Battery charger having charging completion indicator

A battery charger comprising:

• a temperature sensor for detecting a temperature of a battery;
• a charging completion sensor for detecting a fully charged state of said battery;
• means for controlling a charging of said battery, said controlling means suspending the charging of said battery when said temperature sensor detects a temperature of said battery higher than a first predetermined temperature, said controlling means restarting the charging of said battery when said temperature sensor detects a temperature of said battery lower than a second predetermined temperature, said second predetermined temperature being lower than said first predetermined temperature, and said controlling means stopping the charging of said battery when said charging completion sensor detects said fully charged state of said battery;
• and
• means for displaying a charging completion indication when said temperature sensor detects a temperature of said battery higher than said first predetermined temperature a predetermined number of times.

A battery charger comprising:

• a charging power source for supplying a charging current to a battery;
• a temperature sensor for detecting a temperature of the battery;
• and
• means for controlling the battery charger, said controlling means including:
• means for starting the charging of the battery when the temperature sensor detects a temperature below a predetermined temperature;
• means for suspending the charging of the battery when the temperature sensor detects a temperature of the battery above the predetermined temperature;
• means for restarting the charging of the battery when the temperature sensor detects a temperature of the battery below the predetermined temperature;
• and
• means for displaying a charging completion indication when charging of the battery has been suspended a predetermined number of different times.
