Non-rechargeable lithium batteries are manufactured for devices that use a lot of power such as digital cameras, where their high cost is offset by longer running time between battery changes, and more constant voltage during discharge.
Recommended for use with long life electronic equipment: calculators, cameras, memory backup, pocket pagers, and watches.

High energy density, long life power source - nominal 1.5 volts
Lasts up to 8 times longer in digital cameras, 3.5 hours longer in CD players, and 5.5 hours longer in MP3 players than ordinary alkaline batteries
Weighs 1/3 less than standard alkaline batteries
Operates in extreme temperatures from -40F to 140F
Up to 10 year estimated shelf life at room temperature

Note that these non-rechargeable lithium batteries (1.5 volts) have a different chemistry from rechargeable lithium ion batteries (3.6 volts)
