Abstract: A rechargeable cleaner includes a body, a rechargeable battery, a charger, and a body controller. The body is configured to generate suction power capable of sucking dust together with air using a motor. The rechargeable battery is configured to supply electric power to the motor. The charger is configured to charge the battery. The body controller is disposed in the body. The body controller controls at least one of a charging current and a charging voltage based on cell voltage information indicating a cell voltage, cell temperature information indicating a cell temperature, and battery identification information for identifying the battery that are acquired from the battery, and based on charger identification information for identifying the charger acquired from the charger.
