Hi,
I have a INVACARE 24 Volt Battery Charger, that used a PIC16F72 Micro controller for a smart charging.
I'll post the pictures later and see if luckily some one met this before.
Thanks.

Not sure what you're asking. A smart charger will adjust voltage and current to give a correct charging profile for a particular battery chemistry.

I may shouldn't use the word 'smart', it is a charger, my question is if it is to modify it's voltage variable which is fixed now.

 

Are you wanting to use it as a separate PSU for something else , ?

The usual way to alter the voltage is to change the feedback resistance to the optocoupler, but as yours is controlled by a Pic, it might be difficult.

You are right, I saw some one convert a laptop power supply into a variable voltage source, I think the Pic may take a feedback from the battery be charged, but there are only two wires.
