The TC400-SON-TDM from Dolgin Engineering features integrated battery plates that support Sony and third-party NP-F970, NP-F770, and NP-F975 batteries. These batteries are used with Sony's HD1000U, Z5U, Z7U, MC2000U, NX5U, HDRFX7, and FS700R cameras.
The TC400-TDM has an LCD screen on the front panel that displays charge status in volts, amp hours, and percentage of charge that's estimated using a proprietary algorithm. The TC400-TDM is also designed with a built-in Test/Discharge Module that allows you to determine whether a battery is new or old, and whether it's on par with its label. The TDM feature cycles the battery (fully charges and discharges it) and then provides a report on its capacity.
The TC400-TDM has fully independent channels and provides simultaneous charging to all four batteries. Based on a capacity of 5600mAh, this particular model delivers a complete charge in approximately 3.5 hours for four batteries or when you charge a single battery.
The charger comes with a U.S. power cord and supports worldwide power input via optional plug adapters, as well as 12 VDC car lighter power via an optional car lighter adapter (model # DE_CAR_12).
