Rechargeable 9V NiMH Battery Voltcraft VC-12714065 8.4V 270mAh

Rechargeable 9V NiMH Battery Voltcraft VC-12714065 8.4V 270mAh is a rechargeable replacement for single-use 9V cells. With a nominal voltage of 8.4V and a usable capacity of 270mAh, this NiMH battery is intended for devices that require compact block-type power sources. The battery provides consistent output suitable for household and portable electronics, reducing waste and offering lower operating cost over repeated charge cycles when used with a compatible NiMH charger.

Advantages

The Voltcraft 8.4V NiMH cell delivers stable voltage under typical loads and can be recharged many times, which lowers long-term cost compared with disposable batteries. Its chemistry supports relatively fast charging and better performance at moderate discharge rates compared to older rechargeable technologies. The compact block format fits standard 9V battery compartments used in smoke detectors, multimeters, wireless microphones and many small electronic devices.

Suitable for

• Smoke detectors and alarm systems
• Portable multimeters and test equipment
• Wireless microphones and small audio transmitters
• Toys, remote controls and handheld electronics
• Backup power for low-drain devices

Key specifications

• Chemistry: Nickel-Metal Hydride (NiMH)
• Nominal voltage: 8.4 V
• Capacity: 270 mAh
• Cell format: 9V block-style rechargeable battery
• Rechargeable: yes, compatible with NiMH chargers
• Typical applications: low to moderate drain portable devices

How to use

Install the battery into the device’s 9V compartment observing polarity. Use a charger designed for NiMH block batteries and follow the charger manufacturer’s instructions for charging current and charge termination. Allow the battery to reach full charge before first use for optimal capacity, and avoid deep discharge cycles when possible to prolong service life. Replace the battery in devices where reliable backup power is critical according to the device manufacturer’s maintenance schedule.

Usage recommendations

Store the battery in a cool, dry place and avoid prolonged exposure to high temperatures. Use a charger with appropriate NiMH charge control (delta-V, temperature or timer-based) and avoid charging at currents higher than recommended by the charger manufacturer. For devices that sit idle for long periods, periodically charge the battery to maintain capacity and prevent self-discharge from rendering the device inoperative.
