Unitech 1400-900076G Li-Polymer Replacement Battery for MS633LR
Overview
The Unitech 1400-900076G is the OEM Li-Polymer replacement battery designed specifically for the Unitech MS633LR barcode scanner. Rated at 3.7V and 600mAh, this factory-new cell restores full runtime to MS633LR units that have degraded over charge cycles — a straightforward swap when productivity starts dropping due to shortened shift coverage. If you manage a pool of MS633LR scanners, keeping a spare 1400-900076G (sometimes searched as 1400 900076G) on the shelf avoids scanner downtime during peak periods.
Key Features
- Li-Polymer Chemistry (3.7V): Li-Polymer cells hold a stable voltage curve longer than older NiMH alternatives, meaning the scanner maintains consistent read performance through most of the discharge cycle rather than degrading early.
- 600mAh Capacity: Matches the original MS633LR factory specification — you get the same rated runtime the scanner was designed around, not a reduced-capacity substitute.
- OEM Part Number 1400-900076G: Direct fitment for the MS633LR; no modification or adapter required. Using the correct OEM part avoids fitment issues and connector compatibility problems that can arise with third-party alternatives.
- Lightweight at 0.06 lb: At under one tenth of a pound, the battery adds negligible weight to the handheld scanner — relevant when operators carry the device for extended periods.
Compatibility
This battery is specified for the Unitech MS633LR barcode scanner. Before ordering, confirm your scanner model matches — Unitech produces multiple scanner families across its barcode scanner lineup, and battery form factors are not interchangeable across models. If you are unsure which battery applies to your device, cross-reference the label on your existing battery or the MS633LR documentation.
For broader scanner fleet planning, reviewing a barcode scanner buying guide can help rationalize battery standardization across device families. Pairing spare batteries with a multi-bay charging cradle — available in scanner accessories — keeps your fleet rotation efficient.
Frequently Asked Questions
Q: What scanner is the 1400-900076G designed for?
A: The 1400-900076G is the replacement battery specified for the Unitech MS633LR barcode scanner.
Q: What are the electrical specs of the 1400-900076G?
A: It is a Li-Polymer cell rated at 3.7V with a capacity of 600mAh.
Q: Will this battery fit other Unitech scanner models?
A: This battery is specified for the MS633LR. Unitech scanner batteries are model-specific — verify compatibility before ordering for any other device.
Q: How much does the 1400-900076G weigh?

Q: Where is the 1400-900076G manufactured?
A: Country of origin is China (CN), as indicated on the product record.
The 1400-900076G is a direct OEM replacement — 3.7V Li-Polymer at 600mAh — which means you are restoring the MS633LR to its original factory-specified runtime, not accepting a compromise. When I see fleet managers try to stretch aging batteries past their useful cycle life, the symptom is always the same: scanners dropping off mid-shift, operators sharing devices, and warehouse throughput taking the hit at exactly the wrong time.
Technical Highlights:
- 600mAh OEM Capacity: Matches the MS633LR design spec exactly — no derating from a lower-capacity third-party substitute.
- Li-Polymer Chemistry: Stable 3.7V output through most of the discharge cycle, which keeps scanner RF and scan engine performance consistent rather than degrading as voltage drops.
- 0.06 lb Weight: Negligible impact on handheld ergonomics — relevant for operators running the scanner eight or more hours per day.
Deployment Considerations:
- Battery fitment is model-specific in the Unitech lineup — confirm your unit is the MS633LR before ordering. The part number 1400-900076G will not cross-fit to other Unitech scanner families.
- For high-utilization environments, order spare units and pair with a charging cradle so batteries rotate on a schedule rather than running to depletion, which extends overall cell longevity.
This battery is the right call for any operation running MS633LR scanners in continuous shift environments — distribution centers, receiving docks, or retail back-of-house — where an unplanned scanner outage has a direct labor cost.
