1.6 Battery Safety
If no battery is involved, skip this section.
Before installing, operating, or maintaining batteries, read the battery manufacturer's
instructions. The safety precautions specified in this document are highly important
precautions that require special attention. For additional safety precautions, see the
instructions provided by the battery manufacturer.
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.
When replacing a battery, use a battery of the same model or type. Improper replacement
may cause the battery to explode.
Do not connect a metal conductor to the battery poles or touch the battery terminals.
Otherwise, the battery may be short-circuited and heat up, which can cause injuries such as
burning.
To ensure safety during battery installation, operation, and maintenance, pay attention to the
following:
Do not wear conductive articles such as watches, bracelets, bangles, and rings.
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.
Do not drop, squeeze, or puncture a battery. Protect batteries from external high pressure
to prevent internal short circuits and overheating.
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.
