1.7 Battery Safety
Basic Requirements
Before operating batteries, carefully read the safety precautions for battery handling and
master the correct battery connection methods.
Do not expose batteries at high temperatures or around heat-generating devices, such as
sunlight, fire sources, transformers, and heaters. Excessive heat exposure may cause the
batteries to explode.
Do not burn batteries. Otherwise, the batteries may explode.
To avoid leakage, overheating, fire, or explosions, do not disassemble, alter, or damage
batteries, for example, insert sundries into batteries or immerse batteries in water or other
liquids.
Wear goggles, rubber gloves, and protective clothing to prevent skin contact with
electrolyte in the case of electrolyte overflow. If a battery leaks, protect the skin or eyes
from the leaking liquid. If the skin or eyes come in contact with the leaking liquid, wash
it immediately with clean water and go to the hospital for medical treatment.
Use dedicated insulated tools.
Move batteries in the required direction. Do not place a battery upside down or tilt it.
Keep the battery loop disconnected during installation and maintenance.
Use batteries of specified models. Using batteries of other models may damage the
batteries.
Dispose of waste batteries in accordance with local laws and regulations. Do not dispose
of batteries as household waste. If a battery is disposed of improperly, it may explode.
