The battery fits my Legria HF R36 and keeps much longer than the supplied BP-709th However, the camera asks each time whether you should really use the battery since they could not communicate with him. A level indicator there are accordingly not, a red battery icon will instead appear with a question mark.
Since the Canon original but costs four times as much (without charger) I can recommend this battery despite the limitations.
I'm just wondering if you could invite to the charger and the original BP-709 ...
