analysis  evidence  for  the  test  and  maintenance  of  the  battery.  It  notifies  the  user  to 
replace battery in advance when the battery getting aged. 
Cranking  test is mainly  to test and analyze the starting motor. Through testing the 
actual required cranking current and cranking voltage of the starting motor, it can find out 
whether the starting motor works fine.There are several reasons why the starting motor is 
abnormal: lubricating system fault causing the starting loaded torque increasing or rotor 
friction of the starting motor causing the increasing friction of the starting motor itself.   
Charging  test  is  to  check  and  analyze  the  charging  system,  including  generator, 
rectifier, rectifier diode, etc., thus to find out whether the output voltage of the generator is 
normal, the rectifier diode works fine and the charging current is normal. Suppose one of 
the  above  mentioned  parts  is  not  in  normal  situation,  it  will  lead  to  over  charge  or 
incomplete charge of the battery, thus the battery will be quickly damaged and also greatly 
shorten the using life of other loaded electrical appliance.
