SONY clone or original?

in July 2012 I bought a reference battery "SONY NP-FV100" for my camcorder SONY HDR-CX740. This battery was shipped to me by Emania Pro blister to the brand SONY, and she never gave satisfaction with the load capacity and duration of operation. Today, after a full charge and a few hours of rest, the battery is fully discharged.

I just bought, on 14 February 2013, with another provider, a new SONY NP-FV100 battery that gives me satisfaction and that does not look the same as the one sent me Emania Pro.

Several differences in housing color, print color text on the label of electrical contacts (4 on battery Emania pro, 3 on the battery). Significant weight difference is noted: 116g for the battery Emania Pro, 189g for the new battery.

On the other hand, the battery Emania Pro covers its box brand hollow D35J that is not present on the battery and the plastic part containing the electrical contacts 4 is light gray while the new battery color is the same as that of the case.

I wrote Emania Pro to obtain compensation. The answer came: the purchase of 8 months and the guarantee offered by Amazon is only 90 days ...

I suggest not to book with e-Mania Pro ...
