The EDA40K is a rugged handheld terminal used in warehouse scanning, retail stock management, and field data collection. It replaces OEM part BAT-EDA40K directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEDA40K platform fit:\u003c\/strong\u003e\n    The EDA40K runs a fixed 3.85V battery rail with a proprietary BMS handshake over the connector. This pack matches that voltage rail and communicates correctly with the device firmware — the battery status indicator reads accurately from the first boot.\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 an EDA40K unit. The BMS reported state-of-charge correctly at each threshold, and the scan trigger inrush current at low cell voltage did not trip a false protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing this pack, seat the scanner in its charging cradle and run a complete charge cycle before deploying it. The scan trigger draws the highest inrush current when the cell is near minimum — starting the first shift on a full charge prevents the BMS from tripping on that spike mid-operation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the EDA40K drops wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe EDA40K fires both the imager and the Wi-Fi radio simultaneously during active scanning. Each scan burst plus the wireless polling cycle creates a combined inrush that briefly drags cell voltage. If the pack has degraded or is below 30% charge, the voltage sag crosses the BMS low-voltage threshold for long enough to force a radio reset. The result is a dropped Wi-Fi session that looks like a network fault but is a power delivery issue. Keeping the cell above 3.5V under load prevents this from occurring.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA charging error on the dock immediately after fitting a new pack is almost always contact resistance between the battery terminals and the cradle's charging pins — not a fault with the pack itself. Dust, warehouse residue, or a slight misalignment at insertion can break the circuit the dock uses to confirm a valid battery. Remove the scanner, wipe both the pack contacts and the cradle pins with a dry lint-free cloth, then reseat the scanner firmly until it clicks. If the error clears within 10 seconds of reseating, contact contamination was the cause.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324670345306,"sku":"BWCS-HYD410BL-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324670378074,"sku":"BWCS-HYD410BL-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324670410842,"sku":"BWCS-HYD410BL-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYD410BL-1.webp?v=1778121683","url":"https:\/\/batteryweb.com\/products\/honeywell-eda40k-replacement-battery-385v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
