Lithium batteries can easily support the brief, heavy current demands of devices such as digital cameras,and they maintain a higher voltage for a longer period than alkaline cells.

Over 95 percent of the heart pacemakers use a lithium battery to power the pacing systems, and it has a 7 to 10 year life in these applications.

A lithium battery is a type of battery used for low-power, high-reliability, long-life applications,such as clocks, cameras and calculators.
