Dispose of waste batteries in accordance with local laws and regulations. Do
not dispose of batteries as household waste. If a battery is disposed of
improperly, it may explode.
Do not use a damaged battery.
To prevent injuries or explosion, do not allow children or pets to swallow or
bite a battery.
If batteries experience discoloration, deformation, abnormal heating, or other
abnormalities during working, charging, or storage, stop using the batteries
and replace them with new ones.
Batteries can work properly with the allowed charge and discharge
parameters when the temperature is within the specified range. If the
temperature is outside the specified range, the battery charge and discharge
performance and safety are affected.
Install batteries in a dry and cool environment with good ventilation, which is
away from high temperature and flammable materials, and take precautions
against fire.
Place and secure batteries horizontally.
Note the polarities when installing batteries. Do not short-circuit the positive
and negative poles of the same battery or battery string. Otherwise, the
battery may be short-circuited.
When installing a battery string, retain at least one breakpoint to prevent a
loop being formed. After checking that the installation is correct, close the
breakpoints to finish the installation.
During the installation, insulate the terminals of cables connecting batteries.
Ensure that the terminals do not come into contact with metal components
such as the cabinet.
Secure battery cables or copper bars by tightening bolts to the required
torque. Loose connections will result in excessive voltage drop or cause
batteries to burn out in the case of excessive current.
Check battery connections periodically, ensuring that all screws are securely
tightened.
D ANGER
If permitted, disconnect the batteries in use before performing any other
operations on them.
To avoid battery short circuit, do not maintain batteries with power on.
