Battery Installation 
Before installing batteries, observe the following safety precautions: 
 
Install batteries in a well-ventilated, dry, and cool environment that is far away from heat 
sources, flammable materials, moistures, extensive infrared radiation, organic solvents, 
and corrosive gases. Take fire 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 fire or corrosion, ensure that flammable gas (such as hydrogen) is properly 
exhausted for lead-acid batteries. 
Lead-acid batteries emit flammable gas when used. Ensure that batteries are kept in a 
well-ventilated area and take preventive measures against fire. 
Battery Leakage 
 
 
Battery overheating causes deformation, damage, and electrolyte spillage.
