Introduction
The TC400 Battery Charger is electrically compatible with all 7.2V Li-Ion camera batteries rated
2200mAh or higher. The modular design allows for different battery models to be charged and tested
when the appropriate adapter plate is fitted. Because the charger is software controlled, its
functionality allows for flexibility in charging and testing of batteries used. In addition to charging,
battery testing and camera power supply options are available. With the appropriate power cord, the
charger can be powered by a 12V automobile power source.
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 mAh input to the battery
after battery insertion.
• Wide range input power compatibility (100-240VAC 50-60Hz), 12V with the DC cigarette
lighter cord.
• Compact, lightweight design for easy portability.
Expansion Options
Thanks to modular design and software based functionality, the charger provides ultimate flexibility
for various video applications. Several expansion options are available.
• Test/discharge circuit for complete battery characterization.
• Camera power 7.2V (up to 1A)
• Automobile power source using the DC cigarette lighter cord.
Batteries
The charger is capable of charging 4 batteries at the same time. It accepts Sony L/M (VX2xx or
similar), Panasonic DVX100/HVX200/HMC150, Canon BPxx (XL/GL), and JVC BN-VF823 style
batteries. The charger must be configured with the appropriate plate to match the battery style.
The battery must to be rated at least 2200 mah capacity, as smaller size battery packs are not
designed to accept the charger fast charge.
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 2800 mAh battery pack will be fully charged (more than
90%) in about 2.5 hours. A 5600 mAh pack will take approximately 3.5 - 4 hours to charge. 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
