Rechargeable Battery Panasonic HHR380A-LF NiMH 1.2V 3800mAh – Sub-C Size

Panasonic HHR380A-LF is a NiMH rechargeable Sub-C battery with a nominal voltage of 1.2V and a rated capacity of 3800mAh. The cell is designed for repeated charging cycles and delivers sustained power for high-drain applications. Built to fit equipment that accepts Sub-C cells, this battery offers stable output and reduced self-discharge compared with standard NiMH cells, making it suitable where predictable runtime and reliability are required.

Advantages

The battery provides a relatively high capacity for Sub-C format NiMH chemistry, enabling longer operating time between charges. Its chemistry supports numerous charge/discharge cycles and maintains a consistent voltage under load. Low self-discharge characteristics help preserve charge during storage and intermittent use. The cell is compatible with chargers and equipment designed for NiMH Sub-C batteries, simplifying integration into existing tool packs and battery holders.

Suitable for

• Cordless power tools and drills
• Hobby and RC devices with Sub-C battery compartments
• Portable industrial equipment and handheld instruments
• Battery packs assembled from Sub-C cells for custom solutions
• Backup power for sensors and remote monitoring devices

Key specifications

• Chemistry: Nickel–metal hydride (NiMH)
• Cell size: Sub-C
• Nominal voltage: 1.2 V
• Rated capacity: 3800 mAh
• Designed for repeated charge/discharge cycles
• Low self-discharge compared with standard NiMH cells

How to use

Install the battery into devices that accept Sub-C NiMH cells, observing correct polarity. Use a charger compatible with NiMH chemistry and Sub-C cell dimensions; follow the charger manufacturer’s instructions for recommended charge rates and termination methods. Allow the battery to cool to ambient temperature before charging if it has been used heavily, and avoid charging in extremely hot or cold conditions. For storage, keep the battery in a cool, dry place and recharge periodically to maintain capacity.

Usage recommendations

For longest service life, charge with a smart charger that supports NiMH cells and provides delta-V or temperature-based termination. Avoid deep discharge where possible, and balance charge/discharge cycles according to device requirements. If assembling battery packs, ensure cells are of matching capacity and state of charge to prevent imbalance.
