    Hi again,

    Thank you for important informations about SLA charging rules. My SLA is 12V-7.5Ah.
    -Yes I will use Constant Voltage.
    -As many professional charging device producer say that PWM is the best way to charge SLA batteries. (I don't why it is). So I will do PWM charging system.

    I have just uploaded an image. Which is better or any comment will be very very important for me.
