d) Discharge current
Discharge capability of batteries is expressed by the
20 hour rate (rated capacity). Select the battery for
specific equipment so that the discharge current
during use of the equipment falls within the range
between 1/20 of the 20 hour rate value and 3 times
that (1/20 CA to 3 CA): discharging beyond this range
may result in a marked decrease of discharge ca-
pacity or reduction in the number of times of repeat-
able discharge. When discharging the battery beyond
said range, please consult Panasonic in advance.

e) Depth of discharge
Depth of discharge is the state of discharge of
batteries expressed by the ratio of amount of capac-
ity discharged to the rated capacity.

Storage
a) Storage condition
Observe the following condition when the battery
needs to be stored.
Observe the following condition when the battery
needs to be stored.
(1) Ambient temperature: 5°F to 104°F (-15°C to
40°C) (preferably below 86°F (30°C))
(2) Relative humidity: 25 to 85%
(3) Storage place free from vibration, dust, direct
(3) Storage place free from vibration, dust, direct
sunlight, and moisture.
b) Self discharge and refresh charge
During storage, batteries gradually lose their capacity
due to self discharge, therefore the capacity after
storage is lower than the initial capacity. For the
recovery of capacity, repeat charge/discharge sev-
eral times for the battery in cycle use; for the battery
in trickle use, continue charging the battery as loaded
in the equipment for 48 to 72 hours.

When it is unavoidable to store the battery for 3
months or longer, periodically recharge the battery at
the intervals recommended in the table below de-
pending on ambient temperature. Avoid storing the
battery for more than 12 months.

d) Residual capacity after storage
The result of testing the residual capacity of the
battery which, after fully charged, has been left
standing in the open- circuit state for a specific period
at a specific ambient temperature is shown in the
figure below. The self discharge rate is very much
dependent on the ambient temperature of storage.
The higher the ambient temperature, the less the
residual capacity after storage for a specific period.
The self discharge rate almost doubles by each 10°C
rise of storage temperature.
