Battery Change in Polar Product


Battery life time depends highly on how much you use the product. For estimated average battery life of your Polar product, please refer to product .

For many Polar products the battery is inserted at the factory. In the package, even though not active, the battery still has shelf life. The actual life of the first battery, once the product is in your possession, can therefore feel shorter than what is estimated in the user manual.

Depending on the training computer model you can either change the battery yourself or you need to have it changed by a Polar-authorized service center that only use Polar-approved components. With every battery change, Polar performs a full periodic and water resistance check.

You can change the battery yourself to these products:
- AW200

- CS100 / CS200 / CS400 / CS500 / CS500+ / CS600 / CS600X

- Excessive use of the backlight and sounds reduces battery life.
- In cold conditions, the low battery indicator may appear but will disappear when the temperature rises.
- If your training computer has a data transfer feature, transfer all data from your training computer to related software/web service to avoid data loss.
