This simple nicad battery charger uses a current regulator with the LM350. This integrated circuit must be mounted on a heat sink. The resistors determine the charging current and 7.5 V transformers can also be used.
An inproved version of the circuit CIR129E is shown here. The resistorR1 must be at least 5 times...
