FAQs about the Varta V344 watch battery

What does the designation SR1136SW mean?

The international IEC designation gives information about the battery. "S" stands for silver oxide, "R" for the round form factor, "1136" for the dimensions (11.6 mm x 3.6 mm) and the "SW" at the end marks a "low drain" version. This is specially optimised for devices with low and constant power consumption.

Is this battery compatible with the designation SR42SW?

The Varta 344 corresponds to the internationally standardised IEC designation SR1136SW. The designation SR42SW is not standardised and could lead to confusion. If the number 344 is on your old battery, this is the correct and suitable replacement.

Can I replace an LR1136 alkaline battery with this V344?

Yes, this is possible in almost all cases and is a clear upgrade. The V344 (SR1136SW) offers longer lifespan and a more stable voltage, which improves the accuracy of your watch. The use of a silver oxide battery such as the V344 is expressly recommended for high-quality watches.

How should this watch battery be disposed of?

Watch batteries may 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 responsible recycling.
