A Guide to Building Battery Chargers - Circuit Basics
May 19, 2020 · This charger can charge both NiCd and NiMH batteries: The circuit is designed to charge a 12V battery at 50mA. The LM317 forces a 1.25V reference voltage between Vadj and Vout. To calculate the value of R3 to give a particular charging current, use this formula: R = V / I. So with V at 1.25 volts and I at 50mA, R = 1.25V / 50mA.
