Unitech 1400-900057G EA630 Replacement Li-ion Battery Pack
Overview
The Unitech 1400-900057G is the factory-specified 3.85V 4000mAh Li-ion battery pack designed for the EA630 mobile computer. If your EA630 units are dropping off shift before the work is done — or you're rotating out a degraded original pack — this is the exact replacement to stock. At 0.5 lb and a compact 3.5 x 2.0 in footprint, it swaps directly into the EA630 without modification. This listing covers the 1400-900057G (also searched as 1400 900057G), part of the Unitech mobile computer accessories lineup.
Key Features
- 4000mAh Capacity: A full 4000mAh rating means a single charge supports a demanding warehouse or logistics shift. Higher-capacity packs reduce how often workers need to return to a charging station, which matters in large-footprint facilities.
- 3.85V Li-ion Chemistry: Lithium-ion at 3.85V delivers a stable discharge curve — voltage stays consistent across most of the discharge cycle rather than sagging early, so the EA630's performance remains predictable from first scan to last.
- 0.5 lb Weight: At half a pound, the battery adds minimal load to the EA630 handset. Workers carrying the device for a full shift won't notice additional fatigue compared to the OEM pack.
- Compact 3.5 x 2.0 in Form Factor: Dimensioned to fit the EA630 battery bay exactly — no adapters, no fitment guesswork. This matters when you're stocking spares across a fleet of units.
- Factory-New Genuine Pack: Sourced as a genuine Unitech component, not a third-party cell repack. Counterfeit or grey-market batteries can underreport capacity, cycle poorly, or trigger battery warnings in managed device software.
- Fleet-Ready Spare Strategy: Stocking spares of the 1400-900057G enables a hot-swap approach — depleted packs go on the charger while fresh ones keep devices in the field. This is standard practice in mobile computer deployments running two or three shifts.
Integration and Compatibility
The 1400-900057G is built for the Unitech EA630 mobile computer. Before ordering, confirm your EA630 unit accepts this battery SKU — Unitech has released multiple EA630 variants, and battery compatibility should be verified against your specific device revision. If you're evaluating the EA630 platform itself or need additional accessories, review the full Unitech catalog for compatible charging cradles and protective cases. For multi-shift operations, pairing this battery with a multi-bay charging dock gives you a managed rotation cycle without downtime.
Frequently Asked Questions
Q: What device is the 1400-900057G compatible with?
A: The 1400-900057G is the specified battery pack for the Unitech EA630 mobile computer. Verify your EA630 hardware revision before ordering to confirm battery bay compatibility.
Q: What is the battery capacity and voltage of the 1400-900057G?
A: The 1400-900057G is a 4000mAh Li-ion cell rated at 3.85V — the factory-specified configuration for the EA630 platform.
Q: Does the 1400-900057G ship factory-new?
A: Yes. The 1400-900057G ships as a factory-new, genuine Unitech component — not a third-party cell repack or refurbished unit.
Q: What is the weight of the 1400-900057G battery pack?
A: The battery weighs 0.5 lb, consistent with the OEM pack it replaces in the EA630.
Q: Is there a warranty on the 1400-900057G?
A: The 1400-900057G carries a manufacturer warranty. Contact the vendor at time of purchase to confirm current warranty terms for this SKU.
The 1400-900057G runs at 3.85V with a 4000mAh Li-ion cell — that's the factory-rated capacity for the EA630, and it's the number that drives your spare battery calculation for multi-shift operations. If your facility runs two 10-hour shifts, one spare per device is typically the minimum; three-shift environments should budget two spares per unit and a charging dock sized accordingly.
Technical Highlights:
- 4000mAh Li-ion: Full-shift runtime at the EA630's rated draw. Li-ion chemistry avoids the memory effect that degrades NiMH packs over repeated partial charges — relevant in environments where workers top off opportunistically rather than running full discharge cycles.
- 3.85V Nominal Voltage: Matches the EA630's power rail spec exactly. Off-spec voltage from grey-market packs can cause erratic device behavior or premature low-battery warnings mid-shift.
- 0.5 lb / 3.5 x 2.0 in: Dimensionally identical to the OEM battery — critical when you're ordering spares sight-unseen for a fleet. A fitment mismatch on 50 units is a costly problem to return-ship.
Deployment Considerations:
- If your EA630 fleet is managed through an MDM platform, confirm the battery management thresholds are calibrated to a 4000mAh cell — some MDM tools track capacity and flag mismatches if the reported spec differs from the enrolled baseline.
- Country of origin is CN (China). If your procurement policy includes supply-chain sourcing restrictions, verify this against your purchasing guidelines before committing to volume.
The 1400-900057G is the right stock item for distribution centers and field service operations running EA630 devices across extended shifts — buy to the number of devices in your fleet, not one-for-one, and build in at least a 20% buffer for units in the charging rotation at any given time.
