    Abstract: An energy-efficient and compact multi-port battery charger. The battery charger includes, among other things, a power supply module, a battery charger control module or controller, a power switching module, one or more power control safety modules, a plurality of battery charger switches, and a plurality of indicators. The controller, the power switching module, the power control safety modules, and the battery charger switches work in conjunction with each other to control the operation of the battery charger. The controller is configured to execute a charging control process which detects the insertion of a battery pack into a charging port, selects a charging port for charging, controls the power output from the power switching module, and controls the illumination or display of the indicators. The power switching module uses control signals from the controller to switch the power received from the power supply module such that a charging current is applied to a single charging port. Each of the power control safety modules includes a power control safety circuit that is configured to prevent the charging current and/or the charging voltage from damaging the battery charger or battery pack during a malfunction.

    Abstract: A battery tester engages a power tool battery and includes a housing having a cavity for receiving a stem of the power tool battery. The battery tester has a plurality of electrically conductive contacts disposed in the cavity and is configured to engage corresponding battery electrodes on the stem. A processor is mounted within the housing and communicates with the battery through the electrically conductive contacts. The processor measures a voltage level of the battery, and a loading circuit electrically loads the battery during measuring. One or more indicators are controlled by the processor. The processor activates the loading circuit for a predetermined period of time to measure a voltage level of the battery while under load, and then activates the indicators to provide a visual indication of remaining battery life. The battery tester is a stand-alone device where housing does not have a motor or a battery charger.
