I have chosen this battery, because it is the recommended Canon battery with long service life. Aside from the price, which, clearly is common to high as Canaon, I can at a cheaper part from another manufacturer, not tell the difference. But I think in order not to expose himself in damage to the high-quality camcorder HF G10 to the manufacturer's accusation of having used no original part, it will be better to use this battery. As I have mentioned already but initially, the price should be lower by at least 40%.
