Abstract
A battery-powered apparatus having a battery (B1), detection means (IC1) for detecting a discharge condition of the battery, and signaling means (D) for indicating the discharge condition of the battery, as well as discharge means (R5, T1) which are activated by the detection means when a predetermined first discharge condition of the battery is reached, in order to discharge the battery in a controlled manner until a predetermined second discharge condition of the battery has been reached.
Claims12
A battery-powered apparatus having a battery, detection means for detecting a discharge condition of the battery, and signaling means for indicating the discharge condition of the battery, characterized by discharge means which, when a predetermined first discharge condition of the battery is reached, are activated by the detection means to discharge the battery in a controlled manner until a predetermined second discharge condition of the battery is reached.
A battery-powered apparatus as claimed in any one of the preceding claims, characterized in that the predetermined second discharge condition lies at a predetermined second voltage level (V2) below the voltage level for the first predetermined discharge condition.
A battery-powered apparatus as claimed in any one of the preceding claims, characterized by an electronic circuit arrangement including a detection circuit for detecting that the first and the second predetermined discharge condition are reached, and including a discharging circuit for discharging the battery, which discharging circuit is activated when the first discharge condition is reached and is deactivated when the second discharge condition is reached.
A battery-powered apparatus as claimed in any one of the preceding claims, characterized in that the apparatus is an electric shaver and the controlled discharge takes less than 24 hours.
