In 1957, Energizer (then known as Eveready) produced the first commercial watch battery.
We stock the very highest quality watch batteries, including a comprehensive range of Seizaiken (Seiko), Duracell, Rayovac, Renata, Murata (Sony), Energizer, Varta, and Maxell products.
Many Energizer batteries are 'multi-drain', meaning they cover both low drain and high drain applications. This is why they are often numbered with two numbers, since they cover both the low drain and the high drain variants of batteries with the same physical cell dimensions.
