HFD-A04 Internal Battery for Load Cells — 70 h Runtime | KERN

The HFD-A04 is an internal rechargeable battery designed for integration with load transmitters and industrial scales, delivering extended operation for unattended weighing applications.

• 70 h continuous operating time
• 12 h recharge cycle
• Compact 0.2 kg design
• For integration with load cells

Reliable operation for uninterrupted weighing processes

Built for industrial metrology, this internal battery provides up to 70 h of operation, enabling prolonged measurement runs without frequent intervention. The long runtime, combined with a 12 h charging interval, reduces the frequency of planned maintenance and supports shift-based production. Such predictable endurance translates into tangible efficiency gains on the shop floor: weighing systems remain available for longer periods, thereby improving throughput and reducing indirect labour costs. The energy supply is suitable for applications where consistent power to weighing electronics and transmitters is essential.

Designed for seamless integration with load cells and transmitters

The unit is intended for connection to load cells and weighing transmitters where an internal power source is required. By supplying stable voltage over extended cycles, the module helps maintain weighing precision even during intermittent mains interruptions. In practice, this means measurement stability is preserved and recalibration intervals are minimised. The technology behind the battery supports common industry requirements for compact power solutions in scales accessories, allowing straightforward integration into existing weighing assemblies while maintaining the original performance characteristics of the instrument.

Compact, low-mass design for flexible installation

Weighing just 0.2 kg, the battery is compact enough for confined instrument housings and does not significantly affect the balance or mounting of sensitive measuring equipment. The lightweight construction simplifies retrofits and new installations alike, and the rechargeable nature of the unit reduces consumable replacements. Handling and storage are uncomplicated thanks to the small footprint, and predictable charge and discharge behaviour makes planning for maintenance cycles straightforward. Where space is limited or weight influences installation, this module provides a practical, space-saving power option.
