Single battery

[powerstroke 825]

Can somebody point me in a direction of a thread for this or tell me the pros and cons and what we be wrong with running it on a street truck.

I've run a lot with one battery.. In fact, I only have one battery in my duramax right now.. Only thing I notice is the starter does not turn as fast while cranking. But I live in Florida so my glow plugs don't really have to sit there and warm up.

No problems in the winter here with 1 battery

If you do go with one battery make sure you get the highest CCA battery you can that will fit in the tray.

this might sound like a dumb question, but would it matter which battery you remove? I know the driver side tray is part of the degas bottle and you'd need to get a custom bottle of some sort... but could you remove that side if you so choose without any ill effects?

 

[White_monster]

Shouldn't matter.

 

[powerstroke 825]

So what all exactly needs to be done to make this happen? I would more than likely leave the driver side in due to the degas bottle.

take out the battery that's step 1

step 2 is make damn sure the positive cable won't find ground so deal with that in a temporary or permanent fashion

I wouldn't do it myself I don't think the factory really wanted to install extra batteries and trays if they weren't a benefit IMHO

i know I can hear mine slow down cranking speed even with two 850 CCA batteries
i would really worry about the tax on the system with 1 batt

To me I don't really see how it's worth it. If I were to the point of needing to shave weight that badly id start elsewhere first.

I went the other way I have three AGM batteries with around 850 CCA's each

Is the 3rd on the frame?

It's not as much to save weight as it is to free up space!

Gotcha.... I haven't been that far into building a truck and won't for awhile so that point didn't go through my head... lol

Just move both. Done deal.

Ive ran with 1 battery for about 3 years now and its fine, the battery needs to be pretty solid in the cold but i have started my race truck with a 4 year old optima @ 0 degrees not plugged in, it didnt turn over super fast but it did fine. much colder and im sure plugging it in would be required.

The passenger side battery is the one that is most common to remove for turbo reasons but in fact the drivers side battery would be better. The starter cable is off the passenger side and is heavier gauge than the cable that crosses over from one side to the other. Plus the shorter the cable the better.

You are right about the battery try/degas bottle tho

Would it be a good idea to run a big gauge wire straight from the driver side battery. Or would it make any difference

it's in a battery box in my weather guard tool chest it connects automatically when I key on
so it helps start and gets a charge while driving but doesn't equalize when not running with the 2 truck batteries

it basically preforms as a start boost and then it powers a converter for tools in the bed

I have seen the frame rail setup i like that also but this was easy and tamper proof

I have a 6.0 dumping a battery really isn't an option for Mine with the FICM issues low voltage can create

I havent tried it to see if cranking speed increases any but im betting it would, i think the cross over cable is 4 gauge and the battery cable is 2 gauge, i could be wrong on that tho.

Ok I'll probably do that when I ditch my battery. On the cross over cable is there anything else that is connected to that? Can you just do away with it? Don't want that live end sitting over there

I believe the starter cable is 3/0 battery cable. It's thick. Might be 4/0. I remember it fighting me when I did my relo.
