Varta 1.55V 30mAh Watch Battery, Type V329

Varta 1.55 V 30 mAh Watch Battery (Type V329)

The Varta V329 is a premium silver‑oxide button cell designed specifically for timepieces that require a reliable, long‑lasting power source. With its compact dimensions and high energy density, this battery delivers consistent performance in a wide range of watch models.

Key Technical Specifications

• Nominal Voltage: 1.55 V – the standard voltage for most quartz watches.
• Capacity: 36 mAh (30 mAh nominal) – providing ample energy to keep your watch running smoothly for months.
• Type: Silver‑oxide (AgO/Zn) button cell – known for its stable voltage output and long shelf life.
• Dimensions: 7.9 mm × 3.1 mm – a perfect fit for the majority of V329-compatible watch cases.
• Reference Code: 00329‑101‑111 – a unique identifier used by manufacturers and distributors worldwide.

Design & Construction

The V329 features a robust silver‑oxide cathode that delivers a steady voltage over its entire discharge cycle. The zinc anode provides the necessary reduction reaction, ensuring that the cell maintains its 1.55 V output until it reaches the end of life. The sealed construction prevents leakage and protects the internal chemistry from environmental factors such as humidity and temperature fluctuations.

Performance Characteristics

• Stable Voltage: Unlike alkaline cells, silver‑oxide batteries maintain a consistent voltage until depletion, which is critical for accurate timekeeping.
• Long Shelf Life: The V329 can be stored for several years (typically up to 10 years) without significant loss of capacity, making it ideal for watches that are not worn daily.
• Low Self‑Discharge Rate: The cell’s chemistry minimizes self‑discharge, preserving charge even when the watch is inactive.

Compatibility & Applications

The V329 is engineered for a wide range of quartz watches, including:

• Analog and digital timepieces with standard button cell compartments.
• Luxury wristwatches that demand high reliability.
• Smartwatches and hybrid devices that use a 1.55 V power source for basic functions.

Because of its standardized size and voltage, the V329 can also be used in other small electronic devices such as key fobs, remote controls, and medical monitoring instruments that require a compact, long‑lasting battery.

Installation Guide

1. Open the watch case using the appropriate tool (usually a small screwdriver or coin).
2. Remove the old battery carefully to avoid damaging the contacts.
3. Insert the new V329 with the positive side facing up, ensuring it sits snugly against the contact pads.
4. Close the case securely and test the watch for proper operation.

Environmental & Safety Considerations

The silver‑oxide chemistry of the V329 is non‑toxic and does not contain heavy metals such as lead or mercury. However, it should still be disposed of in accordance with local regulations for electronic waste to prevent environmental contamination.

Quality Assurance & Brand Heritage

Varta has a long-standing reputation for producing high‑quality batteries that meet stringent industry standards. The V329 undergoes rigorous testing, including:

• Voltage stability tests across temperature ranges.
• Capacity verification against the specified 36 mAh rating.
• Leakage and safety assessments to ensure user protection.

This commitment to quality guarantees that each V329 battery delivers dependable performance from the moment it is installed.

Conclusion

The Varta V329 1.55 V 30 mAh Watch Battery stands out as a reliable, long‑lasting power source for modern timepieces. Its silver‑oxide chemistry, precise voltage output, and robust construction make it an excellent choice for anyone seeking to maintain accurate timekeeping without frequent battery replacements.

Whether you are a watch enthusiast, a repair technician, or simply looking for a dependable backup power solution, the V329 offers the performance and durability that your device deserves.
