What kind of battery does a PROTREK use?

Any PROTREK watch uses a coin battery, but it is not the same for all watches. We composed a table that will help you to choose the battery you need. You should only examine the rear cover of the case to know the module number or the watch’s name.

What is the PROTREK battery size?

All PROTREK batteries are different, depending on the watch series. You may find the size of your battery by using our table and finding the battery type you require. For example, if you know your PROTREK is compatible with CR2016 batteries, you can find out its size at any store.

PROTREK Battery Replacement Steps?

We insist on replacing the battery only through the authorized CASIO service centers. However, if you prefer a do-it-yourself approach, we recommend the following guides:
How to Replace a G-Shock GA201-1A Battery
Casio G-Shock G302 Battery Replacement
[YouTube] How to Change a G-SHOCK Watch Battery

Do you have PROTREK WR20BAR Battery?

The battery usually isn’t dependent on Water Resistance characteristics. So you just need to know the battery type your PROTREK supports. Use our table to know it.
