The ARE-A4 Battery Charger from Fenix Flashlight has four bays to charge nine different types of Li-ion, NiMH, and NiCd batteries. It charges batteries either at the same time or independently. The included AC charging cable plugs directly into the charger and then to the wall, but you also have the option of DC charging via the car adapter, which is sold separately. During the charging process, the LCD screen displays the battery type, the voltage, the status, and the time remaining for the battery to fully charge. The smart charger has built-in protection against over-current, over-voltage, short-circuit, and reverse-polarity. Push the control button above each bay to cycle through the battery information on the screen or turn the screen on or off by holding the button down for longer.
