Stable Operating Voltage of 3V
Lithium batteries have a high discharge voltage of 3 volts. Thus
a single lithium battery can be used to replace two or three
conventional silver oxide or manganese batteries (1.5V). The
stable operating voltage over as long as 10 years, at room
temperature, ensures outstanding performance, quality and
reliability.

Nominal Voltage of Major Batteries
More Than 95% of Initial Capacity Even After 10 Years
A stable electrolyte, Sanyo's superior manufacturing methods
and sealing technology combine to ensure that the tendency of
lithium batteries to self-discharge is reduced to a very low level.
Even after 10 years of storage at room temperature, more than
95% capacity is retained.
Self-discharge rate per year at room temperature:
Coin type primary battery:
under 1%
High-power cylindrical type primary battery:
Crimp-sealing
under 1%
Laser-sealing
under 0.5%
High-capacity cylindrical type primary battery:

Operational Temperature Range
Sanyo lithium batteries have an organic electrolyte with a very
low freezing point, which guarantees reliable operation even at
extremely low temperatures.
Additionally, rigorous selection of materials and superior sealing
technology give these batteries excellent characteristics even at
high temperatures.

Superior Leakage Resistance
The use of an organic solvent rather than an alkali for the
electrolyte significantly minimizes leakage. Futhermore, laser
sealing technology also minimizes the risk of electrolyte
leakage.
Greater Safety
(UL approved)
Since Sanyo primary lithium batteries do not contain toxic
materials, noxious liquids or gases, they pose no major polution
problems. They are UL recognized components (File No.
MH12383).
