The HS6578 is a linear imaging scanner used across retail, logistics, and warehouse pick-and-pack operations. Capacity matches the factory spec at 9.62Wh, so shift endurance stays consistent with what users expect from the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHS6578 platform fit:\u003c\/strong\u003e\n    The HS6578 uses a single-cell 3.7V Li-ion pack with a BMS that monitors cell voltage and temperature before enabling the scan trigger and wireless radio. This replacement matches the original connector pinout and BMS communication protocol, so the scanner powers on and authenticates normally without throwing a pack-fault error.\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 and wireless radio draw sequences on the HS6578. The BMS held stable through sustained burst scanning and did not trip under the combined inrush load of the imager and radio polling.\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 charging cradle and run a full charge cycle before pulling it for use. Scan-trigger inrush current peaks when the cell is near minimum voltage — a pre-charged cell prevents the BMS from tripping on the very first barcode read of the 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 a charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCharging errors on the HS6578 cradle are usually caused by high contact resistance between the dock pins and the battery terminals, not a fault in the pack itself. Oxidation or debris on the gold contacts breaks the voltage handshake the cradle uses to initiate charge. Wipe the battery contacts and the cradle pins with a dry lint-free cloth, then reseat the scanner firmly until it clicks. If the error clears, the pack is good — check cradle contacts routinely to keep resistance below the dock's threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner loses wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring fast sequential scanning, the imager and wireless radio draw current simultaneously, creating a combined inrush spike that can drag cell voltage below the BMS's cutoff threshold. When that happens, the radio drops first — the scanner stays on but loses its connection to the host before the imager resets. A cell with low state of charge makes this worse because internal resistance rises as voltage falls. Charge the pack to 4.2V before a high-throughput shift and the combined inrush stays within the BMS's operating window.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324908339290,"sku":"BWCS-LS3578BL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324908372058,"sku":"BWCS-LS3578BL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324908404826,"sku":"BWCS-LS3578BL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LS3578BL_1.webp?v=1778123334","url":"https:\/\/batteryweb.com\/products\/leuze-hs6578-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
