4. CHARGER AND BATTERY
4-1. Precautions for Handling
Mishandling of the charger and battery may cause a liquid leak, ignition, trouble or injury.
Prior to using them, read the following precautions carefully.
- Store them beyond child’s reach.
- Check the polarity of the battery to connect it.
- Never short-circuit the battery.
(If the battery is stored together with a metal or a conductive substance, it may be damaged by the
conductive substance due to certain disturbance, resulting in short-circuit. When carrying them together,
put the battery in a separate case.)
- Do not wet or put the battery in water or sea water.
- Do not use or store the battery in a high-temperature, high-humidity place.
- Do not leave the battery for a long time, connected to the robot.
After using, be sure to turn off the switch of the robot.
- If the battery is not used, remove it from the robot and store it in a place with normal temperature (0 to
30ºC) and low humidity.
- Charge the battery at its temperature of 0 to 40ºC. It is dangerous if the temperature exceeds 40ºC. Cool
the battery with a cooling device.
- If you notice abnormal heat generation, foul smell or smoke while charging, stop charging
immediately.
- If you notice abnormal heat generation, foul smell or smoke while using the battery, turn off the
switch immediately and remove the battery from the robot.
- If you notice a liquid leak from the battery or its discoloration, deformation, foul smell or other
abnormality, do not use it.
- If the battery cannot be fully charged after the specified charging time, stop charging.
- After charging is completed, disconnect the battery immediately from the charger.
- Do not throw the battery into fire, heat it or deform it.
- Do not disassemble or remodel the battery.
- Do not peel off or damage the coating tube of the battery.
- Do no remodel a connector, etc.
- Use the charger only for the purpose of charging.
- Never use the charger as a DC power source.
- If the battery liquid gets into the eye, rinse it fully with clean tap water immediately and consult a medical
doctor.
- If the battery liquid adheres to the skin or clothing, rinse them fully with clean tap water immediately.
- The battery is basically accompanied by danger. As it could lead to a fire, do not leave it while it
is charged.
- Do not connect the fully charged battery to the charger.
- The nickel metal hydride battery may be out of service as a battery, once the voltage of each cell
is 1 V or less (5 V or less for this battery because it has 5 cells).
If it is charged in this condition, it may be damaged.
The battery voltage may drop to 5 V or less momentarily while it is operating, but it is no problem, just a
voltage drop due to the running current.
