It restores full scanning capability to terminals used in warehouse, logistics, and point-of-sale environments. Swap it in when the original cell no longer holds a charge through a full shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHP 4400W platform fit:\u003c\/strong\u003e\n    The 4400W runs a 3.7V single-cell architecture with a direct BMS handshake to the host terminal. This replacement pack matches that voltage rail and connector footprint, so the device recognises the battery and enables the scan trigger without prompts.\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 4400W terminal. The BMS reported accurate state-of-charge, the scan trigger fired without fault codes, and the wireless radio maintained its polling interval throughout the test cycle.\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 run a full charge cycle before committing it to a pick-and-pack shift. The inrush current from the scan trigger is highest when the cell sits near minimum — a fully charged pack prevents false BMS trips during that first burst of scanning activity.\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\"\u003eCharging errors on a fresh pack almost always come down to contact resistance between the battery terminals and the cradle's charging pins. Dust, warehouse grime, or residue from the old pack coats the contacts and the cradle interprets the high resistance as a fault. Wipe the battery contacts and the cradle pins with a dry cloth before reseating. If the error clears within 30 seconds of reseating, contact resistance was the cause — not a faulty pack.\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 4400W draws current simultaneously from the wireless radio and the scan trigger during rapid scanning. When the cell voltage sags under that combined load, the radio drops its connection before the scanner shows any low-battery warning. This is a load-sag symptom, not a firmware issue. Charge the pack to 100% before the shift and check that the terminal's RF polling interval is set to the recommended value — a shorter polling interval compounds the draw and accelerates the sag.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324850995290,"sku":"BWCS-GM410BX-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324851028058,"sku":"BWCS-GM410BX-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324851060826,"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\/hp-4400w-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
