Uninterrupted Power for Industrial Data Collection: 7.4V Battery Enables All-Day Rugged Tablet Operation

September 25, 2025
Latest company case about Uninterrupted Power for Industrial Data Collection: 7.4V Battery Enables All-Day Rugged Tablet Operation
Background & Challenge:

Our customer needed a power source for their new "FieldMaster T50" rugged tablet, used by warehouse and logistics personnel for extended shifts. The device powers a bright display, barcode scanner, and data transmission module. The challenge was twofold: first, the battery needed a slim, rectangular form factor to fit the tablet's handle. Second, it had to deliver stable voltage under pulsed loads (from the scanner and radio) and maintain operation for a full 8-10 hour shift, withstanding occasional drops and vibrations.

Our Solution:

We delivered 7.4V 1450mAh Li-Polymer Battery BAKTH-474948-2S-2J that met both the spatial and performance demands.

  • Form-Fit Design: The battery was engineered to perfectly occupy the available space within the tablet's handle, maximizing capacity without altering the device's ergonomic design.

  • High Voltage Efficiency: The 7.4V platform reduced current draw compared to lower-voltage batteries for the same power output, leading to less internal heat generation and higher overall efficiency for the device's power regulation system.

  • Pulse Discharge Capability: Specially formulated cells ensured minimal voltage sag during the high-current pulses required by the barcode scanner, preventing system resets or scan errors.

  • Enhanced Safety & Durability: The battery pack included a robust Battery Management System (BMS) with protection against impacts and vibrations, crucial for an industrial-grade tool.

Key Specifications Highlighted:

  • Nominal Voltage: 7.4V

  • Capacity: 1450mAh

  • Dimensions: 53.5*51*10mm

  • Max. Discharge Current: 1C handle pulse loads.

  • Cycle Life: ≥300 cycles (ensuring long-term device usability).

Results & Feedback:

Achieved its goal of all-day battery life, with users reporting consistent performance until the end of their shifts. The reliability of the power system significantly reduced support calls related to unexpected shutdowns. DataLogic Project Manager noted: "The stability of this 7.4V battery under pulsed loads was critical. It's not just about capacity; it's about delivering power predictably in a real-world industrial setting. This partnership ensured our device's core promise of reliability."
