How Long Do Watch Batteries Last – (And Why)?

Exact Answer: 4-6 years

Ideally, a watch battery is also known as a button cell. A watch battery is a type of battery that is in the form of a cylinder.

It is made of metal and equally resembles a button. The watch batteries are powerful and are portable batteries that are in pocket calculators, wristwatches, artificial cardiac pacemakers, and implantable cardiac defibrillators.

Some of these devices that use the button cell are designed around the cell to serve for a long period of time; for example, a watch battery can last up to one year.

These watch batteries are usually in single cells and are disposable primary cells.

How Long Do Watch Batteries Last?

For starters, we take two different types of watches that is a digital watch and an analog watch. Also, assuming that the two types of watches have the same batteries and the watches are in good condition.

The watch battery in the digital watch will last longer compared to the analog watch.

This is because an analog watches gears and moves its parts hence draining the watch. Unlike the digital watch, which does not move; hence, it saves on the watch batteries.

Below is an illustration of the type of watch and their duration of time when they can last.

Watch TypeTime
Digital Watches4-6 years
Analog Watches1-2 years

Also, the model or the design of the watch will determine how long the watch battery would last.

For example, manufacturers such as Casio watch build in their watch batteries to last up to a period of 10 years without replacement. Thus, this type of watch is not only luxurious but also it has a long battery life span.

Lastly, some of these digital watches have draining features such as backlight and alarms. The more these features are used, the more it will shorten the life span of the batteries.

Why Do Watch Batteries Last That Long?

To begin with, the life span of the watch batteries depends on the design of the watches.

High designer watches have the longest life of their watch batteries, for example, the Casio watches.

This is because their manufacturers focus building watch batteries that will last for the longest period, unlike other watches with different watch batteries.

In addition, a watch battery should stay up to 10 years before it loses its power.

If a brand-new watch stays on the shelf for a long time before it is bought, it will eventually lose power. Hence their watch battery will reduce in its life span.

Therefore, it is important not to let a brand-new watch stay on the shelves for a long period of time. This is will make the watch battery to stay for a long time.

Lastly, a wristwatch should be prevented from getting in touch with water. This is because water tends to get in the watch battery and destroys it, plus affects the normal functioning of the watch. Thus, it is very important to keep away watches from water as it shortens the life span of the watch battery.
