PRECAUTIONS FOR DESIGNING DEVICES WITH NI-CD BATTERIES-(CONT.)
3. Storage
3.1 Storage temperature and humidity (short-term)
3.2 Long-term storage (2 year, -20°C to +35°C)
4. Service Life of Batteries
4.1 Cycle life
Store batteries in a dry location with low humidity,
no corrosive gases, and at a temperature range
of -20°C to +45°C.
Storing batteries in a location where humidity is
extremely high or where temperatures fall below
-20°C or rise above +45°C can lead to the
rusting of metallic parts and battery leakage due
to expansion or contraction in parts composed of
organic materials.
Because long-term storage can accelerate
battery self-discharge and lead to the deactiva-
tion of reactants, locations where the tempera-
ture ranges between +10°C and +30°C are
suitable for long-term storage.
When charging for the first time after long-term
storage, deactivation of reactants may lead to
increased battery voltage and decreased battery
capacity. Restore such batteries to original
performance by repeating several cycles of
charging and discharging.
When storing batteries for more than 1 year,
charge at least once a year to prevent leakage
and deterioration in performance due to self-
discharging. When using a rapid voltage detec-
tion type battery charger carry out charge and
discharge at least once every 6 months.
Batteries used under proper conditions of charg-
ing and discharging can be used 500 cycles or
more.
Significantly reduced service time in spite of
proper charging means that the life of the battery
has been exceeded.
Also, at the end of service life, an unusual in-
crease in internal resistance, or an internal short-
circuit failure may occur. Chargers and charging
circuits should therefore be designed to ensure
safety in the event of heat generated upon battery
failure at the end of service life.
Please contact Panasonic if you have any ques-
tions.

Because batteries are chemical products involv-
ing internal chemical reactions, performance
deteriorates not only with use but also during
prolonged storage.
Normally, a battery will last 3 to 5 years if used
under proper conditions and not overcharged or
overdischarged.
However, failure to satisfy conditions concerning
charging, discharging, temperature and other
factors during actual use can lead to shortened
life (or cycle life) damage to products and dete-
rioration in performance due to leakage and
shortened service life.
Never solder a lead wire and other connecting
materials directly to the battery, as doing so will
damage the battery’s internal safety vent, separa-
tor, and other parts made of organic materials.
To connect a battery to a product, spot-weld a tab
made of nickel or nickel-plated steel to the
battery’s terminal strip, then solder a lead wire to
the tab.
Perform soldering in as short a time as possible.
Use caution in applying pressure to the terminals
in cases where the battery pack can be sepa-
rated from the equipment.
When rapid charging using the voltage detection
method with a large current (1It or more), or when
leaving the battery installed in the equipment, be
sure to follow connecting the precaution listed
above. Even for other uses, if connecting the
precaution listed above is used as much as
possible, contact defects in the connection
process can be reduced.
batteries
Because small amounts of alkaline electrolyte
can leak out from the battery seal during extended
use or when the safety vent is activated during
improper use, use a highly alkaline-resistant
material for a product’s contact terminals in order
to avoid problems due to corrosion.
