Socket Mobile AC4146-1904 AA NiMH Battery for SocketScan
Overview
The Socket Mobile AC4146-1904 is an AA NiMH rechargeable battery engineered as a direct replacement power source for Socket Mobile SocketScan handheld barcode scanners. This battery supports extended field operations and mobile data capture workflows across retail, warehouse, and logistics environments. The AC4146-1904 (often searched as AC4146 1904) integrates seamlessly with Socket Mobile's 1D/2D scan engine systems, enabling operators to sustain scan productivity throughout multi-hour shifts without relying on disposable alkaline batteries—a cost and waste reduction measure meaningful across fleets of 10+ devices.
Key Features
- NiMH Chemistry: Rechargeable composition reduces per-scan power cost compared to single-use batteries. Over a scanner's lifespan, recharging AC4146-1904 units typically cuts battery expense by 60–70%, a real lever on large deployments where scanners run 5–8 hours daily.
- AA Form Factor: Standard cylindrical geometry fits Socket Mobile SocketScan models designed for AA battery slots. Verify your specific scanner revision supports NiMH chemistry before ordering, as some older variants may require alkaline-only designs.
- Field-Proven Compatibility: Direct fit for Socket Mobile SocketScan barcode scanner series. Organizations running multiple scanning devices benefit from standardized, interchangeable power supplies across sites—simplifies procurement and reduces SKU sprawl in inventory.
- Rechargeable Runtime: NiMH batteries maintain stable voltage during discharge, delivering consistent scan-engine performance across the battery's operational window. Voltage sag is minimal until near end-of-life, so scan quality remains steady, unlike alkaline batteries that degrade gradually.
- Environmental & Storage Efficiency: Eliminates disposable battery waste from daily operations. Organizations managing 50+ scanners reduce hazardous waste streams and associated disposal costs—a sustainability metric increasingly tracked in corporate procurement scorecards.
- Low Self-Discharge (Typical): Modern NiMH formulations hold charge for weeks when idle, reducing the need to top off batteries between shifts. Useful for intermittent-use scanners (e.g., seasonal warehouse spikes) that sit dormant for days.
Integration & Compatibility
The AC4146-1904 is compatible with Socket Mobile SocketScan barcode scanner models that use AA battery form factor. Confirm your specific scanner model supports AA NiMH batteries before ordering—some SocketScan variants are optimized for alkaline only and may not deliver full runtime on rechargeable chemistry. Consult the scanner's user manual or contact Socket Mobile support to verify compatibility. Organizations deploying mixed SocketScan generations should test the AC4146-1904 in each model revision to ensure consistent performance across the fleet.

When to Choose a Different Model
If your SocketScan model is rated for alkaline batteries only, do not use the AC4146-1904. Conversely, if you operate handheld scanners from other manufacturers (e.g., Zebra, Honeywell, Datalogic), verify Socket Mobile battery compatibility before purchase. If you require extended runtime beyond a single rechargeable AA charge, consider deploying spare charged AC4146-1904 units at scanning stations or investing in a spare scanner battery compartment.
Frequently Asked Questions
Q: Is the AC4146-1904 a direct drop-in replacement for alkaline AA batteries in my SocketScan?
A: In most Socket Mobile SocketScan models designed for AA batteries, yes—the AC4146-1904 fits the same slot. However, voltage and chemistry differ: NiMH batteries deliver 1.2V nominal vs. 1.5V for alkaline, and some older scanner firmware may not recognize or optimize for rechargeable chemistry. Always verify your scanner model supports AA NiMH batteries before deployment.
Q: How many recharge cycles does the AC4146-1904 support?
A: Typical NiMH AA batteries support 500–1,000 charge cycles depending on charging method and discharge depth. Socket Mobile does not publish cycle-life data for the AC4146-1904 specifically in the available evidence. Contact Socket Mobile support for confirmed cycle-life specifications.
Q: Can I use the AC4146-1904 in non-Socket Mobile devices?
A: The AC4146-1904 is a generic AA NiMH cell and will physically fit any AA-slot device. However, it is spec'd and warranted only for Socket Mobile SocketScan barcode scanners. Use in other brands or models is outside the scope of Socket Mobile support.
Q: What is the typical shelf life of an unused AC4146-1904?
A: NiMH batteries self-discharge at roughly 15–20% per month when idle. Store the AC4146-1904 in a cool, dry place and expect to top off the charge every 3–4 months if the battery sits unused. For long-term storage (6+ months), store uncharged or partially charged in a sealed container.
Q: Is a charger included with the AC4146-1904?
A: No charger is included. The AC4146-1904 requires an external AA NiMH charger compatible with Socket Mobile SocketScan scanner charging docks or a standalone AA battery charger. Verify that any external charger supports NiMH chemistry and that your scanner's charging cradle is rated for rechargeable batteries.
Q: How does the AC4146-1904 perform in cold environments?
A: NiMH batteries experience reduced runtime and voltage stability in cold temperatures (below 32°F / 0°C). If your scanner operates in freezers or outdoor winter conditions, test runtime expectations and consider keeping spare charged AC4146-1904 units at ambient temperature before field deployment.

The Socket Mobile AC4146-1904 AA NiMH battery is a straightforward consumable choice for field-deployed SocketScan fleets. If you're running 20+ handheld barcode scanners across warehouse or retail locations, switching from single-use alkaline to rechargeable NiMH makes hard financial sense—you'll recover the battery cost differential within 3–4 months and sustain savings thereafter. The real decision point is verifying scanner model compatibility; older SocketScan generations may not deliver optimal runtime on 1.2V NiMH nominal voltage.
Technical Highlights:
- Voltage Stability: NiMH delivers consistent 1.2V throughout discharge, vs. alkaline's gradual sag from 1.5V to 0.9V. Your scanner's 1D/2D scan engine maintains steady performance until the AC4146-1904 approaches exhaustion, reducing scan-quality variance during a shift.
- Cost Amortization: At ~60–70% per-cycle cost reduction vs. disposable batteries, a 50-unit scanner fleet eliminates roughly $3,000–$4,500 annual battery expense. Budget accordingly for external AA chargers if your scanner cradle doesn't support NiMH top-up directly.
- Self-Discharge Profile: Modern NiMH formulations hold 80%+ charge for 2–3 weeks. For intermittent-use scanners (checkout kiosks, seasonal peaks), you won't need to pre-charge daily—a maintenance simplification.
Deployment Considerations:
- Firmware compatibility is not guaranteed on legacy SocketScan models; test the AC4146-1904 in a pilot device before rolling out across a large fleet. Some scanner generations require alkaline-only operation.
- Cold-environment runtime drops significantly below 32°F. If your warehouse or outdoor asset-tracking operation runs in freezers or winter conditions, pre-test expected battery life and maintain heated spares at scanning stations.
Deploy the AC4146-1904 in warm-climate, multi-shift warehouse and retail scanning operations where scanner density is high enough to justify charger infrastructure. Skip this battery for occasional-use or freezer-based scanning without a separate warm-storage and charging strategy.
