charging current for battery can return to normal
gradually.
In the process of charging, if there is a large
quantity of acid spraying out from battery vent,
stop charging and identify the cause.
In the process of charging, when the battery
temperature exceeds 45 ℃ , stop charging. When
the battery is cooled down to room temperature,
go on to charge it with half charging current.
In the process of battery boost charge, check the
status of electric eye once an hour. In the case of
green electric eye, it indicates that the battery is
charged completely and stop charging.
After charging completion and relevant test, it is
recommended to apply grease on battery
terminals to avoid electrolytic corrosion.
3. Correct Application of Battery
� The discharging time of battery in large current
should not be too long or pole plate shall be
deformed due to overheating that may lead to
short circuit or battery capacity reduction caused
by active material shedding. In the case of vehicle
start, each start time should not exceed 5 seconds
and the interval between continuous starts should
not less than 10~15 seconds;
� In capacity inspection with high rate discharging
gauge (discharging meter), the discharging time
should not exceed 5 seconds;
� In normal vehicle running, battery is in charging
state generally; In the case of low power supply
capacity of generator due to improper regulation
of regulator, excessive battery power
consumption due to frequent vehicle start or
serious battery power loss due to short circuit in
electric appliance, it is necessary to carry out
battery boost charge.
� After 3 months of battery service time, when the
battery capacity is lower than 50% or
phenomenons like underpowered vehicle starting,
dim lighting, abnormal honk etc., off-board boost
charge for battery shall be carried out as well as
normal maintenance. At the same time, pay
attention to batteries in the process of charging
for batteries with the same capacity and different
voltages shall not be charged together. It is not
allowed the mixed use of new and old batteries.
� The output voltage of vehicle voltage regulator
shall be measured after battery loading and shall
be regulated in the range of 13.8~14.8 V
according to vehicle service condition. The
recommended voltage is 14.4V. In the case of
frequent vehicle application, it is easy to cause
battery overcharge and the voltage should be
regulated to a lower one. On the contrary, in the
case of infrequent vehicle application or frequent
vehicle start, the voltage should be regulated to a
higher one. To avoid overcharge, the voltage
should be heightened while in summer it should
be lowered.
� In the case of long-term parking, the negative
terminal should be disconnected with vehicle to
avoid excessive self discharge and serious
sulfating. Under the condition of no battery
power loss, recharge the maintenance-free battery
once every 3 months. In the case of instant power
loss at the beginning of parking, it is necessary to
recharge the battery timely according to the
voltage. In general, when battery voltage is under
12.6V, it is necessary to recharge the battery.
It is not allowed for the battery discharging current to
exceed that of the maximum battery of the
manufacturer. In general, the discharging current is
4~5 times as large as that of 4 ～ 5C20 battery capacity.
It is not allows to test battery electrification with
short-circuit method.
