Rechargeable Mono D Battery Voltcraft VC-12714030 NiMH 11000 mAh 1.2 V

Voltcraft VC-12714030 is a rechargeable NiMH Mono D (D/HR20) battery offering a nominal voltage of 1.2 V and a rated capacity of 11,000 mAh. Engineered for devices that demand sustained current over long periods, this battery provides an alternative to single-use D cells by delivering many charge/discharge cycles and lowering ongoing battery costs and waste. The chemistry and capacity make it suitable where stable voltage and long runtime are important.

Advantages

This rechargeable D-size NiMH battery combines high capacity with the ability to endure repeated charging cycles, resulting in extended operating time for high-drain and continuous-use devices. Its chemistry maintains reliable voltage under load, improving performance in torches, radios and similar equipment. Replacing disposable cells with this rechargeable option reduces the frequency of replacements and the environmental impact associated with single-use batteries.

Suitable for

• High-power flashlights and work lights
• Portable radios and communication devices
• Camping lamps and outdoor lighting
• Hobby motors, RC equipment and powered toys
• Emergency kits and long-duration applications

Key specifications

• Battery chemistry: Nickel–metal hydride (NiMH)
• Cell size: Mono D / HR20
• Nominal voltage: 1.2 V
• Rated capacity: 11,000 mAh
• Rechargeable: yes, multiple charge/discharge cycles

How to use

Install the battery into compatible devices following the device polarity markings. Charge the battery with a charger compatible with NiMH cells and D-size format; follow the charger manufacturer’s instructions regarding charge current and duration. Allow the battery to cool to ambient temperature before charging if it has been in heavy use, and store charged batteries in a cool, dry place when not in use.

Usage recommendations

For longest service life, use a smart charger with temperature or delta-V termination suited for NiMH chemistry and avoid prolonged storage at full charge in high temperature environments. Cycle the battery occasionally if stored for extended periods to maintain capacity. Do not mix this rechargeable battery with disposable cells or with batteries of different capacities in the same device.
