The ckt which i have shown is for giving battery backup to a system which should work continuosly, system req 5V and i have used 12 v battery , now when the light goes, the battery is connected to ckt via diode and when the battery is near to danger level of discharge it should cuttoff itself from the load.
and when the ac power is regain then the battery should charge but little faster,
100 ohm resistor should be changed to 47ohm
