Photo Primus Replacement Battery for Panasonic - CGA-S006 with excellent 1200 mAh capacity for FZ30 / FZ7 / FZ8 / FZ18. Product comes from China. According to imprint the battery even has 1300 mAh capacity. Outwardly he looks up at the lettering almost like the original. First, very pleasing. But unfortunately he did not fit in the Lumix FZ18. After insertion into the battery compartment latch can not lock into place over the battery, because the battery can not be inserted deep enough into the well or because it is too long. To avoid the hassles of returning I have filed the battery housing smaller. Now it fits into the camera. The fit of the original but is far from being reached. I would like to spend the next purchase a little more, if I may thus get the original or a tailor-made alternative.
