It replaces OEM part numbers BTRY-LS34IAB00-00 and 21-62606-01. These scanners are used in retail point-of-sale, warehouse picking, and inventory management — environments where scanner downtime directly stalls a shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLS3478 \/ DS3478 \/ LS3578 \/ DS3578 platform fit:\u003c\/strong\u003e\n    These four models share the same battery bay dimensions, 3.7V supply rail, and BMS handshake protocol. One pack covers the full group — no connector adapters or firmware differences to account for between them.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the LS3478 platform. The BMS handled scan-trigger inrush correctly without tripping into protection mode, and charge acceptance from the cradle was clean from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for pick-and-pack operations:\u003c\/strong\u003e\n    After installing a new pack, seat the scanner in its cradle and run a full charge before use. Scan trigger inrush is highest when cell voltage is near minimum — a pre-charged cell prevents false BMS trips during the first active 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\"\u003eSymbol cradles read the battery's BMS over the contact strip on the back of the pack. If those contacts are dirty or misaligned, the dock interprets the lack of communication as a fault and displays a charging error. This is not a defective battery — it is a contact resistance issue. Wipe the gold contacts on both the pack and the cradle slot with a dry cloth, reseat the scanner firmly, and confirm the charge indicator advances within 60 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 LS3478 and DS3578 run both the laser or imager and the wireless radio simultaneously during active scanning. A rapid scan burst spikes combined current draw — if the cell is partly discharged, voltage sag under that combined load can cause the radio module to drop its link before the BMS reaches cutoff. The fix is to avoid starting a high-volume scan session with the battery below roughly 3.5V. Charge the pack fully before any pick run that involves dense burst scanning or extended wireless polling.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324909224026,"sku":"BWCS-LS3578BL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324909256794,"sku":"BWCS-LS3578BL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324909289562,"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\/symbol-ls3478-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
