Voltcraft HR03 rechargeable NiMH AAA (Micro) batteries provide 1100 mAh nominal capacity and 1.2 V nominal voltage in a compact AAA format. Supplied as a 4-pack, these cells are intended for repeated charging and discharging cycles and are compatible with a wide range of consumer electronics that require AAA batteries. The rechargeable design reduces single-use battery waste and lowers long-term operating costs for devices used frequently in home and office environments.
Advantages
These Voltcraft HR03 NiMH batteries combine a standard AAA size with moderate capacity to balance runtime and charge time. The cells offer stable voltage suitable for low- to medium-drain devices, are designed for multiple recharge cycles, and are sold in a convenient 4-pack for immediate replacement or rotation. The rechargeable chemistry eliminates the need for constant disposal of single-use batteries and supports more sustainable usage patterns.
Suitable for
- TV and media remote controls
- Wireless computer mice and keyboards
- Clocks, thermometers and small household sensors
- Small toys and handheld electronic games
- LED torches, night lights and decorative LED strings
When it may not be suitable
These AAA NiMH batteries are intended for low- to medium-drain devices; they may deliver shorter runtimes than high-capacity or specialized rechargeable cells in continuous high-drain applications such as high-performance flashlights, digital cameras, or some power-hungry toys. Also, devices requiring a different nominal voltage chemistry (for example lithium-based single-use cells) are not compatible without verifying device requirements.
Key specifications
- Cell chemistry: Nickel–metal hydride (NiMH)
- Size: AAA (Micro)
- Nominal voltage: 1.2 V
- Rated capacity: 1100 mAh
- Pack quantity: 4 cells
- Intended use: Rechargeable for repeated charge/discharge cycles
How to use
Install the AAA cells into the device following the polarity markings. Use a compatible NiMH battery charger designed for AAA cells and follow the charger manufacturer's instructions for charge current and duration. Allow batteries to cool after charging before inserting them into devices. For best performance, charge batteries before first use and recharge when device performance declines; avoid deep discharge where possible to extend cycle life.
What to consider before purchase
- Confirm device compatibility with 1.2 V NiMH AAA cells
- Ensure you have an appropriate charger for NiMH AAA batteries
- Consider whether higher-capacity AAA cells are needed for high-drain applications
- Note that actual runtime depends on device power draw and usage patterns
Usage recommendations
For balanced performance and longevity, store batteries at moderate temperature, avoid prolonged storage in fully discharged state, and cycle them periodically if stored long-term. Use matched cells from the same pack when multiple batteries are required in a device to ensure uniform performance.
