Battery Charger CIRCUIT

Hello ,
I am trying to build and simulate a whole Wind Energy Project . I am done with the induction generator and everything . Now i am trying to build a Battery Charger , for Acid batteries of 100Ah 12V . Can anyone help me with the circuit and its ratings ( simple description )

Do not just take a web circuit an use it without understanding the chemistry/charging of Lead Acid Batteries. Probably 80% of the circuits out there are either wrong or too simplistic to get good utilization of the expensive batteries. **broken link removed**.

I deem **broken link removed** to be reliable. Stay away from PULSING!

Well , thank you . these links provide a good feedback on the charging and discharging theory . Yet , my problem is basically with power electronics , thats why im asking for a circuit that would solve my problem , i know websites provide faulse circuits , so i thought this forum would provide some usefull help
