Battery charge with the original charger.

The bundle Star battery work in my GM1 without problems. This includes the operation of the power supply including correct display of the battery state on the camera screen. Further invites the battery in the original Panasonic charger, which in my experience in older Panasonic cameras and third-party batteries was not always the case.

The stated capacity of 600mAh, I can confirm (tested after about 5 charge / discharge cycles). A comparative test with the original battery (680mAh) shows almost 11.5% less runtime at continuous-lapse recordings.

Am satisfied with the purchase, everything as described. The 5 star there would be if he had the capacity of the original battery. Who can accept the slightly lower capacity, receives a good quality product at a significantly lower price than the original manufacturers battery.

Get at least one other of these batteries to buy me before the next holiday even here.
