How can I optimise the lifetime of the rechargeable battery?
- When the appliance has been charged for the first time, it should be used until the battery is completely empty before it is recharged.
- Follow this procedure at least twice a year.
- Do not recharge the appliance unless the performance decreases and do not charge for more than 24 hours.
- The full running time like indicated in the user manual will be obtained after fully re- and de-charging the device 3 times.
