Safety Precautions for Using Ni-Cd Battery
Storage
• Please remove the Ni-Cd batteries from the main unit when storing.
• Do not leave the batteries in a hot-temperature environment such as under direct sun
light, inside an automobile, or near fire, because this leads to leakage of the alkaline
electrolyte.
• For long-term storage (6 months to 2 years), select a location where the humidity is
low and the temperature is in the range from 10 to 25
°
C.
• When charging for the first time after long-term storage, deactivation of the reactants
may have led to decreased battery capacity, but this problem is restored after several
cycles of charging and discharging.
• When storing the batteries for more than 6 months, please charge or discharge then
recharge the batteries at least once per year to prevent leakage and the decline of
performance.
Battery Life
The time of operation of the batteries gradually decreases with repeated use, even when
the batteries are fully charged. Though it depends on the condition of use, take 2 years
or 500 times as a measure to have the batteries replaced. (A typical battery life is 2
years or 500 times.) Please also note that prolonged storage leads to shortened battery
life.
Charging
• Do not charge the batteries in any other instrument.
• Only charge batteries that are completely discharged. Charging batteries that are
partially charged results in overcharging. This shortens battery life.
• Avoid overcharging the batteries, because this leads to shortened battery life.
• Charging the batteries for a long time may cause leakage of gases and electrolytes.
WARNING
• Do not disassemble or alter the batteries in any way.
The electrolyte inside the batteries is strong alkaline which can
damage skin and clothes. Be especially careful of the electrolyte
entering the eye, because it may cause blindness.
• Never short the batteries. Heat generated by the batteries may
cause burns.
• Never heat or throw the batteries into fire. The batteries can
rupture or the electrolyte may spray out.
• Never put water on the batteries or immerse them in water.
Such actions can cause heat to be generated or lead to rusting
as well as the loss of ability to function.
• Do not use the batteries in any other instrument. The difference
in the specification can cause damage to the other instrument.
• Do not pull the cable of Ni-Cd battery back or connector with
excessive force.
