With this battery it is possible to shoot many photos on a single battery charge.
The NB10L battery communicates with the Canon PowerShot SX40 series camera, so that you can always check the remaining capacity, shutter count and recharge performance on the cameras power source info screen.
This battery features Lithium Ion technology, which ensures maximum battery life and maximum power. Also, Li-Ion batteries are lightweight and can be charged or discharged at any time without developing so called “memory effect”, so they never lose their ability to hold a full charge.
