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
Battery overheating causes deformation, damage, and electrolyte spillage.
When the electrolyte overows, absorb and neutralize the electrolyte immediately.
When moving or handling a battery whose electrolyte leaks, note that the leaking
electrolyte may hurt human bodies.
● If the battery temperature exceeds 60°C, check for and promptly handle any
leakage.
● Electrolyte overow may damage the equipment. It will corrode metal parts
and boards, and ultimately damage the boards.
● If the electrolyte
overows, 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 note the precautions described in this
section.
There is a risk of explosion if a battery is replaced with an incorrect model.
● 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.
● Keep the lithium battery loop disconnected during installation and
maintenance.
● Do not charge a battery when the ambient temperature is below the lower
limit of the operating temperature (charging is forbidden at 0°C). Low-
temperature charging may cause crystallization, which will result in a short
circuit inside the battery.
● Use batteries within the allowed temperature range; otherwise, the battery
performance and safety will be compromised.
