– If the battery is found to have abnormal me-
chanical characteristics such as swelling,
cracked casing, melted casing, and distor-
tion of the casing before and during instal-
lation, stop using the battery immediately,
place it in open and well-ventilated space,
and contact the after-sales service.
– If abnormalities such as looseness, cracks,
cracks in the insulation layer, burn marks,
etc. of the battery's pole pressing bolts,
conductive strips, main circuit wires and
connectors are found before and during the
installation, stop using the battery immedi-
ately, contact the after-sales service.
– If the polarity of the positive and negative
terminals of the battery is found not match
the polarity identification before installation,
please stop using the battery immediately
and contact the aftersales service depart-
ment to replace the battery or obtain other
solutions.
– If there is fire or smoke happens to the bat-

Maintenance
Daily Maintenance
– It is necessary to arrange professionals for
care during the charging operation, espe-
cially when the battery is almost fully charg-
ed; make sure that the plug and the sock-
et are in good contact during the charging
process to ensure the normal work of the
charging device and good contact of the
connection points of the battery pack. If an
abnormality occurs, the battery needs to be
repaired before charging.
– Check the battery voltage, temperature,
voltage difference, etc. displayed on the cir-
cular display meter before charging and dis-
charging to ensure that all values are within
the normal range.
– If there is a large amount of dust, metal
shavings or other debris on the upper cov-
er and poles of the battery pack, use com-
pressed air or wet cloth to clean it in time,
avoid cleaning with water or water-soaked
objects.
– When charging and discharging, try to avoid
water or other conductive liquids splashing
on the top cover and poles of the battery,
such as rainwater.
– Estimate the charging time and discharging
time of the battery according to the actual
status of use of the battery or battery pack,
observe whether there is any abnormality
in the battery or battery pack at the end of
charging and the end of discharging, such
as the voltage difference of the battery.
Regular Maintenance
– Check the nodes such as the conductive
strips and voltage collection terminals for
looseness, shedding, rusting or deforma-
tion, etc., to ensure that the series-parallel
harness used in the battery pack is firm and
reliable (once a month).
– Check the battery casing for cracks, defor-
mation, loose poles, bulging and other ab-
normal conditions (once a month).
– Check the reliability of the charging device
to ensure that the charging device performs
the charging action in accordance with the
voltage and current adjustment signals sent
