage sag that the BMS reads as an under-voltage fault, dropping the wireless link. Recharge the pack before using the scanner in high-frequency scan environments. If the drop-outs continue with a fully charged pack, check that the battery contacts are seated flush — a loose fit adds contact resistance and worsens sag.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324852011098,"sku":"BWCS-GM410BX-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324852043866,"sku":"BWCS-GM410BX-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324852076634,"sku":"BWCS-GM410BX-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GM410BX-1.webp?v=1778123165","url":"https:\/\/batteryweb.com\/products\/datalogic-gm4100-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
