I bought this charger DTC in 5101 for lack of availability Subtel here. This charger is ideal for charging batteries original SONY, less compatible for want of correct voltage. The batteries are not loaded "block". A small modification to address them in the adapter plate (His FP50), two screws to disassemble, solder resistance of 68 K between the point of measurement (free lug) and negative (black wire) and you adjust the voltage and burden on rechargeable 7.4V instead of 6.8V. Note that we also undertake the SONY original, but does not insist on completion of charging (when clignottement LED orange).
