It matches OEM part number 1400-900057G and fits the same battery bay with the same connector orientation. Capacity is sourced from the product specification, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEA630 and EA630 Plus compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, voltage rail, and BMS handshake protocol. The EA630 Plus carries the same 3.85V nominal requirement, so one pack covers both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on EA630 hardware. The BMS accepted the cell without fault codes, and the scanner's OS recognised the battery state correctly across the full charge window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation for pick-and-pack use:\u003c\/strong\u003e\n    Place the scanner in its cradle for a complete charge cycle before the first shift. Scan trigger inrush current peaks when the cell is near minimum voltage — a fully charged pack prevents false BMS trips at the start of a high-volume picking run.\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 after installing a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCharging docks on the EA630 series read battery state through pogo-pin contacts on the underside of the pack. If those contacts have oxidation, residue from the previous battery, or uneven seating, the dock reports a fault before current ever flows. Wipe the gold contacts on the pack and the dock with a dry cloth, then reseat firmly until the dock LED changes state. If the error persists, the dock itself may have a bent contact pin — check under magnification before assuming the pack is at fault.\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 EA630 draws current simultaneously from the imager and the wireless radio during a rapid scan sequence. When both subsystems pull at the same time, instantaneous current demand spikes well above the average draw. A degraded or deeply discharged cell cannot hold voltage through that combined inrush, and the radio subsystem — which has a lower minimum operating voltage than the imager — drops off first. Charge the pack to full before a high-frequency scan shift, and check that cell voltage under no-load reads at least 3.85V before deployment.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324661399642,"sku":"BWCS-UPA630BL-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324661432410,"sku":"BWCS-UPA630BL-2","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324661465178,"sku":"BWCS-UPA630BL-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UPA630BL-1.webp?v=1778121712","url":"https:\/\/batteryweb.com\/products\/unitech-ea630-replacement-battery-385v-3900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
