WARNING
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

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.
