Most families nowadays have so many things that use a lithium battery. Cameras and camcorders use them, and I think it’s always good to have a backup battery in case a battery runs out of power during a “Kodak moment.” If you’re needing a new battery, East Coast Photo has a newly revised “Battery Finder” where you can search for the battery you need, an expanded on-line catalog where you can also find new and innovative tools, and they have knowledgeable staff and competitive pricing.
