9V Rechargeable Lithium Battery Voltcraft VC-9V-Li 1200mAh

Rechargeable 9V lithium battery Voltcraft VC-9V-Li 1200mAh provides a compact, high-capacity power source designed for replacing single-use 9V cells in a variety of portable devices. The cell delivers a stable nominal voltage suitable for electronics such as smoke detectors, multimeters, wireless microphones and other handheld instruments. Its rechargeable chemistry supports numerous charge cycles, lowering long-term operating costs and reducing disposable-battery waste.

Advantages

The Voltcraft 9V lithium battery offers a higher energy density and longer service life per charge compared with many traditional alkaline 9V cells. It maintains consistent output voltage under typical load conditions and recharges quickly on compatible chargers. Lightweight construction and a compact 9V form factor make it a direct replacement for standard battery compartments, and the rechargeable nature provides predictable runtime and reduced total cost of ownership over repeated use.

Suitable for

• Smoke and carbon monoxide detectors requiring periodic battery replacement
• Digital multimeters and portable test instruments
• Wireless microphones and audio transmitters
• Toys, remote controls and small household electronics using 9V cells
• Maintenance kits and field service toolkits

Key specifications

• Nominal voltage: 9 V compatible with devices that accept standard 9V cells
• Capacity: 1200 mAh (rechargeable lithium chemistry)
• Chemistry: rechargeable lithium cell optimized for high energy density
• Form factor: rectangular 9V-size cell for direct replacement of disposable 9V batteries
• Suitable operating conditions: indoor consumer electronics and portable instruments

How to use

Install the Voltcraft 9V lithium battery into the device’s battery compartment observing correct polarity. Charge the battery before first use and recharge as needed using a compatible charger designed for rechargeable 9V lithium cells. For best results, follow the charger manufacturer’s instructions and avoid leaving the battery at full charge for extended periods if the device will be unused for a long time. Dispose of or recycle the battery according to local regulations at end of service life.

Usage recommendations

Use a charger that supports rechargeable lithium 9V cells and includes appropriate charge control (constant-current/constant-voltage or dedicated battery pack management). Avoid exposure to extreme temperatures and mechanical damage. For devices with critical safety functions (for example smoke detectors), test the device regularly after installing the rechargeable battery to verify proper operation and replace or recharge the cell following the device manufacturer’s maintenance schedule.
