Flammable Gas
NO TICE
● Do not use unsealed lead-acid batteries.
● To prevent re or corrosion, ensure that ammable gas (such as hydrogen) is
properly exhausted for lead-acid batteries.
Lead-acid batteries emit ammable gas when used. Ensure that batteries are kept
in a well-ventilated area and take preventive measures against
re.
Battery Leakage
NO TICE
Battery overheating causes deformation, damage, and electrolyte overow.
If the battery temperature is higher than 60°C, check the battery for electrolyte
overow. If the electrolyte overows, handle the leakage immediately.
Electrolyte overow may damage the equipment. It will corrode metal parts and
boards, and ultimately damage the boards.
WARNING
When the electrolyte overows, absorb and neutralize the electrolyte immediately.
When moving or handling a battery whose electrolyte leaks, note that the leaking
electrolyte may cause damage.
If the electrolyte overows, follow the instructions of the battery manufacturer or
neutralize the electrolyte by using sodium bicarbonate (NaHCO
3
) or sodium
carbonate (Na
2
CO
3
).
Lithium Battery
The safety precautions for lithium batteries are similar to those for lead-acid
batteries except that you also need to observe the following precautions.
WARNING
There is a risk of explosion if the model of the replaced battery is incorrect.
● A battery can be replaced only with a battery of the same or similar model
recommended by the manufacturer.
● When handling a lithium battery, do not place it upside down, tilt it, or bump
it with other objects.
