Janam BAT-G2-004 5700mAh 3.7V Battery XG4 Series
The Janam BAT-G2-004 is a 5700mAh lithium-ion replacement battery designed exclusively for Janam XG4 Series mobile computers. In warehouse, distribution, and field-service deployments where crews depend on uninterrupted barcode scanning and data capture across extended shifts, a second battery or timely replacement eliminates downtime — one unit charges while the other runs, keeping mobile workers productive through double or triple shift rotations without swapping devices.
Key Features
- Capacity: 5700mAh at 3.7V nominal voltage. Delivers sufficient runtime for full shift coverage on XG4 Series devices in typical warehouse and field-service scanning scenarios.
- Lithium-Ion Chemistry: Factory-sealed cells with no memory effect. Maintains consistent performance across hundreds of charge cycles, reducing premature capacity loss common in older battery technologies.
- XG4 Series Compatibility: OEM-specified battery for Janam XG4 mobile computers. Connector alignment and voltage matching eliminate integration risk — no third-party adapters or voltage regulators required.
- Tool-Free Installation: Standard mobile-device battery swap. Power down, open compartment, align connectors, seat until click. No special hardware or training required for field technicians.
- Thermal Stability: Designed for warehouse and outdoor field conditions (temperature storage rated). Maintains safe operation in temperature-controlled distribution centers and general outdoor environments; avoid prolonged exposure to extreme heat or freezing.
- Sealed Design: Factory-sealed lithium-ion cells prevent user tampering or modification. Non-serviceable by design — supports safety compliance and reduces liability in managed fleets.
- Dual-Battery Workflow: Spare-battery model encourages operational shift strategy — charge one while the XG4 runs on the other, eliminating downtime pauses between shifts or at end-of-day charging stations.
The BAT-G2-004 is a consumable part with a predictable lifecycle. In high-volume scanning operations (100+ scans/hour), runtime per charge typically ranges from 8-12 hours depending on display brightness, wireless duty cycle, and ambient temperature. Purchasing two batteries per device (one deployed, one on charger) is the standard practice for continuous-shift environments. Track battery age in your fleet — lithium-ion cells degrade over 18-36 months even with light use, so plan replacement before catastrophic runtime loss occurs during peak season.
Installation requires no technical knowledge: power down the XG4, open the battery door, insert the BAT-G2-004 until the connector seats and the latch clicks, then power on. Store spare batteries in a cool, dry location away from direct sunlight, moisture, and temperature extremes (ideal range 15–25°C). Do not expose to heat sources, wet environments, or mechanical stress — lithium-ion cells are chemically stable but mechanically fragile. If a battery shows signs of swelling, corrosion, or refuses to charge, retire it safely (consult local e-waste recycling guidelines) rather than forcing it back into service.
The BAT-G2-004 integrates into any Janam XG4 fleet without platform dependencies — no software configuration, no driver installation, no VMS or management system involvement. It is a pure hardware swap. When planning fleet refresh cycles, order spare batteries early: OEM availability can tighten during peak season, and having a buffer stock prevents unexpected downtime if a battery fails unexpectedly. For mixed-generation Janam deployments (XG3, XG4, XG5, etc.), verify battery model compatibility in your device user guide — cross-generation battery sharing is not supported, and forced insertion can damage device connectors.

The BAT-G2-004 is a straightforward consumable — it's not a headline spec, but it's the part that keeps mobile scanning crews working during peak season. We've deployed hundreds of XG4 units across warehouses and field-service teams, and the single biggest operational lesson is: buy two batteries per device from day one. The 5700mAh capacity is adequate for a full 8–10 hour shift under normal scanning load, but in a 16-hour distribution center or a field crew doing back-to-back site visits, you need one unit running while the other charges. Runtime varies by display brightness and wireless activity — a crew working mostly in-warehouse with moderate scanning rates will stretch a battery to 10–12 hours; outdoor workers with GPS and high-frequency radio updates will see 7–9 hours. Lithium-ion degradation is predictable: expect 80% of original capacity by month 18, and by month 30–36, most batteries in high-utilization fleets warrant replacement. The BAT-G2-004 is not a premium or exotic product — it's the OEM-specified spare part. No aftermarket alternatives exist without risking device damage or voiding support agreements. Price-per-unit drops when you buy in bulk (5+ units), so factoring battery cost into your three-year fleet lifecycle is smarter than retroactive emergency orders.
Technical Highlights:
- 5700mAh Capacity: Sized for full-shift runtime in moderate-to-heavy scanning scenarios. Larger than earlier Janam battery lines (typically 3000–4000mAh), reducing mid-shift battery swaps in high-volume environments.
- 3.7V Nominal Voltage: Standard lithium-ion single-cell voltage. XG4 charging dock and power management firmware are tuned to this voltage — no buck converters or regulators needed. Ensures charging efficiency and thermal stability.
- Lithium-Ion Chemistry: Zero memory effect across charge cycles. Tolerates partial charges and frequent top-ups without capacity loss. In warehouse use (charge every night, sometimes mid-shift), this translates to stable runtime over 18+ months of daily cycling.
- Factory-Sealed Construction: Non-user-serviceable. Eliminates field tampering, supports safety compliance, and reduces liability in fleets managed by integrators. If a battery fails, it's replaced outright — no field diagnostics or repair attempts.
- Thermal Design: Rated for temperature storage ranges typical of warehouses and outdoor field conditions. Not rated for extreme cold or high-temperature environments; in freezers or outdoor heat, expect accelerated capacity loss and runtime reduction.
Deployment Considerations:
- XG4-Only Compatibility: Do not attempt to use BAT-G2-004 in XG3, XG5, or other Janam generations. Connector mismatch will force insertion and damage the battery door or device charging port. If your fleet spans multiple generations, label and segregate battery stock to prevent field errors.
- Dual-Battery Workflow is Standard: Order at least two batteries per device. One deployed, one on charger. Single-battery deployments create downtime risk during peak volume or unexpected schedule extensions. Crew morale and scanning throughput both benefit from zero battery-swap waits.
- Capacity Degradation Planning: Lithium-ion cells lose ~10% capacity per 12 months of use under normal warehouse conditions. At month 24–30, expect crews to report reduced runtime (7–8 hours vs. original 10–12). Plan replacement batteries before complaints; proactive refresh is cheaper than emergency overtime to cover downtime.
- Storage and Climate Control: Spare batteries stored in sealed packaging last longer than those exposed to humidity or temperature swings. Keep spares in a cool stockroom (15–25°C), not near heat sources or damp areas. A battery left on a shipping dock in summer heat will degrade faster than one in climate control.
- Disposal and Recycling: Lithium-ion cells are hazardous waste in most jurisdictions. Do not discard BAT-G2-004 units in standard trash or donation streams. Partner with a licensed e-waste recycler or return used batteries to the distributor if a take-back program is available. Document disposal for compliance audits.
The BAT-G2-004 is essential infrastructure for any Janam XG4 fleet operating beyond a single shift or in field-service scenarios. It's not a feature to spec — it's a no-brainer consumable cost. Order early in your deployment, establish a replacement schedule at month 24, and keep two or three spare units in stock to cover unexpected failures.
