SR1120W is the international IEC standard. Here, "S" stands for silver oxide, "R" for the round shape, "1120" for the dimensions (11.6 mm diameter and 2.1 mm height) and "W" for "High Drain". The number 391 is the specific type number from the manufacturer Varta.What is the difference between a "High Drain" and a "Low Drain" battery? The main difference is in the ability to supply current. "Low Drain" batteries (with the suffix SW, e.g. 392 / SR1120SW) are designed for devices with a very low and constant energy demand, such as simple analogue watches. "High Drain" batteries like the V391 are designed for devices that require a lot of energy for a short time, for example for dial illumination or an alarm tone.Can I use a High Drain battery in a watch intended for Low Drain batteries? Yes, this is technically possible. A High Drain battery (like the V391) will work perfectly in a simple analogue watch that actually requires a Low Drain cell (like the V392). However, it is not recommended the other way round to use a Low Drain battery in a watch with high power requirements as this can lead to functional disturbances.How should this button cell be disposed of? Button cells must not be disposed of in household waste. Please take the empty battery to the designated collection points in stores or to the municipal recycling centres to ensure environmentally friendly disposal.
