The MC20 is a handheld barcode scanner used in retail, warehousing, and logistics environments. It drops directly into the battery bay and connects via the same multi-pin dock interface as the OEM unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMC20 platform fit:\u003c\/strong\u003e\n    The MC20 uses a single-cell Li-ion architecture at 3.7V nominal. The BMS handshake operates over a dedicated sense line in the connector — this pack carries the same resistor ID the dock and device firmware expect, so the charge controller accepts it without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on the MC20 platform. The BMS held voltage within spec across scan trigger and wireless radio draw combined, with no mid-cycle cutoff events recorded.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep on the MC20:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle for a complete charge cycle before starting pick-and-pack. The scan trigger inrush current spikes hardest when the cell is near minimum — a fully charged pack prevents the BMS from tripping on the first burst of the 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\"\u003eThe MC20 cradle reads pack identity through the contact array on the battery face. If the dock contacts are oxidised or the pack is seated at a slight angle, contact resistance rises high enough that the charger IC logs a fault rather than initiating a charge cycle. Wipe the gold contacts on both the pack and the cradle with a dry cloth, then firmly reseat the scanner until you feel the retention click. The charge LED should shift from fault amber to solid green within a few seconds of clean contact.\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 MC20 pulls current simultaneously from the imaging engine and the wireless radio during a rapid scan sequence. If the cell voltage sags below the radio module's minimum threshold — typically around 3.2V under combined load — the wireless stack drops before the BMS triggers a full cutoff. This causes the scanner to lose its pairing mid-burst while the imager still fires. A full charge before the shift keeps the cell well above that sag threshold; if drops persist on a charged pack, check that no other process is polling the radio at an elevated rate in the device config.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324687712346,"sku":"BWCS-ZBR200BL-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324687745114,"sku":"BWCS-ZBR200BL-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324687777882,"sku":"BWCS-ZBR200BL-3","price":100.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZBR200BL-1.webp?v=1778122647","url":"https:\/\/batteryweb.com\/products\/zebra-mc20-replacement-battery-37v-3300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
