Battery overheating causes deformation, damage, and electrolyte spillage.
When the electrolyte overflows, 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 overflow may damage the equipment. It will corrode metal parts and boards,
and ultimately damage the boards.
If the electrolyte overflows, 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.
Do not throw a lithium battery in fire.
When maintenance is complete, return the waste lithium battery to the maintenance
office.
