Once you choose the perfect electronic clock for your home you will need to power it. Many clocks in the modern age are powered by batteries, anywhere from button cells to D cell batteries. But once you power up your clock, how long should it last? Is it a matter of months before your batteries run out or could it be years?

The earliest electronic clock were French-made electromagnetic clocks. If you are looking at more of an antique look and opt for one of these, although they are pricey, the batteries in these clocks can last up to 10 years! They may be a more expensive choice, but it does minimize the need to change batteries quite so often

The more likely option is a modern electronic clock. Most of these you will find the batteries can last anywhere between one to two years. Any clock with a quartz movement is a much more economical choice so these use less power and as a result the batteries will last for a longer period.


Another factor that can impact your clocks battery life is the size of the clock and subsequently its movement. Small quartz clocks, such as watches, last a lot longer period while large wall clocks can last around 12 months.

In addition, similar clock movements can take different sized batteries. There are a range of choices, anywhere from a button cell to large D cell batteries. The general rule of thumb is the battery size does affect the length of time that the battery will last. The bigger the battery, or the more batteries that you have in the clock can allow your new clock to last for longer.
