The Fenix ARE-D1 Smart Battery charger is ready to charge all your different types of rechargeable batteries. The three charging currents on the Fenix ARE-D1 include 0.5, 1.0, and 2.0 amps for a variety of different battery types. You can safely charge all your Fenix batteries with the four tiers or protection including short circuit, over current, over voltage and reverse-polarity protection. Battery life is extended thanks to the micro-computer chip inside the ARE-D1 charger that controls and regulates digital charing. Another added feature of the ARE-D1 Charing is the ability to use it as a power bank via the USB discharging port. You can easily see battery charge information and current with the high-definition LCD screen.
