Hopefully not too much promised

Despite Amazon Prime very long delivery time, because the batteries come from Scotland.
The stated capacity of 1500 mAh is higher than the original battery, because I have my doubts. According to photo is only 1250 mAh.
I'll measure it and report.

Addendum: Appointed: 12.05.2014 05.16.2014 received via UPS. Very professionally packaged.
Imprint on Battery: 1500 mAh, so would the capacity 50% higher than the original battery.
I can not test, because ordered Camera + charger has delayed delivery.

Addendum of 07/01/2014
By now I had a chance to try the supplied batteries. They fit into my Panasonic DMC-GX7 and also work in it. A fully charged battery is recognized as fully. The batteries I have loaded the original Lumix charger and then measured with a capacitance meter the true battery capacity during discharge outside the camera.
The first battery is 716 mAh, and the second 724 mAh. Measured at a discharging current of 240 mA. At a higher discharge current as in the camera, a smaller capacity can be expected. For smaller current capacity is slightly larger. Specifically, there are 20 mAh more at only 100 mA discharge current.
In comparison, the original battery supplied with the camera: Measured Capacity 1040 mAh at 240 mA discharge current. Printed nominal capacity 1025 mAh.

Conclusion: Both batteries have virtually the same capacity of 720 mAh, which is not even half the printed capacity of 1500 mAh. There are only 70% of the capacity of the original battery, although the dealer promises a significantly higher capacity.
Legally there is fraud, a battery for sale, its performance is so far from the promised value. It takes courage to promise the moon such values. The customer is stupid and it will hardly notice!
Technically I have received second-rate batteries for a reasonable price. Therefore, I will not send them back. If the dealer is reading this and thinks to have copies with the promised features (which I exclude), he should contact me. Then my rating could improve again.
