Oplaadbare NiMH-batterij Panasonic HHR450A-LF 1,2 V 4500 mAh (Sub-C)

Panasonic HHR450A-LF is a rechargeable NiMH Sub-C battery with a nominal voltage of 1.2V and a rated capacity of 4500mAh. Designed for applications that require extended runtime and reliable energy delivery, this cell is commonly used in power tool battery packs, portable equipment, and other high-drain devices. The chemistry provides stable discharge characteristics and supports multiple charge/discharge cycles, making it suitable for replacement cells and OEM battery assemblies.

Advantages

The battery delivers a high usable capacity of 4500mAh at 1.2V nominal voltage, enabling longer operation between charges compared with lower-capacity NiMH cells. Its Sub-C cylindrical format supports straightforward integration into multi-cell packs and many standard holders. The NiMH chemistry offers relatively low self-discharge and consistent voltage under load, and the cell is designed for repeated recharge cycles to reduce the need for frequent replacements.

Suitable for

• Power tool battery packs and cordless tools
• Portable and handheld equipment with high current draw
• Custom battery pack assemblies and OEM replacements
• Battery holders and hobby applications requiring Sub-C cells

Key specifications

• Cell type: Nickel–Metal Hydride (NiMH)
• Nominal voltage: 1.2 V
• Rated capacity: 4500 mAh
• Form factor: Sub-C cylindrical cell
• Typical use: high-drain devices and multi-cell packs

How to use

Charge the battery using a charger designed for NiMH cells and observe the charger's recommended charging current and termination method. Install cells in the correct orientation when assembling multi-cell packs or placing them into holders. Allow the battery to cool to ambient temperature before charging if it has been under heavy load, and avoid deep discharge below the device manufacturer's recommended cutoff voltage to prolong cycle life.

Recommendations

For optimal longevity, use a smart charger with delta-V or temperature-based termination, avoid prolonged storage at high temperatures, and store the cells in a cool, dry place when not in use. Replace cells in multi-cell packs in matched sets to maintain balanced performance.
