Watch Batteries for all your timekeeping needs

We all wish we could stop time every now and again but when those little hands on our watch stop turning it can throw us for a loop and get us into some serious trouble. Luckily on eBay you can find a huge selection of watch batteries to get you back on track.

Whether it's a beloved heirloom or a new timepiece, you'll be able to find a compatible battery without the hassle. Choosing the right watch battery size can be confusing which is why we've put together a short guide to help you find the right match.

Choosing the right watch battery for you

As the most popular option for watch batteries, silver oxide is often chosen over alkaline batteries due to its high voltage output. With most watches requiring 1.55 volts to tick away happily, alkaline batteries are 1.5 volts, not 1.55 volts as they're often mistaken for, which would underpower your watch and give you the incorrect time.

The main point of difference between silver oxide and alkaline batteries is that silver oxide batteries like the Sony SR626SW Coin Battery has a very flat profile. In short, this means that they continue to produce 1.55 volts until they are completely exhausted, which is beneficial for watches which stop working at 1.3 volts or less. Whereas alkaline watch batteries will typically stop working when they get to 0.5 volts.

However, alkaline batteries such as the SR66 Coin Battery is perfect for toys, decorations and some low powered watches. As the successor to mercury, silver oxide batteries have twice the capacity of alkaline batteries meaning they will last longer, they also tend to be slightly more expensive as a result.

Depending on your battery needs, on eBay you will find a watch battery that will keep you going around the clock.
