So now my question is how come when I turn the truck on the second battery starts to bubble out acid. I have tried 2 other batteries. If I take the second battery and put it on the ground and then hook up jumper cables from one battery to the other it will do the same thing. both batteries are cool to the touch and all of the cables are cool. Im puzzled. I have done this to many other trucks will good results.
Both batteries are brand new and the same kind. 850cca 1000cc. Made on the same day.
Truck specs... 2007 silverado 1500 classic. z71. 5.3l 100% stock. 145amp alternator
I didnt not want to use a battery isolator but unless I can get this to work I guess Ill have to.
