Battery Leakage
Battery overheating causes deformation, damage, and electrolyte overflow.
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 cause damage.

WARNING
When the battery temperature exceeds 60°C, check whether the electrolyte
overflows. If the electrolyte overflows, handle the leakage immediately.
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 use sodium bicarbonate (NaHCO
(Na
CO
) to neutralize the electrolyte.

WARNING
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.
