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.
