This is a basic electronic project on how to make a Lead Acid Battery Charger. The circuit can be seen below:
Thic circuit furnishes an initial voltage of 2.5 Volts per cell at 25 degrees celcius to rapidly charge a battery. The LM301A compares the voltage drop across R1 with an mV referenced set by R2.
The LM 334 temperature sensor should be placed by near or on the battery to decrease the charging voltage by 4 mV/ deg cel for each cell.
