VARTA 4922 9V Alkaline Battery – Reliable Power for Critical Devices

Product: Alkaline Battery (9V Block)
Manufacturer: VARTA (Germany)

When it comes to devices that must perform flawlessly – such as smoke detectors or professional measuring tools – cheap batteries are not an option. The VARTA 4922 (6LR61) is one of the most popular choices on the market, valued for its stability and longevity.

1. Power and Long Service Life

This 9V alkaline cell is designed for devices requiring constant and long-term energy. Compared to cheaper zinc-carbon cells, VARTA alkaline technology ensures:

• Higher Capacity: The 200 mAh capacity allows devices to operate significantly longer, which is especially important for rarely maintained smoke sensors.
• Stable Voltage: A stable 9V output is maintained throughout its lifespan, ensuring the precision of measuring instruments.
• Discharge Resistance: Perfect for devices that spend most of their time in "standby" mode.

2. Universal Application and Standards

The VARTA 4922, also known as 6LR61 or 9V block, features standard dimensions (26.5 x 15.7 x 48.5 mm), making it suitable for all devices requiring a 9V battery. This element is most commonly used in:

• Security Systems: Smoke and carbon monoxide detectors.
• Musical Instruments: Guitar effect pedals, active pickups.
• Measuring Equipment: Multimeters, laser distance meters.
• Toys: Remote control units.

3. German Quality and Safety

VARTA is a leader in battery manufacturing, so the 4922 model features a reinforced casing that prevents electrolyte leakage. This is critical for expensive electronic equipment where repairs can cost ten times more than the battery itself. This power source is ready to operate even in fluctuating temperature conditions.
