Preventative Measures
When installing and maintaining batteries, pay attention to the following points:
Use dedicated insulated tools.
Take measures to protect eyes, such as using eye protection devices.
Avoid skin contact with electrolyte overflow. Wear rubber gloves and protective
clothing.
When handling a battery, ensure that its electrodes always point upward. Do not tilt or
overturn batteries.
Switch off the power supply during installation and maintenance.
Short Circuit
Battery short circuits may cause personal injury. The high transient current generated by a
short circuit may release a surge of power and cause a fire.
To avoid battery short circuits, do not maintain batteries while they are in use.
Harmful Gas
Do not use unsealed lead-acid batteries. Lead-acid batteries emit flammable gas. Therefore,
place and secure lead-acid batteries horizontally to prevent fire or corrosion.
Store lead-acid batteries in a place with good ventilation, and take fire safety precautions.
Battery Temperature
High temperature may result in battery distortion, damage, and electrolyte overflow.
Install or store batteries far away from fire sources and heating devices such as
transformers. Never burn batteries.
If the battery temperature exceeds 60°C, check the battery for electrolyte overflow. If
electrolyte overflows, handle the leakage immediately.
