Unitech 1400-900063G EA520 Battery 3.85V 4250mAh
Overview
The Unitech 1400-900063G is an OEM lithium-ion battery rated 3.85V nominal, 4250mAh — a direct replacement cell for the Unitech EA520 mobile computer family. The 4250mAh capacity supports 8–12 hour field shifts running barcode capture, WMS integration, and inventory workflows in warehouse, logistics, and retail environments. This is the battery to stock when your EA520 units are aging or when you need spares for multi-shift operations without swapping devices or interrupting work cycles.
Compatibility
This battery is purpose-built for the Unitech EA520 mobile computer line only. Confirm your handheld is stamped EA520 or check its product documentation before ordering — the connector type and 3.85V specification are fixed to this model family. Other Uniteth mobile devices may use different battery part numbers even if they appear physically similar. Installing a non-compatible battery risks device damage or failure to charge.
Installation Notes
Replacement is straightforward: power down the EA520 completely, locate the battery compartment (typically on the back or underside of the device), release the latch or clip, slide out the depleted battery, and insert the new 1400-900063G unit until it clicks. Ensure the connector contacts align — misalignment prevents charging. Allow 2–3 hours on a standard charger for a full recharge cycle. Store unused batteries in a cool, dry location and avoid dropping or crushing the cell — lithium cells are sensitive to physical stress and can fail or degrade if impacted.
