radiation, organic solvents, and corrosive gases. Take re prevention
measures.
● Place and secure batteries horizontally.
● Note the polarities when installing batteries. Do not short-circuit the positive
and negative poles of the same battery or battery string. Otherwise, the
battery may be short-circuited.
● Check battery connections periodically, ensuring that all bolts are securely
tightened.
● When installing batteries, do not place installation tools on the batteries.
Battery Short Circuit
Battery short circuits can generate high instantaneous current and release a great
amount of energy, which may cause equipment damage or personal injury.
To avoid battery short-circuit, do not maintain batteries with power on.
Flammable Gas
● 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
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.
