Charging immediately after receipt, the battery does not seem to operate the LEDs of the original charger 7D (hard to know when it is loaded!). Otherwise, in this device works and battery to an identifier such as Canon and the percentage of battery charge is displayed.
There currently are no test required to load or longevity, I received the battery yesterday.
EDIT: finally good battery not charging, surely why the charger LED lights not I ... it makes me a disposable battery that has just earned me a galley in Hawaii, not cool.
