14.8.4 Cell and Battery Sizes
The Li/MnO cells are manufactured and commercially available in a number of flat and cylindrical
2
batteries ranging in capacity from about 30 mAh to 11.1 Ah. The physical and electrical character-
istics of some of these are summarized in Table 14.18. in some instances interchangeability with
other battery systems is provided by doubling the size of the battery to accommodate the 3 V output
of the Li/MnO cell compared with 1.5 V of the conventional primary batteries, for example, battery
2
type Cr-V3. Table 14.19 shows the characteristics of two commercially available thin cells in foil-
laminate packaging.

14.8.5 Applications and Handling
The main applications of the Li/MnO system currently range up to several ampere-hours in capac-
2
ity, taking advantage of its higher energy density, better high-rate capability, and longer shelf life
compared with the conventional primary batteries. The Li/MnO batteries are used in memory
2
applications, watches, calculators, cameras, and radio frequency identification (rFiD) tags. At the
higher drain rates, motor drives, automatic cameras, toys, personal digital assistants (PDAs), digital
cameras, and utility meters are excellent applications.
