Short Circuit
Battery short circuits may cause human injuries. Although the voltage of ordinary batteries is
low, the instantaneous high current caused by the short circuit releases a great deal of energy.
To avoid battery short circuits, do not maintain batteries in use.
Harmful Gas
Do not use unsealed lead-acid batteries. Place and secure lead-acid batteries horizontally to
avoid inflammation or device corrosion due to flammable gases emitted from batteries.
The lead-acid batteries in use may emit flammable gases. Therefore, store the batteries in a
place with good ventilation, and take precautions against fire.
Battery Temperature
High temperature may result in battery distortion, damage, and electrolyte overflow.
