It fits the Marathon handheld barcode scanner used across retail, warehousing, and logistics operations. Replaces OEM part numbers 163878-0001, FX1382, and FX1381.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMarathon Data Terminal platform fit:\u003c\/strong\u003e\n    All three OEM part numbers — 163878-0001, FX1382, and FX1381 — share the same 11.1V cell configuration, connector pinout, and BMS handshake protocol. Swapping between them does not require firmware changes or reconfiguration on the host device.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated scan-burst loads and monitored BMS response at both low-state-of-charge and full-charge transitions. The protection circuit held steady across repeated trigger inrush events without nuisance trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing the new pack, seat the terminal in its charging cradle and run a full charge cycle before putting it into pick-and-pack rotation. Scan trigger inrush current peaks when the cell is near minimum — starting the first shift on a fully charged pack prevents the BMS from tripping on that initial load spike.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThe Marathon's charging dock reads battery status through a set of spring-loaded contact pins. Oxidation or debris on either the dock pins or the battery's contact pads raises contact resistance high enough that the charger's handshake fails and throws an error. This is not a battery fault — it is a connection fault. Wipe both the dock pins and the battery contacts with a dry lint-free cloth, then reseat the pack firmly. The charger should begin its normal charge sequence within a few seconds of clean contact being established.\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\"\u003eDuring a fast scan burst, the Marathon fires both the imager and its wireless radio in tight succession. That combined inrush can cause a momentary voltage sag on an aging or partially discharged cell, which the radio interprets as a power fault and drops the connection. A new pack at full charge raises the cell's internal impedance headroom, reducing sag depth under the same combined load. If drop-outs persist with the new pack fully charged, check that the device's wireless polling interval is not set to maximum — back it off one step and retest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324681945178,"sku":"BWCS-LMX138BL-1","price":148.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324681977946,"sku":"BWCS-LMX138BL-2","price":172.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324682010714,"sku":"BWCS-LMX138BL-3","price":190.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LMX138BL-1.webp?v=1778121683","url":"https:\/\/batteryweb.com\/products\/lxe-marathon-data-terminal-replacement-battery-111v-5580mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
