FAQs about the Varta V329 watch battery

What does the designation SR731SW mean?

The international IEC designation provides information about the battery. "S" stands for silver oxide, "R" for the round design, "731" for the dimensions (7.9 mm x 3.1 mm) and the "SW" at the end indicates a "low drain" version. This is specially optimised for devices with low and constant power consumption, such as wristwatches.

Can I replace an LR731 alkaline battery with this V329?

Yes, this is possible in almost all cases and represents a significant upgrade. The V329 (SR731SW) offers a longer service life and a more stable voltage, which improves the accuracy of your watch. The use of a silver oxide battery such as the V329 is strongly recommended for high-quality watches.

For which watches is this battery type suitable?

The V329 is typically used in flat wristwatches, which require slightly more energy than the very small, delicate models. It is a common size for many ladies' and men's watches.

How should this watch battery be disposed of?

Watch batteries must not be disposed of with household waste. Please take the empty battery to the designated collection points in retail outlets or municipal recycling centres to ensure environmentally friendly recycling.
