It replaces OEM part numbers BTRY-MC55EAB02, 82-111094-01, and U60493. The battery slots into the same compartment as the original and uses the same connector and contact layout.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMC55 \/ MC65 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay geometry, contact pin arrangement, and BMS handshake protocol. One pack covers the full MC55 and MC65 lines without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on an MC55A unit, running combined scan trigger and 802.11b\/g wireless polling. The BMS held stable across charge and discharge, with no protection cutoff trips during normal scan bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation on pick-and-pack lines:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and run a full charge cycle before deploying it on the floor. Scan trigger inrush current is highest when the cell is near minimum voltage — a fully charged pack prevents false BMS trips during the first heavy scan 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 charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA charging error on the dock does not always mean a faulty battery. Cradle contacts on the MC55 accumulate oxidation and debris from warehouse floors, which raises contact resistance enough for the dock to flag a fault. Remove the scanner, wipe the gold contacts on both the battery and the cradle with a dry cloth, then reseat firmly. If the error clears within 30 seconds of reseating, contact resistance was the cause — not the cell.\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 MC55 runs its 802.11 radio and scan engine simultaneously, and the combined inrush during a rapid scan burst pulls more current than either subsystem does alone. If the cell voltage sags below the radio's minimum rail during that combined draw, the wireless session drops mid-scan. This is more common when the battery is below 20% state of charge. Keep the pack above that threshold during shifts, and the radio will hold its connection through sustained scanning.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324794994778,"sku":"BWCS-MC550BX-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324795027546,"sku":"BWCS-MC550BX-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324795060314,"sku":"BWCS-MC550BX-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MC550BX-1.webp?v=1778123184","url":"https:\/\/batteryweb.com\/products\/symbol-mc55-replacement-battery-37v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
