1.2.2 Battery Safety
D ANGER
Do not connect the positive and negative poles of a battery or battery string
together. Otherwise, the battery may be short-circuited. Battery short circuits can
generate high instantaneous current and releases a large amount of energy, which
may cause battery leakage, smoke, ammable gas release, thermal runaway, re,
or explosion. To avoid battery short circuits, do not maintain batteries with power
on.
D ANGER
Do not expose batteries at high temperatures or around heat sources, such as
scorching sunlight, re sources, transformers, and heaters. Battery overheating
may cause leakage, smoke, ammable gas release, thermal runaway, re, or
explosion.

stay away from the battery and contact professionals immediately. Professionals
shall wear safety goggles, rubber gloves, gas masks, and protective clothing,
power o the equipment, remove the battery, and contact technical engineers.
D ANGER
A battery is an enclosed system and will not release any gases under normal
operations. If a battery is used improperly, for example, burnt, needle-pricked,
squeezed, struck by lightning, overcharged, or subject to other adverse conditions
that may cause battery thermal runaway, the battery may be damaged or an
abnormal chemical reaction may occur inside the battery, resulting in electrolyte
leakage or release of gases such as CO and H2. To prevent re or equipment
corrosion, ensure that ammable gases are properly exhausted.
D ANGER
The gases generated by a burning battery may irritate your eyes, skin, and throat.
