The old way of charging battery 
Effective and simple way.
---------------------------
Warning You must be careful when construct this circuit because of direct contact with a killed voltage of 220V
---------------------------
The lamp set to determine a constant limited current through the battery.

            300W
I= ---------------------------  = 1.4 Amps
    (220)-(12+1.4) V
--------------------------
No heat sink
No more Regulators
No more power transistors
Just a waste of power in the lamp and this can be solved by using this lamp for lighting your room ^^
 
Enjoy..

Bridge rectifier must be looked at, flip your bottom diodes upside down

You are right.. thanks

And you have to take a decission were to place ground. Having it twice at different potential is bad and short circuits everything between both grounds.

In reality in my circuit I have two reference voltage one for the nutral of my Ac voltage . And one for the the negative portion of bridge rectifier .. so two grounds(reference) but not the same . And since the program considering it as one you are right i get to remove the nutral one .. i deal with nutral (reference of my AC )to my circuit because i have two phase AC voltage to home inlet

I'm going to try to resurrect this, I don't like that 41.8A inrush current, I got a trick up my sleeve you might like ;)
