I got this new battery for my cobra, and I will fit it into the cobalt as well. According to my scale, it is only 13.5 lbs. The stock battery is around 35-38 lbs, so it should save me somewhere around 20-25 lbs. Combine that with my spare tire delete, and I've lost around 55-60 lbs.

I'm going to run it full time in the cobra, and on track days for the cobalt. I know people who run this battery full time, and have no issues starting the car. I think as long as you don't run many accessories with the car turned off you should be just fine. I might have to fab up something to hold the battery in place because it is quite small, but I'm not worried. I also might have to do something with the terminals if they don't hook right up as well. The battery also does not need to be vented like the stock battery as it is a sealed acid battery, and does not emit gasses.

This is where I got the battery from: http://www.batterymart.com/battery.mv?p=ODY-PC680

 

sweet
that thing is tiny

I'll back that up . I ran one in my Trans Am . It was called a Dynabat though , case looks exactly the same though . A friend also run one in his 96 Z28 . Its life is short when the car is turned off and u have something running like the radio . Very nice little weight reduaction though

 

yep, the dynabat is the same battery, just a different label. exact same internals.

 

you need to put that thing in a case venting outside if you're going to run it in the cobalt.... you don't want the battery venting into the cabin. it would work fine under the hood...

 

except for the part where he said it doesn't need venting

 

Looks like a nice weight shaver, semi LOL

It's sealed...

 

Whoa, that's a great amount of weight savings, can it be mounted in the stock location? (dimensionally speaking)

 

i just didn't know what to believe because the website lies about its advertising:

being a tanker for 6 year in the army, i can tell you these have no similarities to tank batteries. they're lightweight: tank batteries weigh almost 60 pounds each, they're drycell: tank batteries are not, they're high output for short periods of time: the 6 tank batteries put out about 2000cca each for a good 4-5 minutes

 

yeah, I'm going to try and mount it in the stock location. You can see by the picture that the battery is small, so it might take some work to mount it securely. I will try to use the stock battery strap, and fill in the extra space around the battery with maybe some blocks of wood.

I also bought one of these battery tie downs for the cobra, which I might be able to use in the cobalt.

on my old s10 i ran something similar to one of these batteries. the way i mounted it in the normal location cost like $5 for materials and it never moved... even when i was launching so hard i twisted the frame

anyways this is the stuff you need:

cardboard, duct tape and some of this stuff: foam stuff

take normal battery out and lay the cardboard on top of it and cut it out the same size as all the sides. basically what you are going to do make a cardboard box (minus the top) the same size as the normal battery. go ahead and tape the inside and outside of the box edges so it holds together and spray a couple of inches of the foam stuff in the bottom of the box you just created.

now you need to let it set some, probably 5 minutes or so, just so it gets a little hard, but you want to make sure it's still wet so the battery will stick to it a little. make sure the top of the battery is a little higher than the sides of the box, so when you strap it down, there will be some pressure on it.

then spray the foam stuff around all the sides of the battery and let it set.... viola you have created a battery holder that weighs about a pound and lets you securely mount it without jerry rigging up some craziness
