9V Li-Ion Block Battery Voltcraft VC-12714055 7.4V 500mAh

The 9V Li-Ion Block Battery Voltcraft VC-12714055 7.4V 500mAh is a rechargeable power cell designed as a direct replacement for single‑use 9V batteries in devices that accept a 7.4V lithium‑ion block. With a nominal voltage of 7.4 volts and a 500 mAh capacity, this compact battery offers consistent output for portable instruments, test equipment and small consumer electronics while reducing waste compared with disposable cells. It is intended for use with a compatible Li‑ion charger and requires standard safety precautions for lithium‑ion batteries.

Advantages

This rechargeable 9V Li‑Ion block provides stable voltage and low self‑discharge for reliable standby life. The higher energy density compared with alkaline or NiMH 9V cells allows a smaller form factor and repeated recharge cycles to lower operating costs. The battery is lightweight and compact, enabling installation in compact housings and handheld devices. Designed for reuse, it contributes to reduced environmental impact when used instead of single‑use batteries.

Suitable for

• Portable test instruments and multimeters that accept a 7.4V Li‑ion block
• Handheld smoke detectors, carbon monoxide alarms and safety sensors rated for 7.4V Li‑ion blocks
• Small electronic devices such as wireless microphones, guitar pedals and portable audio gear compatible with 7.4V Li‑ion blocks
• Battery replacement in educational equipment and lab devices that require a compact rechargeable 7.4V source

Key specifications

• Nominal voltage: 7.4 V
• Rated capacity: 500 mAh
• Chemistry: Lithium‑ion (Li‑ion)
• Form factor: 9V block style, compact rechargeable module
• Typical applications: portable instruments, small electronics, test equipment

How to use

Charge the battery only with a charger that supports 7.4V Li‑ion blocks and follow the charger manufacturer’s instructions. Insert the battery into the device following correct polarity and ensure secure contact with terminals. For initial use, fully charge the battery before operating the device. Avoid deep discharges when possible and recharge the battery after use or when device performance decreases. If storing the battery for an extended period, store it partially charged in a cool, dry place.

Usage recommendations

Do not expose the battery to high temperatures, water or mechanical shock. Do not attempt to open, puncture or modify the cell. Use only compatible chargers and avoid mixing with non‑rechargeable batteries or cells of different voltages. Dispose of the battery in accordance with local regulations for lithium‑ion batteries.
