These are cordless laser and imager scanners used in retail point-of-sale, warehouse pick-and-pack, and inventory workflows. Capacity is 2200mAh (8.14Wh) — matched to the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLS3478 \/ DS3578 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One pack covers both the corded-style LS3478 and the Bluetooth DS3578 — the radio draw on the DS variants slightly increases current demand per scan cycle, but the cell chemistry handles both load profiles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack in an LS3478 cradle and a DS3578 Bluetooth unit. The BMS accepted charge from both single-bay and multi-bay cradles without fault codes. Scan trigger inrush current stayed within cutoff thresholds across all test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep on the cradle:\u003c\/strong\u003e\n    After installing, seat the scanner in its charging cradle and run a full charge cycle before use. Scan trigger inrush current peaks when the cell is near minimum — a fully charged pack prevents false BMS trips at the start of the first 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\"\u003eMulti-bay cradles used in high-throughput warehouses build up oxidation and debris on the charging contacts over time. A new pack with clean contacts sitting against dirty dock contacts creates enough resistance to trigger a charging fault. Wipe the battery contacts and the cradle dock pins with a dry cloth, then reseat the scanner firmly. The fault clears on the next charge attempt once contact resistance drops back into range.\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 DS3578 runs a Bluetooth radio and a laser or imager simultaneously during fast scan sequences. The combined inrush from both the radio polling cycle and the scan trigger can cause a momentary voltage sag on a degraded or undercharged cell, which the BMS reads as an overcurrent condition and trips. This is not a scanner firmware issue — it is a cell-state issue. Charge the pack to full before the shift and confirm the cradle LED shows a complete charge, not just a partial top-up.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324917743706,"sku":"BWCS-LS3478BL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324917776474,"sku":"BWCS-LS3478BL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324917809242,"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\/symbol-ls3478-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
