Single-use battery Varta 4R25X 8500mAh (431) 6V

The Varta 4R25X 8500mAh (431) 6V is a single-use zinc chloride battery designed to deliver steady power for equipment requiring a 6 V supply. With a nominal capacity of 8500 mAh, this cylindrical cell is intended for devices where long, reliable discharge is needed and where rechargeable solutions are not suitable. The battery is CE certified and comes in a compact form factor with dimensions 67 mm × 67 mm × 115 mm, making it compatible with a range of medium-size portable devices and equipment.

Advantages

This Varta zinc chloride battery provides consistent voltage output over its service life and is manufactured to meet CE safety standards. Its high nominal capacity reduces the frequency of replacement in applications with moderate to low continuous drain. As a primary (single-use) cell, it requires no charging infrastructure and can be stored for extended periods when unused. The battery’s weight and standardized shape support straightforward installation in compatible compartments.

Suitable for

• Portable lighting and lanterns
• Measurement instruments and sensors
• Emergency and backup devices with 6 V requirement
• Outdoor equipment and camping appliances
• Industrial handheld devices

How to use

Install the battery into the device following the polarity markings and the manufacturer’s instructions for that device. Single-use batteries do not require charging; replace the cell when the device indicates low power or performance declines. Store unused batteries in a cool, dry place away from direct heat sources and metallic objects to avoid short circuits. Dispose of the battery according to local regulations for primary batteries and recycling programs where available.

Recommendations

For optimal performance, use the Varta 4R25X in devices with steady moderate drain rather than high-drain electronics. Avoid mixing old and new batteries or different chemistries in the same device. Follow device manufacturer guidelines for installation and observe local disposal and recycling rules to minimize environmental impact.
