CHARACTERISTICS - CONTINUED
e) Open circuit voltage vs. residual capacity
Residual capacity of the battery can be roughly
estimated by measuring the open circuit voltage as
shown in the Figure.
Open circuit voltage vs. Residual capacity 77°F (25°C)

Temperature conditions
Recommended temperature ranges for charging,
discharging and storing the battery are tabulated
below.

Battery life
a) Cycle life
Cycle life (number of cycles) of the battery is depen-
dent on the depth of discharge in each cycle. The
deeper the discharge is, the shorter the cycle life
(smaller number of cycles), providing the same
discharge current. The cycle life (number of cycles)
of the battery is also related to such factors as the
type of the battery, charge method, ambient tempera-
ture, and rest period between charge and discharge.
Typical cycle-life characteristics of the battery by
different charge/discharge conditions are shown by
the chart to the right.
This data is typical and tested at a well-equipped
laboratory in a controlled environment.
Cycle times are different for each battery model.
Cycle times can also differ from this data when using
batteries under real conditions.
