used for low-rate drain. Cylindrical batteries with the inside-out construction can
serve as a memory backup power source. Cylindrical batteries with the spiral
construction, as mentioned above, are suitable for high-rate drains such as strobe
light sources and camera autowiding systems, and will spread to various other
fields, as high-power sources for cassette tape recorders, high-performance lights,
8 mm VTRs, LCD TVs, mobile telephones, transceivers, and other highly portable
electronic equipment. Tables 2.1–2.4 show the specifications of coin-type, cylin-
drical inside-out construction, cylindrical spiral construction, and user-replaceable
batteries, respectively.
Figure 2.33 shows the load characteristics of the coin-type CR2032. The cell
voltage of the battery is approximately 3 V. Figure 2.34 shows the temperature
characteristics of the CR2032. The battery discharges at a stable voltage over the
◦
wide temperature range of −20 to 70 C.
Figure 2.35 shows the storage characteristics of the cylindrical inside-out
construction CR17335SE. This battery demonstrates extremely good storage
