Emergency truck died

[epowers777]

Ok my battery light started blinking. thought it was my belt slipping. tonight my electrical started going out, first the radio then stuff on the dash went weired. i shut the truck off and it won start up again. The batterys are reading both 11.4 Its raining so i couldnt unhook and test the battery's individually. So is it my Alternator or battery?

I have no cars i wrecked my honda please help.
