Question
The battery-low indication shows that the battery needs to be recharged, but I can still use the appliance. How is this possible?
Answer
The battery-low indication warns you some time before the batteries are completely exhausted. The shaving time left after the the battery-low indication is shown should be regarded as backup capacity. The amount of backup capacity depends on the condition of the batteries, the ambient temperature and whether the general battery maintenance precautions are being observed.
