I. There is a risk of
fire and explosion, open fire or electric spark shall not be allowed near the
battery.
II. Never confuse the
positive and negative terminals of the battery, otherwise spark and explosion
will occur.
III. The battery
electrolyte contains highly corrosive sulfuric acid. When maintaining the
battery, wear an acid-proof apron and a top cover or protective goggles. When
adding electrolyte to the battery, be careful to add it slowly and prevent liquid
splashing. Once the electrolyte accidentally splashed on the skin or clothing,
immediately rinse with plenty of water.
Battery
connection and disconnection
I. First connect the red
wire (+) to the battery (+) pole. Then connect the black wire (-) to the
battery (-) pole.
II. When disconnecting
the battery, first remove the (-) wire (black), then remove the (+) wire (red).
Battery
cleaning
Keep the battery dry and
clean. Oxides and dirt on batteries and terminals can cause short circuits,
voltage drops and discharges, especially in wet weather. Clean battery
terminals and cables with brass brush to to remove oxides. Tighten the cable
connector and apply protective grease or Vaseline to the joint.
Introduction
to battery charging
I. The battery is dry when
it is delivered to the user. Therefore, the electrolyte with the correct
specific gravity (>1.5) that has been uniformly mixed should be added before
use. Unscrew the top cover of the battery and slowly inject the electrolyte
until it is between the two scale lines on the upper part of the metal sheet
and as close as possible to the upper scale line. After adding it, please do
not use it immediately. You should let the battery park for about 15 minutes.
You can also connect the charger to charge it to the right amount.
II. When charging the
battery for the first time, it should be noted that the continuous charging
time should not exceed 4 hours. Because too long charging time will damage the
service life of the battery.
III. When one of the
following conditions occurs, the charging time is allowed to be extended
appropriately:
a. Battery storage time
is more than 3 months, charging time can be 8 hours.
b. The ambient
temperature continues to exceed 30°C or the relative humidity continues to be
higher than 80%, and the charging time can be 8 hours.
c. If the battery is
stored for more than 1 year, the charging time can be 12 hours.
d. If the charger
current output is insufficient, the low current charging time should be
extended proportionally.
e. At the end of
charging, check whether the liquid level of the electrolyte is sufficient, and
add standard electrolyte with the correct specific gravity if necessary.
f. It should be noted
that the size of the charging current and the length of the charging time
should also take into account the old and new conditions of the battery and the
amount of power already stored in the battery. When charging the battery, first
open the battery filter cap or vent cap and check the electrolyte level and
adjust with distilled water if necessary.
g. Normal operation and
charging can cause some water to evaporate, which requires refilling the
battery at any time. Firstly, the battery surface, especially the filling port,
is thoroughly cleaned to prevent dirt from entering the battery compartment,
then remove the hole plug, and distilled water is added until the appropriate
liquid level.
h. In order to prevent
long-term closure, the sewage in the battery compartment cannot be discharged
in time, and the water droplets are prevented from condensing on the inner top
wall of the cell.
i. It is necessary to
open a special vent hole to facilitate proper air circulation. Make sure the
battery is charged in a well-ventilated environment with no sparks or open
flames nearby. Do not charge in an environment that cannot be protected from
snow, and the charger should not be near water.
