The Seizaiken 394 battery is manufactured in Japan by Seiko Instruments Inc., one of the most reliable watch battery manufacturers in the world. It utilizes Silver Oxide chemistry to provide a continuous, perfectly stable voltage of 1.55V throughout its lifespan. This stability is vital for delicate quartz mechanisms, ensuring that your watch will not lose time and will operate with exemplary accuracy.

One of the most important advantages of Seizaiken (Seiko) batteries is the specially designed sealing structure with an anti-corrosion coating. This technology protects the sensitive and expensive mechanism of your watch from electrolyte leaks, even when the battery is nearing the end of its lifespan. You can be completely confident that your device remains 100% safe and protected from internal oxidation.

The type 394 fully corresponds to the codes SR936SW, SR45, V394, D394, and AG9, making this battery perfectly compatible with a wide range of analog and digital wristwatches from top market brands. Additionally, it is suitable for use in precision medical instruments, calculators, electronic games, and small sensors. It is available in an individual sealed package of 1 piece to maintain full charge until the moment of installation.
