What is the difference between the Fenix ARE-C2+ battery charger and the older Fenix ARE C2 battery charger?
The new LCD screen is much sleeker and better looking than the previous model. The charger can now automatically detect what kind of battery is inserted and adjust the charging operation accordingly. You can also display more with the LCD screen. There are also some internal improvements that can adjust the output levels depending on the type of battery in order to protect the charger and battery.
