User's Manual

Where the SOC and SOH indicates the State of Charge and State of
Health respectively.
There are mainly 5 states as follows:
No. States Descriptions
1 Good battery Indicates the battery is normal.
2 Replace battery
Indicates that the battery is aged or
becomes rejected, or battery life cycle
approaches to be exhausted. In this
case, battery voltage appears to be
normal, but battery itself is not well,
i.e. battery polarity board has been
completely vulcanized or aged. Please
replace battery immediately.
3 Good-recharge
The tested battery is good itself, but
has a low voltage. Please recharge it
before use.
4 Charge-retest
It is better for a few batteries to be
fully charged before testing in order
to avoid judging in error under special
conditions.
5 Bad cell
Indicates one of the battery cells is
bad and can not work normally, but for
which one is bad, it can’t be verifi ed. In
this case, battery voltage is generally
lower than 11V, mainly resulting from
internal circuitry damage, such as short
circuit, open circuit, dummy weld etc.
If the voltage is lower than 11V for the
bad cell battery, it is possible that the
battery is completely exhausted or has
a serious low capacity. In this case, just
recharge your battery. Bad cell always
happens when the loads on a stopping
vehicle are turned on for a long time.
7.2.3 Start System Test
This function is desgined to test and analyze the starting motor.
Through testing the actual required cranking current and voltage of the
starting motor, it can be found out that the whether the starting motor
is normal or not.
The starting motor is not normal, which may be caused by the
following reasons: the malfunctioning of the lubrication system
increases the starting load torque; the rotor friction of the starting
motor causes the starting motor to increase its friction.
