LAUNCH Battery 5001 User Manual
test report (see Fig. 5-7).
1. Good battery - Indicates that the battery is normal.
2. Replace battery - Indicates that the battery is aged or becomes rejected, or
battery life cycle is nearly 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 - Stands for low battery. The battery is good itself.
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 cannot work normally,
but for which one is bad, it can’t be veried. 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.
5.1.3 Start System Test
It is mainly to detect and analyze the starting motor, detect the actual starting
current and starting voltage required by the starting motor, so as to judge
whether the starting motor is normal or not. The abnormal starting motor may
be caused by the following reasons: the lubrication system is faulty, causing the
motor to start with the increase of load torque, the rotor of automobile starting
motor sweeps the bore, resulting in the increase of self-friction of starting motor.
1. After connection is properly done, go to [BTS] and select [Start System Test].
