12 Volt Battery Eliminator Circuit Diagram. When using lead acid batteries it s best to use one series string of batteries to get the desired voltage and capacity. The transformer t1 steps down the mains voltage and bridge d1 performs the job of rectification.
The circuit is nothing but a 12v dc power supply with an ammeter for monitoring the charging current. Here is the circuit diagram of a battery eliminator circuit that can be used as a replacement for 9v pp3 batteries. Before the use of this circuit you need to adjust the cut off voltage range for the auto cut.
Capacitor c1 is a filter.
