    Has anyone added a 2nd battery under the hood that is easy to install. Or is the easiest option just to toss it on a frame rail in a box? I want to do one, but I want to do it quick. I'm running 2005 V10. Thanks, nick.

    Well kinda loaded question. Easy and quick usually don't go together

    I know. I was just hoping. I don't want to relocate anything. Don't mind fabing something up either

    Use the search function above. It's a subject beat to death. Like charging, low power, lights dim and extra battery charging.

    I did the search. Lots of guys asking about it, but only a couple have done it. Seems like there is always a catch for someone who has done it.

    Easy way is to relocate the stuff behind the left head light move it back and down and you be able to squeeze a battery in there.

    I never did it I just put a bigger amp alternator.

    I get in big lots I rather plow with head lights off. I see better and when I work with a other truck, we are not blinding each other with head lights

    I did a post on this. However this site does not display signatures when posting from a droid. It is more involved than people think to make it look factory.

    Big 3 is a much better upgrade than a second battery to me.

    Why do you need a second battery?

    No, its old school. When you leave it on like every other night, your battery doesn't stay good for very long. That is not really why I want to put a second battery in. My fuel economy is around 9-9.5 around town, and I thought another almost 50-60 lbs might get me down to a solid 9 mpg

    I try to always tell people to read up on the charging / power issues addressed here in the past. Grounds and cable connections play a big part in charging too. You can buy after market alternators or have yours upgraded for about a $1.25 an amp.(If you have a good shop in area) An alternator only puts out about 1/3 it's rating at idle. We plow just a bit over idle RPM. Your lights and heat blower pull around 20 amps. About 2/3rd's of a 100 amp alternators out put at idle.Having 2 batteries just delays the low voltage end point. You have other issues like an isolator setup to keep the charging and batteries from battling.
