2.
Run the
power battery-test
command to configure the parameters for the automatic
discharge test, such as the test interval, start time, test duration, and end-of-charge
voltage.
3.
Run the
display power battery-test info
command to query the discharge test
information about the batteries.
Determine whether the batteries are working properly based on the discharge test
information.
–
If the actual end-of-charge voltage is larger than the preset value when the
discharge duration is equal to the preset value, the batteries are working properly.
–
If the actual end-of-charge voltage is equal to the preset value when the actual
discharge duration is less than the preset value, the battery capacity is attenuated.
Maintain or replace the batteries on site.

Follow-up Procedure
l
If the shells of the batteries are not clean, clean the batteries immediately.
l
If the shells of the batteries are leaking or distorted, replace the batteries immediately.
l
If the battery terminals are bent or damaged, replace the batteries immediately.
l
If the spacing between the batteries is less than 10 mm, adjust the spacing properly.
l
If the joints between the batteries are loose or corroded, fix or replace them based on site
requirements.
l
If the operating temperature of the batteries is lower than -20°C or higher than 50°C, identify
the cause and rectify the fault.
NOTE
The operating temperature has a significant impact on the life cycle of the batteries. The life cycle
of a battery reduces by half for every 10°C increase in temperature when the battery is operating
outside the acceptable range.
l
If the floating charge voltage is abnormal, replace the batteries.
l
If the fault persists, contact Huawei technical support. For details on how to contact Huawei
technical support, see

2.5 Checking the surge protector
It is recommended that you protect the lightning proof system and the power system against the
thunder and storms before the raining season. This operation ensures the reliable running of the
device and prevents the potential security disasters that may exist in the system.
Context
CAUTION
Before the raining season, protect the lightning proof system and the power system against the
thunder and storms. Prevent the body injury and the short circuit when maintaining the device.
