It fits units cross-referencing part numbers 29518, 38403, 46607, 52030, C8872A, and EI-D-LI1. Connectors and BMS signalling match the original pack so the scanner recognises the cell on first boot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-part-number compatibility:\u003c\/strong\u003e\n    These OEM numbers span several Symbol scanner generations that share the same 7.4V power rail, connector pinout, and BMS handshake protocol. Swapping between them does not require firmware changes or reconfiguration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge, sustained scan-trigger loads, and USB data-transfer draws simultaneously. The BMS held regulation without tripping, and cell voltage stayed within the scanner's accepted window across all test conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eScanner decode-session care:\u003c\/strong\u003e\n    If the scanner is used in burst-scanning environments — rapid back-to-back reads on a conveyor line — let the pack cool for five minutes after heavy sessions before re-docking. Sustained decode cycles generate more heat than standard use, and charging a warm pack accelerates cell wear faster than any other single factor.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Symbol scanners report low battery immediately after a new pack is inserted\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSymbol handheld scanners map battery state against a stored voltage profile from the previous pack. When a new cell with different resting voltage characteristics is inserted, the scanner's fuel gauge reads the initial voltage against the old profile and flags it as low. This is not a fault with the replacement pack. Run the scanner through one full charge-to-discharge cycle and the device recalibrates its threshold to the new cell's actual curve. After that cycle, the percentage indicator will track correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner powers on but shuts off during USB data transfer to a PC\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUSB data transfer draws current from both the scanner's processor and its communication controller at the same time. If the pack voltage has sagged below approximately 6.8V under that combined load, the BMS trips the output to protect the cells before the OS-side transfer completes. The fix is to ensure the pack is above 7.2V before initiating a transfer session. Dock the scanner for a short charge first, then connect to the PC — the transfer will complete without a mid-session shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360794083418,"sku":"BWCS-LI1XL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360794116186,"sku":"BWCS-LI1XL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360794148954,"sku":"BWCS-LI1XL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LI1XL-1.webp?v=1778616260","url":"https:\/\/batteryweb.com\/products\/symbol-barcode-scanner-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
