I purchased the battery about a year ago. I've always used the original Nikon charger and the battery normally flashes as long in the station until the steady light indicates the full charge. Now, the battery charge status indicator blinks three times faster than usual. When inserting into the camera, I realized that he has barely gotten charge and therefore is useless. After such a short time and for this price it is a disappointment (had relied on the judgment Chip.de).
