FAQs about the Varta V321 watch battery

What does the designation SR616SW mean?

The international IEC designation provides information about the battery. "S" stands for silver oxide, "R" for the round shape, "616" for the dimensions (6.8 mm x 1.65 mm) and the "SW" at the end indicates a "Low Drain" version. This is specially optimized for devices with low and constant current consumption, such as wristwatches.

Is this battery compatible with the designation SR65SW?

The Varta 321 corresponds to the internationally standardized IEC designation SR616SW. The designation SR65SW is not standardized and could lead to confusion. If your old battery says 321, this is the correct and suitable replacement.

For which watches is this battery type suitable?

The V321 is typically used in very small, flat wristwatches. Due to its small size, it is a popular choice for elegant and delicate ladies' watches with a particularly small movement.

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 or the municipal recycling centres to ensure environmentally friendly disposal.
