Charging indicator LED is the weak point

I'll start with what wrote the manual for charging LED. If the battery is charged, the LED flashes red. If the battery is full, the LED is off. Now arises from the formula for charging batteries - Kappazität the battery's divided by the charging current of 1.4 times Ladegrätes - that the battery pack 16,8h would depend on the cable, as the Chargers 1000mA has output power. This is personal to me long. I had the battery 13h on the can and thus the LED blinked yet. Now describes the owner's manual that when the battery is full, the LED is blue, red at 75% pink, 50% and at 25% it flashes blue. My experience is ensuing. At the beginning of the first charge of my Galaxy i9000, the LED lit red. Means 50% battery charge condition after 13h. Even crap. And now it is even funnier. Second charge, at the very beginning it flashes blue. So almost empty. When I think like that. Third charge a Nexus, it is still blinking blue. Smartphone was full after just under three hours. What do you think of this? I'll send it back because if I do not know exactly how many because really is still Restkappazität the battery, it is useless to me when I run five days through the mountains and then sometime stand in the plains and had no more juice.
The connectors that are included, by the way look like from the dollhouse. I used a high-quality charger.

I hope I could help.
