Used Dolgin Engineering TC200-i 2-Position Charger with Diagnostics LCD Display for Sony NP-FZ100 batteries

The TC200i Battery Charger is electrically compatible with all 7.2V/14.4V Li-Ion camera batteries rated 900mAh 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 option is available.

Auto-detecting fast charging USB port for recharging tablets, handsets, personal media players and other portable devices (Apple, Android, etc) works when AC power is available, and on-the-go when at least one charged battery is available.(This model is used to charge Panasonic DMW-BLJ31 batteries)

With the appropriate power cord, the charger can be powered by a 12V automobile power source(except for the -EX configuration).

Batteries
The charger is capable of charging 2 batteries at the same time. It accepts Panasonic DMW-BLJ31 batteries. The charger must be configured with the appropriate plate to match the battery style. The charger is also compatible with non OEM 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 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
Both 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 mAh input in it since the battery insertion.

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 (1-2), amount of chargethe 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) Ready" message.
