Place a low value resistance and a fully discharged capacitor in series with each other to the battery. The capacitor will charge rapidly. Repeat this procedure again. The lowest time charging time will indicate that the battery is fully charged.

Answer / gbs
when the battery is in charging condition it draws power from the charger and when its gets charge completely its may take 0 or nearly 0 amp of current. So if u have installed ct then u can know from current.

Answer / tarequl islam mukul
While most chargers have a light that turns from red to green when the battery is charged, some very inexpensive ones don't. The light simply comes on when a battery is in the charger telling you that the battery has connection. These are slow chargers that take about 12 hours to fully charge a drained battery but the charge is slow enough that the battery can be left in the charger indefinitely without harm. If you have the charger instruction sheet it should tell you.

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
