PRECAUTIONS FOR DESIGNING DEVICES WITH NI-CD BATTERIES
In order to take full advantage of the properties of Ni-
Cd batteries and also to prevent problems due to
improper use, please note the following points during
the use and design of battery operated products.
1. Charging
1.1 Charging temperature
•
•
•
•
1.2 Parallel charging of batteries
•
1.3 Reverse charging
•
1.4 Overcharging
•
Charge batteries within an ambient temperature
range of 0°C to 45°C.
Ambient temperature during charging affects
charging efficiency. As charging efficiency is best
within a temperature range of 10°C to 30°C,
whenever possible place the charger (battery
pack) in a location within this temperature range.
At temperatures below 0°C the gas absorption
reaction is not adequate, causing gas pressure
inside the battery to rise, which can activate the
safety vent and lead to leakage of alkaline gas
and deterioration in battery performance.
Charging efficiency drops at temperatures above
40°C. This can disrupt full charging and lead to
deterioration in performance and battery leakage.
Sufficient care must be taken during the design
of the charger when charging batteries con-
nected in parallel.
Consult Panasonic when parallel charging is
required.
Never attempt reverse charging.
Charging with polarity reversed can cause a
reversal in battery polarity causing gas pressure
inside the battery to rise, which can activate the
safety vent, lead to alkaline electrolyte leakage,
rapid deterioration in battery performance,
battery swelling or battery rupture.
Avoid overcharging. Repeated overcharging can
lead to deterioration in battery performance.
(“Overcharging” means charging a battery when
it is already fully charged.)

1.5 Rapid Charging
•
1.6 Trickle charging (continuous charging)
•
•
2. Discharging
2.1 Discharge temperature
•
•
•
2.2 Overdischarge
•
2.3 High-current discharging
•
To charge batteries rapidly, use the specified
charger (or charging method recommended by
Panasonic) and follow the correct procedures.
Carry out trickle charge by applying the current
of 0.02 to 0.05 CmA. The correct current value
is determined depending on the features and
purpose of the equipment.
Note : “CmA”
During charging and discharging, CmA is a
value indicating current and expressed as a
multiple of nominal capacity. Substitute “C” with
the battery’s nominal capacity when calculating.
For example, for a l500mAh battery of
0.033CmA, this value is equal to 1/30 × 1500, or
roughly 50mA.
Discharge batteries within an ambient tempera-
ture range of -20°C to +65°C.
Discharge current level (i.e. the current at
which a battery is discharged) affects discharg-
ing efficiency. Discharging efficiency is good
within a current range of 0.1 CmA to 0.5 CmA.
Discharge capacity drops at temperatures
below -20°C or above +65°C. Such decreases
in discharge capacity can lead to deterioration in
battery performance.
Since overdischarging damages the battery
characteristics, do not forget to turn off the
switch when discharging, and do not leave the
battery connected to the equipment for long
periods of time. Also, avoid shipping the battery
installed in the equipment.
As high-current discharging can lead to heat
generation and decreased discharging effi-
ciency, consult Panasonic before attempting
continuous discharging or pulse discharging at
currents larger than 2 CmA.
