What Battery Do I Need For My Casio G Shock?

In general, a Casio G-Shock watch uses a lithium cell or a light-powered battery.

The former can last about 2 years, while the latter can last a maximum of 15 years using light-receiving panels on the surfaces to receive and convert sunlight, even with weak illumination.

What Affects Battery Life?

A G-Shock battery, especially a lithium cell one, can be drained by the following factors.

Frequency of use

First, the more frequently you use the features of the watch, the shorter it lasts.

Besides automatic features such as atomic timekeeping, tough movement, or sensor technology, these watches also have other helpful functions, including a stopwatch, an LED screen, backlight, GPS, or chronograph.

Using them regularly means you consume more energy so that the batteries will degrade faster.

Environmental conditions 

Most watches are designed to run consistently in normal conditions (including temperature and humidity).

Therefore, when the weather becomes much hotter or more humid, the batteries' temperature will increase, exhaust more energy, and decrease their life.

When Would The Battery Need Changing?

That a regular watch stops running means that its battery is completely drained and needed changing.

For a Casio G Shock, several signals can help tell you about the right time:

  • LCD: for models without power indicators but LCDs, you may think about changing the batteries if the displayed numbers are dimming. 
  • Backlight: you may easily recognize the backlight feature running no more appropriately. For example, it doesn’t illuminate when you turn it on but gradually appears when you turn it off. 

So, how much does it cost to replace a Casio watch battery?

On average, you may pay around $25 for a full-packaged service, including the price of the battery itself.
