Rechargeable NiMH Battery Panasonic HHR-210AAB3B-1Z, 1.2V 2000mAh, Sub-C Size

Panasonic HHR-210AAB3B-1Z is a rechargeable NiMH battery with a nominal voltage of 1.2V and a rated capacity of 2000mAh in Sub-C size. The cell is intended for devices that require a medium-capacity, replaceable rechargeable battery. It supports multiple charge/discharge cycles and is compatible with standard NiMH chargers designed for Sub-C cells. The chemistry and construction provide stable voltage under moderate loads and predictable discharge characteristics suitable for a range of consumer and professional applications.

Advantages

This Sub-C NiMH battery delivers a balance of energy capacity and size, enabling extended runtime compared with smaller cells while remaining compact enough for many cordless devices. Rechargeability reduces the need for disposable batteries and lowers operational cost over time. The NiMH chemistry offers good tolerance to repeated cycling and consistent performance across typical operating temperatures. Compatibility with common NiMH chargers simplifies replacement and integration into existing equipment.

Suitable for

• Cordless power tools with Sub-C battery compartments
• Hobby and remote-control models requiring Sub-C cells
• Medical devices and instruments using rechargeable NiMH Sub-C batteries
• Backup power packs and battery holders for electronics
• Portable equipment where 1.2V nominal voltage and medium capacity are appropriate

Key specifications

• Cell type: Nickel-Metal Hydride (NiMH)
• Nominal voltage: 1.2 V
• Rated capacity: 2000 mAh
• Size/form factor: Sub-C
• Rechargeable: yes, multiple charge/discharge cycles

How to use

Install the Sub-C NiMH cell into the device or battery pack following the manufacturer’s polarity markings and mechanical retention features. Charge the battery using a charger specified for NiMH cells and appropriate for Sub-C size; follow the charger instructions regarding charge rate and end-of-charge detection. Allow the battery to cool after charging before placing it into continuous heavy-load use. Avoid deep discharge beyond device recommendations to maximize cycle life.

Recommendations

For best long-term performance, use a charger with temperature or delta-V cutoff designed for NiMH chemistry, store the battery in a cool, dry place when not in use, and avoid leaving the cell in a discharged state for extended periods. Periodic controlled cycling can help maintain capacity if the battery is stored for long periods.
