The voltage remains stable over almost the entire lifetime of the battery, which ensures the precision of the device. The high energy density enables a long runtime in a very small size. Thanks to minimal self-discharge, the battery is also extremely long-lasting in storage.Efficiency and safety for your watch movementVarta watch batteries are subject to the strictest quality controls to ensure consistently high performance and maximum safety. The high-quality workmanship and sealing of the V364 cell provides reliable protection against leakage and thus protects the sensitive movement from damage. Trust in tested quality for your valuables. Characteristics  ModelVarta V364 / SR621SW TechnologySilver oxide-zinc (Low Drain) SizeSR621SW / 364 Nominal voltage (V)1.55 Capacity (mAh)approx. 19 Dimensions (Ø x H, mm)approx. 6.8 x 2.1 Weight (g)approx. 0.3 RechargeableNo  FAQs about the Varta V364 watch batteryWhat does the designation SR621SW mean?The international IEC designation provides information about the battery. "S" stands for silver oxide, "R" for the round shape, "621" for the dimensions (6.8 mm x 2.15 mm) and the "SW" at the end marks a "Low Drain" version. This is specially optimised for devices with low and constant current consumption, such as wristwatches.Is this battery compatible with the designation SR60SW?The Varta 364 corresponds to the internationally standardised IEC designation SR621SW. The designation SR60SW is not standardised. Please check the number on your old battery. If it says 364 or SR621SW, this is the correct replacement.Can I replace an LR621 alkaline battery with this V364?Yes, this is possible in almost all cases and represents a clear upgrade. The V364 (SR621SW) offers a longer service life and a more stable voltage, which improves the accuracy of your watch. For high-quality watches, the use of a silver oxide battery such as the V364 is strongly recommended.How should this watch battery be disposed of?Watch batteries must not be disposed of in household waste. Please take the empty battery to the designated collection points in shops or municipal recycling centres to ensure environmentally friendly recycling.

The Varta V395, internationally known as SR927SW (or SR57SW), is a premium silver oxide button cell that is characterised by its particularly flat design. As a "low drain" battery, it was specially developed for the long-lasting and reliable power supply of classic analogue watches. Its stable voltage of 1.55 V guarantees maximum accuracy and its slim shape makes it the ideal choice for elegant and extra-flat wristwatches.Highlights at a glancePremium quality: High-quality silver oxide technology for maximum reliability.Low drain optimised: Perfect for the low, constant energy requirements of analogue watches.Flat design: Ideal for particularly slim and elegant watch cases.Long service life: High energy density for a service life of several years.Tested quality: High leak resistance to protect your valuable movement.Precision energy for elegant timepiecesThe Varta V395 was specifically designed for use in high-quality analogue watches where a flat and elegant design is paramount. Its cell chemistry is designed to deliver a minimal but constant current over a very long period of time. This not only ensures a long running time, but also the highest precision of the movement, as is expected of quality watches.Reliable silver oxide technology (low drain)The "Low Drain" technology of the V395 is designed for maximum energy efficiency and minimal self-discharge. In contrast to "high drain" batteries, which are designed for high power peaks, the focus here is on maximising service life with a low continuous load. The silver oxide base guarantees an absolutely stable voltage until the end of the life cycle and thus prevents a drop in accuracy.Efficiency and safety with a systemEvery Varta battery undergoes strict quality controls to ensure consistently high performance and maximum safety. The V395 is optimally protected against leakage thanks to its first-class design, which protects your valuable movement from damage. The secure individual packaging also protects the cell from environmental influences and short circuits until it is used. Characteristics  ModelVarta V395 / SR927SW Battery typeSilver oxide watch battery Rated voltage (V)1.55 Capacity (mAh)42 Diameter (mm)9.5 Height (mm)2.7 Weight (g)0.6 Alternative designationsSR927SW, V395, D395, SR57, 280-48  FAQs about the Varta V395 / SR927SW button cellWhat do the designations SR927SW, SR57SW or 395 stand for?These are designations for the same battery size. SR927SW is the most common international IEC standard. "S" stands for silver oxide, "R" for the round shape, "927" for the dimensions (9.5 mm diameter and 2.7 mm height) and "SW" for "Low Drain". SR57SW is an older IEC standard for the same size. The 395 is the specific type number of the manufacturer Varta.What does "Low Drain" mean and for which watches is it suitable?"Low drain" means that the battery is optimised for low, constant power consumption. It is the ideal choice for classic, analogue wristwatches without energy-intensive additional functions. Thanks to its flat design, it is particularly suitable for elegant and slim watch models.Can I use this battery in a watch with a light or stopwatch?This is not recommended. For watches with such functions, a "high drain" battery (with the suffix "W", e.g. Varta V399 / SR927W) is the right choice. The use of a low drain battery in such a watch can lead to malfunctions and greatly shorten the service life of the battery.How should this button cell be disposed of?Button cells 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.
