Capacity is 2200mAh (8.14Wh), matching the original power budget for sustained scan and wireless operation. It fits the HS6578 body with the same connector orientation and BMS communication profile as the factory pack.\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 architecture with a proprietary BMS handshake through the dock connector. This pack carries the same handshake logic, so the cradle and host device recognise the battery at startup without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through rapid scan bursts combined with concurrent wireless polling — the BMS held stable across both inrush events without triggering low-voltage cutoff during the combined draw spike.\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 the first pick-and-pack shift. Scan trigger inrush is highest when the cell is near minimum, and a fully charged pack prevents false BMS trips when the first shift hits continuous scan demand.\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\"\u003eThe HS6578 cradle reads battery state through gold-pin contacts on the base of the scanner. Dust, warehouse grime, or oxidation on those contacts raises resistance enough that the dock reports a fault instead of initiating charge. This is not a cell fault — it's a contact issue. Wipe the contacts on both the pack and the dock with a dry cloth, reseat firmly, and the cradle should begin the charge cycle within 10 seconds.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner dropping wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HS6578 draws simultaneously from the radio module and the scan trigger during a burst scan sequence. When the cell voltage sags below approximately 3.4V under that combined load, the radio stack loses enough supply to maintain its polling interval and drops the connection. This is most common late in a shift when the pack is partially depleted. Topping up the pack before a high-volume picking window eliminates the voltage sag that causes the drop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324919611482,"sku":"BWCS-LS3478BL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324919644250,"sku":"BWCS-LS3478BL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324919677018,"sku":"BWCS-LS3478BL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LS3478BL-1.webp?v=1778123427","url":"https:\/\/batteryweb.com\/products\/leuze-hs6578-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
