FAQs about the Varta V381 watch battery

What does the designation SR1120SW mean?

The international IEC designation provides information about the battery. "S" stands for silver oxide, "R" for the round design, "1120" for the dimensions (11.6 mm x 2.1 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.

Is this battery compatible with the designation SR55SW?

The Varta 381 corresponds to the internationally standardised IEC designation SR1120SW. The designation SR55SW is not standardised. Please check the number on your old battery. If it says 381 or SR1120SW, this is the correct and suitable replacement.

Can I replace an LR1120 (LR55) alkaline battery with this V381?

Yes, this is possible in almost all cases and represents a significant upgrade. The V381 (SR1120SW) 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 V381 is strongly recommended for high-quality 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 shops or municipal recycling centres to ensure environmentally friendly recycling.
