1.
Battery status indicator (electric eye):
Green: There is sufficient electric quantity in the
battery for starting the vehicle normally.
Black: There is no sufficient electric quantity in
the battery and battery boost charge is needed.
White: The battery is scrapped and it is necessary
to carry out replacement.
2.
Boost charge of Battery
Under the condition of vehicle starting, in the
case of abnormal applications like excessively
long-term operation of electricals, the electric eye
of the battery becomes darkened even the vehicle
fails to start because of the power loss of battery
due to the lack of normal battery charging caused
by long-term parking and vehicle electric leakage
or charging fault in vehicle generator. In this case,
it is necessary to carry out external charging
treatment to the battery.
�
Appearance inspection of the battery prior to
boost charge:
It is not allowed to charge the battery with a
broken case or acid leakage. Please replace the
battery after identifying the cause.
It is not allowed to carry out boost charge for the
battery with a broken terminal post. Please
replace the battery after identifying the cause.
It is not allowed to charge the battery with a
white electric eye. Please replace the battery.
Prior to boost charge, please clean the terminal
post, removing the oxide on the surface.
�
Precautions in charging:
Wear safety goggles.
Maintain ventilation in charging under normal
temperature.
It is not allowed to smoke in charging to prevent
the introduction of fire.
In the wire connection after charging, connect the
positive connecting wire firstly; in the wire
disconnection before charging, disconnect the
negative connecting wire firstly.
�
Battery boost charge:
Confirm that battery terminals are clean and
charging circuit is in good connection.
Connect the positive pole of the charger with that
of the battery while the negative pole of the
charger with that of the battery. Do not charge the
series connected battery (24V).
As dual-purpose charger, one with constant
voltage of 16.0V (maximum permitted voltage
is equal or under 16.2V or large quantity of
water shall be electrolyzed which may lead to
liquid level decrease, white electric eye and
scrapped battery) and rated current of 25 ampere
shall be applied in battery charging until the
electric eye becomes green. The green electric
eye indicates the battery is charged completely.
In the case of no constant voltage charger for
battery
charging,
charge
the
battery
with
constant
current
according
to
following
specifications:
(1)
Select the charging current with rated
capacity of 1/8
~
1/10 ampere for battery
charging and at the end of charging, the
voltage of battery shall reach 16V without
any exceedance (in the case of black electric
eye of the battery with voltage under 16V at
the end of battery charging, there is no
influence to battery application.) When it
can not guaranteed the charging voltage
limit of the charger is under 16V, it is
necessary to monitor the end voltage of
battery to be charged, or there shall be
battery
water
loss
due to
overvoltage
charging even battery failure.
(2)
After charging completion, verify the color
of battery electric eye. In the case of green
electric eye, it indicated that the battery is
charged completely. In the case of black
electric
eye,
verify
whether
charging
connecting wires are connected firmly,
connection points are clean and charging
voltage is 16V. Leave the battery as it is for
24 hours, measure its voltage and carry out
boost charge according to charging interest.
(3)
In the case of white electric eye, it indicates
that there are bubbles in the electric eye and
shake the battery slightly to remove these
bubbles. If the electric eye is still white after
battery shaking (indicating electrolyte loss),
replace the battery.
For battery with voltage lower than 11V, there
may be incapable charging phenomenon at the
beginning of battery charging. The proportion of
sulfuric acid in the battery is close to pure water
and battery internal resistance becomes very
large due to serious battery power loss. In this
case, reduce the charging current or use a
charger with a higher power instead, with the
battery charging goes on, the proportion of
sulfuric acid in the battery increases and the
