Precision energy for ultra-flat watches

The Varta V335 was specially designed for use in analogue and digital quartz watches with particularly small and flat movements. Its cell chemistry is optimised for a low, constant current consumption, which is characteristic of these types of watches. Its extremely flat dimensions make it the perfect choice for designer watches and other delicate timepieces.

Superior silver oxide technology

Compared to conventional alkaline batteries, the silver oxide technology of the V335 offers decisive advantages. The voltage remains stable over almost the entire service life of the battery, ensuring the precision of the device. The high energy density allows a long runtime in a very small form factor. Thanks to the minimal self-discharge, the battery is also extremely long-lasting in storage.

Efficiency and safety for your movement

Varta watch batteries undergo stringent quality controls to ensure consistently high performance and maximum safety. The high-quality manufacturing and sealing of the V335 cell provide reliable protection against leakage, thus preserving the sensitive movement from damage. Rely on tested quality for your valuable devices.

FAQs about the Varta V335 watch battery

What does the designation SR512SW mean?

The international IEC designation provides information about the battery. "S" stands for silver oxide, "R" for the round design, "512" for the dimensions (5.8 mm x 1.25 mm) and the "SW" at the end identifies a "low drain" version. This is specially optimised for devices with low and constant current consumption, such as wristwatches.

For which watches is this battery type particularly suitable?

The V335 is typically used in very small and particularly flat wristwatches. Due to its low height, it is a popular choice for elegant and delicate watch models where every millimetre counts.

Can I use a different battery instead of this one?

Because of its very specific and flat dimensions, replacement with another type of battery is generally not possible. It is important to use exactly the type specified by the watch manufacturer.

How should this watch battery be disposed of?

Watch batteries must not be disposed of in household waste. Please take the empty battery to the designated collection points in shops or municipal recycling centres for environmentally friendly disposal.
