voltage, percent of readiness (estimated), and amount of charge in mAh input in it since the battery
insertion.
Test/Discharge circuit (optional)
With the Test/Discharge circuit installed, the charger becomes a complete battery management system
enabling battery characterization, as well as identifying anomalies resulting from aging and other deficiencies.
The test performed is a full charge-discharge-full charge routine. This test will identify the true capacity of the
battery displayed on the LCD panel. The discharge circuit closely approximates actual real life discharge, as
seen by the battery in normal camera use. The circuit is associated with channel 1.
Camera Power Output (optional)
The camera power supplied is 7.2V up to 1.5A. The charger is capable of providing camera power, while
charging batteries. When all 4 fully discharged batteries are inserted, the rate of charge will be automatically
reduced as needed in order to balance total power consumption. This results in a slight lengthening of the total
charge time.
Operation
Charging
Operation of the charger is fully automatic. Mount any battery to any open position on the charger
and the charger will initiate the charge routine. While charging is in progress, the LCD display will
indicate the battery voltage, estimated readiness in percent, and amount of charge accepted by the
battery. Upon charge completion, the display will report the position number (1-4), amount of charge
the battery has absorbed, and the completion message.
Upon the battery insertion, the charger will identify the battery’s state of charge, and initiates the
appropriate charge regimen. If the inserted battery is fully charged, it cannot safely absorb charge.
The charger will display the “ # 1(2,3,4) Ready” message.
Note:
• Estimated readiness is intended for the “charge in progress” status information. Accuracy may vary for an old
or new battery, and between different sizes and makes.
• Amount of charge absorbed by the battery is displayed from the moment of insertion. If a fully depleted
battery charged in full, the charge displayed is equal to the actual battery capacity in mAh.
• Upon the battery removal, please wait 2-3 seconds before inserting a new battery in the same position, as the
charger channel needs this time to initialize.
Status LEDs
LEDs help to quickly identify charging state.
1. Fast blink Battery is inserted; charge in progress
2. On Battery is ready (charged over 90%)
3. Slow blink Test in progress
Testing (optional feature)
• Insert the battery to be tested in position 1.
• Press “Test” button
A letter “t” will be displayed while channel 1 status information is shown
The charger will fully charge the battery, fully discharge using its internal load (LCD will display
“Discharging”), and then fully charge for complete readiness. The amount of charge delivered to the
load is displayed on the LCD panel. This is the true battery charge capacity in mAh.
