When i start the car its at 14.3-14.5. then when i take off and turn up my head unit it goes down to about 13.2-13.5 and stays around there. i dunno if this is normal or not. After about 10 minutes of driving my "Battery Saver Active" light comes on. When i read the voltage up front its right at 14v but on the stinger gauge in my car it says mid to low 13s. Any suggestions?</p></blockquote><p></p>
