This is the 4Sevens single-bay smart charger. It has a constant-current, constant-voltage (CC/CV) circuit. This means it will maintain a constant current to the battery until the terminating voltage (user selectable) is reached, then it will maintain a constant voltage; thus, the current is naturally reduced as the voltage approaches the terminating voltage.
The charger also offers USB charging with the included USB/MiniUSB adapter!
Caution! This charger is only compatible with the above listed rechargeable, protected battery sizes! Please ensure your battery is both protected rechargeable and compatible with the charger!
Always insert batteries into the charger with the positive terminal facing toward the "4Sevens" logo! Incorrectly inserting the battery is dangerous and may cause personal injury!
