Highlights for Canon Battery Pack NB-4L
There's nothing more frustrating than having your digital camera run out of power when you really need it. Don't miss another shot — keep the NB-4L rechargeable battery on hand to pop into your compatible Canon camera when the original battery runs out. Since it's a lithium ion battery, partial charging and discharging won't reduce its capacity over time.
