Loss of power

[teamswitch1]

For some reason my truck keeps draining my batteries overnight. I jumped truck a couple times and alternator is fine putting out power. Any reason the truck would rain batteries other than headlights/done lights left on? I can't think of anything. I have an 02 F350 btw

Go have them tested. They may just be bad.

It would be a good idea to have the alt tested as well. Just because it is putting out voltage does not mean it's good. There could be an issue with the voltage regulator or diode.

Got it thanks, turns out both batteries went bad. One had a bad cell and he other was steaming and smoking smelling like H2S all problems cleared up
