have the battery life compared to the original battery by Canon, and made a video recording Alike. The battery was previously 2 times to load and unload, all the camera functions are disabled, off GPS and IS. The display regulated down to counteract heating and to minimize the power output. After recording (4GB limit) was once again forced to "video recording". Was recorded in full HD mode. It was chosen a rigid object to films and worked with incandescent lighting to keep fluctuations in the recording poss othing low.
Lookit the battery I could (average for 2 tests value) record 52 minutes video, the Canon battery 71 minutes.
Since I can not enter a capacity of 1200mAh at Lookit battery because the original battery has less capacity has (indicated 1120mAh)
Was on the phone with the dealer who is not entered into that the battery less line could have ... OK, then I'll have to have a defect, but this is rather unlikely.
For the price, however it is still a recommendation, because I have known reports where more favorable replacement batteries have cut significantly worse, and with even higher to the nominal capacity (1120mAh Canon original battery)
I would be there already, a further comparison of a user's interest, which under similar conditions mean is done to rule out a defect of my batteries can. It would be important, the camera in the meantime not to adjust and if possible take the same shot. With a 16GB card I had to delete or 2 times a movie file to enough space on the card to have, when Lookit this did not happen when the original Canon battery.
