Using the Battery Analyzer
The fourth charging slot is also the CHARGE/ANALYZE slot because, in addition to charging a Li-ion
battery, this slot runs an Analyze cycle on the battery placed in it, which helps you monitor battery capacity
over time.
Analyze Button
The Analyze cycle is initiated when a battery is placed in the Charge/Analyze slot and the Analyze button
is pressed. In an Analyze cycle, batteries are completely discharged, then recharged to capacity. The
battery is completely reset and re-calibrated.
The amount of time required for a battery to complete the Analyze cycle depends on initial state of the
battery’s charge. Minimum time is 8 hours, maximum time is 12 hours.
Battery Capacity Indicator LEDs
These LEDs display the charge capacity of the battery at the end of the Analyze cycle. Battery capacity
is displayed as a percentage of measured capacity/rated capacity where each LED equals 10% battery
capacity. At the end of the Analyze cycle, these LEDs display the maximum charge level the battery can
now hold.
Status LED
The Charge/Analyze slot also contains a standard status LED in the upper, left corner of the slot. When
this slot is used for regular charging, this LED operates in the usual manner; see Status LEDs on page
10-2.
When this slot is being used to analyze a battery, its status LED functions as follows:
Solid Green The battery has completed the Analyze cycle.
Flashing Orange The battery is currently being analyzed.
Solid Red The QuadCharger
device encountered an error during the Analyze cycle.
To Analyze a Battery
1. Insert the battery into the Charge/Analyze slot (the fourth).
2. Press the Analyze Button (page 10-2). The Status LED flashes orange to indicate that the analyzing
cycle has begun.
3. Upon completion of the Analyze cycle, the Status LED lights solid green, and the Battery Capacity
Indicator LEDs display the battery’s capacity.
The Charge/Analyze slot is accumulating battery pack information during the entire Analyze cycle. Do NOT
remove the battery until the cycle has been completed.
