## Long description

Varta V393 is a single-use button/coin cell battery that uses silver‑oxide chemistry to provide a stable nominal voltage of 1.55 V in a compact package. With dimensions of 7.9 mm in diameter and 5.4 mm in height, this cell is designed for small electronic devices that demand reliable, consistent power output over their service life. The silver‑oxide chemistry delivers good performance under low-drain constant loads and maintains voltage stability compared with alkaline alternatives.
Advantages
The Varta V393 offers stable voltage delivery throughout most of its discharge cycle, compact size for space-constrained designs, and compatibility with devices that require small, high-energy-density cells. Silver‑oxide construction reduces self-discharge and provides predictable end-of-life behavior, which is important for timekeeping and precision electronics.
Suitable for
 Wristwatches and timepieces
 Calculators and small portable electronics
 Key fobs and remote controls
 Medical devices such as glucose meters and hearing devices (where specified by manufacturer)
 Small sensors and measuring instruments

How to use
Install the Varta V393 cell in the device following the manufacturer’s polarity markings, ensuring the correct orientation of the positive and negative terminals. Avoid forcing the cell into a compartment; it should fit snugly without excessive pressure. Do not attempt to recharge the cell. Replace the cell when device performance or displayed indicators show reduced power. Dispose of used cells in accordance with local battery recycling and disposal regulations.
Usage recommendations
Store unused cells in a cool, dry place and avoid exposure to high temperatures or humidity. When replacing batteries in precision devices such as watches or medical equipment, use identical cell type and chemistry to ensure correct operation and to maintain accuracy.
