These handheld terminals are used in retail, logistics, and warehouse pick-and-pack operations. Capacity is 3000mAh (11.55Wh), matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEC50 and EC55 platform fit:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, connector pinout, and BMS handshake protocol — one pack covers the full EC50\/EC55 range, including the EC55AK-21B243-NA variant.\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 on the EC55 platform. The BMS responded correctly to trigger-inrush events and held the voltage rail steady through repeated wireless polling cycles without tripping into protective cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift installation tip:\u003c\/strong\u003e\n    After installing this pack, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. Scan-trigger inrush current is highest when the cell is near minimum charge — a pre-charged cell prevents false BMS trips during the opening minutes of a 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\"\u003eZebra EC50\/EC55 cradles authenticate the battery through the dock contacts before initiating a charge cycle. If contact resistance is too high — from handling residue or a light misalignment on seating — the cradle logs a charging error and refuses to charge. Wipe the gold contacts on the pack and the cradle dock with a dry lint-free cloth, then reseat the scanner firmly until it clicks. The cradle should clear the error and begin charging within 30 seconds of a clean reseat.\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\"\u003eOn the EC55 platform, the imager trigger and the Wi-Fi radio draw current simultaneously during a rapid scan burst — the combined inrush can pull the cell voltage below the BMS lower threshold momentarily. When this happens, the radio drops its connection to the access point while the imager continues to fire. This is not a radio fault — it is a voltage sag event. Confirm the pack is above 3.7V before a heavy scanning session; if sag persists at a full charge, the cell has degraded and a replacement is required.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324682862682,"sku":"BWCS-ZEC550BL-1","price":55.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43324682895450,"sku":"BWCS-ZEC550BL-2","price":64.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43324682928218,"sku":"BWCS-ZEC550BL-3","price":71.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZEC550BL-1.webp?v=1778122648","url":"https:\/\/batteryweb.com\/products\/zebra-ec50-replacement-battery-385v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
