Remark: Refer to ripple and noise 

1. Measurements shall be made with an oscilloscope with 20MHz bandwidth.
2. Outputs shall be bypassed at the connector with a 0.1 uF ceramic disk capacitor and  
a 10uF electrolytic capacitor to simulate system loading.

Charging Characteristics

 
1 .A state diagram for sealed-acid 
battery  harger is shown in the left This charger,called a dual level 
float charger,  has three status,
a high current bulk charge state,
an over-charge state,and float charge state.
  


2.In the first state,the charger  acts like a current source providing a  constant  charge rate at Imax, the charger  monitor the  battery  voltage and as it reaches  transiton  threshold,Va,the charger begins its second state.  

3.In the second state,the charger  regulates  the battery at an elevated  voltage,  Vb,until the charger rate  drops to a specified transition current, Imin,, When the  current  tapers 
to Imin,the capacity of  the cell should be at nearly 100%.
 
4.In the third state,the charger  maintains a  precision voltage across the battery  
to optimize stand-by life.
