VARTA V430 LONGLIFE 4R25X Light Disposable Battery

The VARTA V430 LONGLIFE 4R25X is a high‑performance, single‑use battery designed for continuous operation in security and lighting applications. With its robust zinc‑carbon chemistry, it delivers reliable power where longevity and dependability are paramount.

Key Technical Specifications

• Voltage: 6 V
• Capacity: 7 500 mAh (10 Ah equivalent)
• Dimensions: 97 mm height × 66 mm width × 66 mm depth
• Type: 4R25 block battery
• Technology: Zinc‑Carbon (Zinc Chloride)
• Application: Security devices, alarm systems, permanent light lamps, flashing lamps, and other continuous‑power lighting solutions.

Design & Construction

The battery features a robust plastic casing that protects the internal zinc‑carbon cell from mechanical shock and environmental factors. A spring contact mechanism ensures secure electrical connection in devices with recessed terminals. The sealed design prevents electrolyte leakage, making it suitable for outdoor or harsh environments.

Performance Characteristics

The Zinc‑Carbon chemistry offers a stable voltage output of 6 V over the entire discharge cycle. This stability is critical in alarm systems and continuous lighting where sudden voltage drops can trigger false alarms or dim lights.

• High Capacity: 7 500 mAh guarantees extended operation, reducing maintenance frequency for security installations.
• Low Self‑Discharge: The sealed construction minimizes self‑discharge, allowing batteries to be stored for long periods without significant loss of charge.
• Consistent Power Delivery: Maintains a near‑constant voltage until the end of life, ensuring reliable performance in critical applications.

Ideal Applications

The VARTA V430 LONGLIFE is engineered for scenarios where uninterrupted power is essential. Typical use cases include:

• Security Systems: Alarm panels, motion detectors, and surveillance cameras that require continuous operation.
• Permanent Lighting: Outdoor floodlights, street lamps, and safety illumination on construction sites.
• Flashing Lamps: Traffic signal backup lights, emergency vehicle indicators, and portable lanterns used in field operations.
• Industrial Equipment: Backup power for control panels, monitoring devices, and other critical instrumentation.

Installation & Handling Guidelines

When installing the V430 LONGLIFE, ensure that:

• The battery is inserted with correct polarity; reverse insertion can damage the device.
• Device terminals are clean and free of corrosion to maintain a solid electrical connection.
• The battery is stored in a dry environment at temperatures between 0 °C and 40 °C for optimal longevity.

Compatibility Overview

The V430 LONGLIFE is compatible with any device that accepts a standard 4R25 block battery. Its dimensions (97 mm × 66 mm × 66 mm) and voltage match the industry standard for security and lighting applications, making it a drop‑in replacement for older zinc‑carbon batteries.

Environmental Considerations

As a sealed zinc‑carbon battery, the V430 LONGLIFE is designed to minimize environmental impact. The absence of hazardous heavy metals such as lead or cadmium simplifies disposal and recycling processes. Users should still follow local regulations for battery disposal.

Summary

The VARTA V430 LONGLIFE 4R25X delivers dependable, long‑lasting power in a compact form factor. Its high capacity, stable voltage output, and robust construction make it the preferred choice for security systems, permanent lighting, and any application where continuous operation is non‑negotiable.
