Using the Battery Analyzer
Purpose
Using the Charge/Analyze slot helps you monitor the charge capacity of Li-ion batteries over time.
Location
The battery analyzer is located in the 4th slot - named the Charge/Analyze slot - of the ChargeBase. Only
a battery placed in this slot can be run through an Analyze cycle. This slot contains Battery Capacity LEDs
along the right side.
Analyze Cycle
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 length of time it takes for a battery to complete the Analyze cycle
varies depending on the initial state of the battery’s charge. Minimum time is 8 hours, maximum
time is 12 hours.
Battery Capacity LEDs
The Battery Capacity LEDs are located along the right side of the Charge/Analyze slot. Each
LED equates to 10% battery capacity. These LEDs display the capacity of the battery at the end
of the Analyze cycle. Battery capacity is displayed as a percentage of measured capacity/rated
capacity.
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
14-2.
When this slot is being used to analyze a battery, the Status LED functions as follows:
To Analyze a Battery
1. Insert the battery into the Charge/Analyze slot (the 4th).
2. Press the ANALYZE button. The Status LED flashes orange to indicate that the analyzing cycle has
begun.
The charger is accumulating battery pack information during the entire Analyze cycle. Do NOT remove the
battery until the cycle has been completed.
3. Upon completion of the Analyze cycle, the Status LED lights solid green, and the Battery Capacity
Indicator LEDs display the battery’s capacity.
You can verify a battery’s capacity by installing the battery in a terminal and checking the power; see
Power on page 6-12.
