krispots Posted May 17, 2010 Report Share Posted May 17, 2010 Hi there! I'm new here :)I'm trying to build a circuit that can charge a deep cycle battery from a 200w DC power source, input voltage is 12VI have read that charging a lead cycle battery requires three stages.the first stage requires a constant current to be applied to the batterythe second stage requires a constant voltage while gradually reducing the currentand lastly, the float charge, where it just keeps the battery from self-dischargingis this entirely accurate for a deep cycle battery?if so, can anyone point me to the right track? i have basic knowledge about op amps, diodes, transistors, transformers, logic gates, full wave rectification etc.etc.thanks!
