About the device's built-in rechargeable battery
You cannot replace the built-in rechargeable battery yourself.
If the battery does not retain its charge for as long as it used to due to prolonged use, it may have reached the end of
battery life. In this situation, contact our service centre.
The average service life for the battery is five years, although this may change depending on the operating conditions.
