The Fenix ARB-L14-1600U battery is a great replacement for the standard AA battery, due to it's voltage of 1.5V (as opposed to 3.7V with standard rechargeable li-ion batteries) and includes a protection circuit anode to help prevent over charge/ discharge. When the ARB-L14-1600U Battery is plugged in for charging, you'll notice a red light on the positive terminal end of the battery, and when its fully complete it will turn blue indicating you're good to go.

Please note: this battery may only be charged via it's USB port, and should NOT be used in Fenix's battery chargers.
