The Firetrol® battery charger features a fully automatic 4 step charging cycle.  The charging cycles are as 
Step 1: Qualification Stage (Flashing yellow and green LEDs)
 During this stage, the battery charger checks the batteries to insure they can accept a fast charge.  It  
 also checks for missing or defective batteries.  If the charger detects missing or defective batteries a  
 fault will be given (solid red LED).
Step 2: Fast Charge (Solid yellow LED)
 Charges the batteries until they reach peak voltage.
Step 3: Bulk Charge (Solid yellow LED and slow blinking green LED)
 Charges the batteries at a constant potential of peak voltage until current reaches 500mA.
Step 4: Float Charge (Solid green LED)
 Trickle charges the batteries to maintain peak potential.
