Battery Charging Problem

[speedEC]

Hello all,

I have finally completed my device designing with help of you all. Now, I have encountered a problem. I have used LM358 IC for monitoring Battery Voltage. Also, I have used L200 IC for Charging my 6v lead acid Battery. I have to feed current to my device and 5v Relay also. Now, I have connected everything to Battery. Everything works fine until I connect the charger to the device. That is, If I connect the charger to the device, the device is powered up automatically. Because, the power comes from the AC/DC Adopter directly go to the device even though the device is connected to battery Thro' Switch. How can I eliminate this problem? Any Help pl?

thanks

I think you may need a relay to isolate them so that it only complete the circute when the relay energised.
