Question

How can I optimize the lifetime of the rechargeable battery?

Answer

This appliance contains a NiMH battery (or batteries - depending on the model).

To extend the lifetime of your rechargeable battery, please take the following into consideration:

  • First time charging: charge it roughly 3 times longer than the normal charging time.
  • When the appliance has been charged for the first time, we advise you to use it until the battery is completely empty. Do not recharge the appliance in between sessions if not needed.
  • Remove the adapter from the wall outlet when the battery is fully charged.
  • Let the battery run down completely at least once a year and fully charge it afterward.
