guyz i need to charge a 100Ah lead acetate battery and want to design an intelligent charger for it using an avr can any 1 provide me the schematic for it plz
Lead acid is the least critical type of battery to charge. use a 13 or 14V output from your mains 220V, and limit the current via a power resistor of 10 ohm or so.
if you want it to be "intelligent" you can build a small micro controller circuit that will cut off the charging when battery voltage reaches 13V for example..
