DESC: Don't forget a spare battery! There's nothing more frustrating than having your digital camera run out of power before you're done snapping shots. Keep the NB-1LH lithium ion battery on hand to pop into your Canon Digital ELPH when the original battery runs out. This handy lithium ion battery pack powers your camera for up to 420 photos with the LCD off. (Battery life will vary with model, usage, temperature, and humidity.) And unlike NiCad batteries, lithium ion batteries have no ""memory effect"" to reduce their capacity.
