I need to modify the output voltage of an Astec AA23260 server power supply from 12V to 13,5V to be used as a car battery charger, can someone help me?

It is a simple resistor change;
but it is imperative that you have the schematic to determine which one.
 

Hi,

A power supply is no battery charger.
To build a charger you should have a current control also.
Read how a charger should operate.

Without series resistor you may overload the power supply. With series resistor you may increase charging time and power dissipation.
