Before operating batteries, carefully read the safety precautions to ensure correct battery
handling and connection is performed, and personal safety is managed.
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.
