Li-ion Battery for Canon G11

This battery works with your camera and your charger with no problems. But he has a significantly lower capacity than the original battery of Cannon. This is probably attributable to the lower nominal voltage. Original battery = 7.4V, Battery = 7.2 V. Given the price difference but it's worth it to pick up the spare.
If you want to use it for travel with no possibility of recharging, but one should take into account a greater number of pieces.
