Janam BAT-P1-075 4100 mAh 3.8V Lithium-Ion Battery
The Janam BAT-P1-075 is a 4,100 mAh, 3.8V lithium-ion replacement battery designed for the Janam XM75 and XM75+ mobile computers. This is a field-serviceable power module — swap it in the field when the primary battery depletes or when your deployment requires extended runtime without returning the device for depot service. The XM75/XM75+ automatically recognize the battery on connection; no firmware updates or reconfiguration are needed.
Key Features
- Capacity & Voltage: 4,100 mAh at 3.8V. Delivers consistent runtime for a full shift of data capture, RFID inventory, or barcode scanning in warehouse and retail environments.
- Lithium-Ion Chemistry: Safe, proven chemistry with minimal self-discharge and stable discharge curves. No memory effect — partial charges do not degrade cycle life.
- XM75/XM75+ Native Compatibility: Direct mechanical fit — works exclusively with Janam XM75 and XM75+ handheld computers. Confirm your device SKU before purchasing.
- Field-Swap Installation: No tools, no firmware. Power off the device, open the rear/side battery compartment, slide the battery until it locks, and power on. Automatic recognition on dock cradle or AC charger.
- Lithium-Ion Safety & Compliance: RoHS and WEEE compliant. Meets transportation and handling standards for internal logistics networks and cross-border supply chains.
- Extended Runtime Option: Carry a second BAT-P1-075 to double your operational window in the field — useful for multi-shift warehouses or outdoor asset verification routes without mid-day charging stops.
The XM75 and XM75+ are rugged industrial handhelds built for high-throughput environments: warehouses, distribution centers, and retail back-of-house operations. Battery life is mission-critical. A single shift of intensive barcode scanning and RFID tagging can exhaust the original battery by mid-to-late shift, especially during peak inventory periods. The BAT-P1-075 is your field replacement option — no downtime waiting for a spare device to arrive.
Runtime performance depends on workload intensity: continuous RFID reads and wireless transmission drain faster than intermittent barcode scans with local buffering. In typical mixed-duty warehouse workflows (30% scanning, 40% movement/idle, 30% transmission), the 4,100 mAh capacity provides 8–10 hours of continuous operation at room temperature. Cold-storage environments (below 10°C) may see 15–20% runtime reduction. Plan battery rotation accordingly — deploy a three-battery rotation for multi-shift operations in sub-zero environments.
Charging is standard: dock the XM75/XM75+ in its cradle, or use the supplied AC adapter over the device's USB or proprietary connector. The battery charges alongside the device; no external charger is required. For fleet deployments, integrate BAT-P1-075 inventory into your spare-parts bin — typical guidance is one backup battery per two active devices, refreshed annually to account for cycle-wear. Lithium-ion batteries degrade gradually: expect 80–85% original capacity after 18–24 months of daily charging cycles.
Janam warrants this battery against manufacturing defects; RoHS and WEEE compliance certifications document environmental stewardship and safe decommissioning pathways when the battery reaches true end-of-life (typically 3–5 years). For fleet-wide battery management, track serial numbers and charge cycles via your inventory system — lithium cells lose capacity predictably, and proactive replacement before field failures improves uptime. See the BAT-P1-075 datasheet for detailed charge curves and thermal specifications.

We've deployed the Janam XM75/XM75+ across distribution centers and retail chains for two years — these devices are workhorses in high-throughput barcode and RFID environments. The BAT-P1-075 is the single most requested spare part from our customer base. Here's why: the original battery out-of-box is rated for 8–10 hours of mixed duty, but real-world peak-season inventory cycles (Black Friday stocktake, seasonal vendor audits) run 12–14 hours continuously with wireless transmission to backend systems. After four to six months of daily shifts, the original battery's effective capacity drops 10–15%, pushing usable runtime down to 6–7 hours. That forces either two-device rotation or mid-shift charging — operationally messy and expensive. The BAT-P1-075 solves this by giving you a hot-swap option: keep two batteries charged in your locker, swap them in 30 seconds, and run continuous operations without cradle time. For large deployments (50+ devices), we recommend a 1:3 battery-to-device ratio — three spares for every two active units — rotating them weekly so no single battery ages beyond 2 years.
Technical Highlights:
- 4,100 mAh Capacity & 3.8V Chemistry: Lithium-ion at this capacity/voltage is optimized for moderate-power handhelds. The XM75/XM75+ draw 0.5–1.0A during active scanning and transmission; the 4,100 mAh nominal capacity translates to 4–8 hours of continuous load before voltage sag forces the device to lower brightness or throttle RF transmission. Partial-duty cycles (intermittent scanning) easily extend this to 10–12 hours.
- Minimal Self-Discharge: Lithium-ion loses only 2–3% per month sitting in inventory. Unlike older NiMH batteries, you can stock BAT-P1-075 units for seasonal peak periods without pre-charging or capacity loss. A battery sitting for 6 months retains 85–90% of its charge.
- No Memory Effect: You can top-charge the battery from 50% without degrading cycle life. This is critical for operational flexibility — staff can dock devices opportunistically (during breaks, lunch) without waiting for a full discharge-recharge cycle. Contrast this with older Ni-Cd batteries where partial-cycle charging is a no-go.
- RoHS/WEEE Compliance: If you operate internationally (Canada, EU) or manage fleet decommissioning through certified e-waste vendors, these certifications are mandatory documentation. Standard batteries purchased from grey-market channels often lack compliance paperwork, creating liability and disposal cost surprises.
- Automatic Device Recognition: The XM75/XM75+ firmware detects battery health and capacity on connection. You don't recalibrate the device or manually update power profiles. The device automatically adjusts power-saving features based on remaining charge — critical for field crews who can't monitor battery percentage constantly.
Deployment Considerations:
- Confirm your XM75 or XM75+ firmware version before deployment — very early firmware (pre-2019) had intermittent battery-recognition issues in cold rooms. If you're using legacy devices, update firmware first or keep one original battery as a reference unit for diagnostics.
- In sub-zero storage environments (freezers at –18°C or below), lithium-ion capacity drops 20–30%. If your warehouse includes cold zones (frozen food, pharmaceutical storage), plan for shorter runtime and consider a thermal battery case for devices working in those areas. The battery itself will recover to full capacity when warmed; there's no permanent damage, just temporary performance loss.
- Battery disposal and recycling: lithium-ion is hazmat for air/sea transport and requires certified e-waste handling. If you're managing a large fleet refresh, factor in certified battery recycling costs — typically $1–2 per unit through registered programs like Call2Recycle or equivalent regional partners.
- Charging protocol: use the Janam dock cradle or OEM charger only. Non-standard chargers can deliver incorrect voltage and damage battery longevity. We've seen field incidents where staff used generic USB chargers and saw battery capacity drop from 4,100 to 2,500 mAh in 6 months.
- Storage life: if you're stocking BAT-P1-075 units for seasonal use, store at 40–50% state-of-charge and room temperature (15–25°C). Full-charge storage over 6+ months accelerates aging; empty storage risks over-discharge, which can render the battery non-recoverable.
The BAT-P1-075 is the right choice for any warehouse or retail operation deploying XM75/XM75+ devices on multi-shift, high-utilization schedules. If your devices are light-duty (4–6 hours daily) and you have unlimited cradle-charging downtime, the original battery may suffice. But in real-world peak-season environments, a second BAT-P1-075 per device is cost-justified within 6 months.
