Introduction
The TC400 Battery Charger is electrically compatible with Sony BP-UXX Li-Ion camera batteries.
Standard Features
•
Four simultaneous charge positions for fast charging of multiple batteries.
•
Fast, safe, and reliable charging. The battery pack can be left on the charger after the charge
is complete.
•
The charger’s design is based on modern “Gas Gauge” technology. This determines battery
capacity by monitoring the amount of charge input or removed from a rechargeable battery.
The multifunction LCD display with backlight shows charge in progress data: voltage,
estimated percent of readiness, and actual amount of charge in Ah input to the battery after
battery insertion.
•
Wide range input power compatibility (100-240VAC 50-60Hz).
•
Compact, lightweight design for easy portability.
Batteries
The charger is capable of charging 4 batteries at the same time. It accepts Sony BP-UXX batteries.
Charging time
The time to full charge depends on the battery pack rated capacity, its state of charge prior to
insertion, and its age. A fully discharged new BP-U60 battery pack will be fully charged (more than
90%) in about 4 hours. Since a depleted battery pack absorbs charge current faster, than a partially
charged one, most of the charge energy is absorbed during the initial stage of charging and then the
rate of charge levels off towards the end.
Charge channels
All 4 charge channels are fully independent from each other; charge initiation and termination
depend on a battery’s state of charge. An LCD display indicates each battery’s state of charge, in
voltage, percent of readiness (estimated), and amount of charge in Ah input in it since the battery
insertion.
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.
