To ensure battery safety and efficient battery management, use the batteries delivered with
the UPS. Huawei shall not be responsible for battery damage caused by using non-Huawei
batteries for Huawei UPSs.
Ensure lead-acid battery handling is in accordance with local regulations.
Incorrect handling of batteries may cause hazards. When operating batteries, avoid
battery short circuits and electrolyte overflow or leakage.
Electrolyte overflow may damage the device by corroding metal parts and circuit boards,
and ultimately damaging the circuit boards.
Short circuits caused by incorrect operations may cause serious injuries due to high
power of batteries.
Do not reversely connect positive and negative battery terminals.
Use batteries of the specified type. Otherwise, the batteries may be damaged.
Check battery connections periodically to ensure that all screws are securely tightened.
Install or store batteries in clean, cool, and dry environments.
Do not decompose, transform, or damage batteries. Otherwise, battery short circuit,
electrolyte leakage, and even personal injury may occur.
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.
Battery 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.
