OPERATION & MAINTENANCE MANUAL STE35SR
Additional Electric Battery
Before cars started, the car with electric start time is too long and abnormal use, because of
leakage and long car stops, the vehicle or the vehicle charging generator failure, the battery can't
normal charging battery loss caused by electricity, battery electric eye blackened, even can't start
the car. The battery need to supplement by electricity.
Check the battery status indicator (wink), power display:
Green: the battery power is enough, can normal boot excavator.
Black: deficiency of battery, the battery should be added.
White: battery needs replacement.
1. nce inspection before charging
Do not charge the battery if the shell burst or it leaks acid, replace the battery after finding
out the reason.
Do not charge the battery if its end column burst, replace the battery after finding out the
reason.
Do not charge the battery if the electric eye is white and replace the battery
Do not charge the inflation bulging battery caused by over-discharge or overcharge and
replace the battery
Clean the end column and remove the surface scale before charge the battery.
2. When charging the battery we must know
Wearing glasses.
Maintain environmental ventilation when charging, charging under normal temperature.
No smoking when charging, and avoid the introduction of the flame.
After charging connection, first connect the positive attachment; Take out stitches before
charging, disconnect the cathode attachment first.
3. Battery charging
Connect the positive (+) charger clip of the charger to the positive (+) terminal of the
battery, then connect the negative (-) charger clip of the charger to the negative (-)
terminal of the battery.
Make sure the battery is clean and the charging circuit is well connected.
Recommended use constant voltage 16.0 volts (maximum can not exceed 16.2 volts, the
charging current does not exceed 25A) charger to charge battery until the electric eye
turns green. The battery is fully charged when the eye turns green.
IF there is not a constant voltage way to charge, according to the following specifications
constant current charging:
Charging current(A)=C20/10. (C20 --- 20 hours rate capacity)
Note: If more than one battery is charged in parallel, the current values are summed.
Charging time and battery voltage corresponding relationship (reference)
After charging, check the color of the accumulator's eye. The electro-optic display is
green, indicating that the battery is fully charged. If the eye is black, check whether the
charging connection is secured, whether the connection point is clean, and continue to
replenish the electricity until the eye appears green. For batteries whose battery voltage
is less than 11.0V, the phenomenon of battery charging out may occur in the initial stage
of replenishment. Because of the serious shortage of batteries, the proportion of sulfuric
acid in the batteries has approached pure water, and the internal resistance of the
batteries is very large. With the charging of the batteries, the proportion of sulfuric acid in
