I was thinking about moving my battery to my trunk just for space reasons under the hood. so I thought, all you audio guys do that all the time.. isnt it bad to do that because of some gas that the battery puts out while its charging? I have the factory hyundai battery...

 

[cusumtib]

umm never heard of that before in my lifetime!

 

[qbytiburon]

they can leak and if u relocate them u need to put them in a special box i believe.

 

[fleishelja]

It puts out hydrogen... I just looked it up. rumor has it that its bad for you... anyone know if thats true?

 

[Diode Dynamics]

I'm 99% sure that's not true at all...

 

[GTea]

hydrogen is also extremely flammable if thats true.. which I don't think it is.

If you have a unvented wet battery in a closed space such as your trunk you run a big risk of explosion. That is why most use a optima dry cell for the trunk.

 

[fleishelja]

all of them say in there that lead-acid batteries produce hydrogen as a by-product of charging. so if the battery is in the car then its going to leak hydrogen gas into your passenger compartment.. I'm not so sure I would want to relocate a battery to my trunk unless its a gel cell anymore

 

[MoogLe]

yep, coincidentally, i asked T.C. about this about a month ago since i've also heard of it and he said that it's true,

he said that the only batteries that dont do it are dry cell batteries like Optima batteries.

but if you dont want to get an optima you can get a sealed box with a hose that will vent the gasses outside the car, dont know how effective they are though

Exactly.. do it properly and get a sealed box for the trunk to hold the battery and run the hoses for proper ventilation.

now that I could see working

juss buy a optimia battery problem solved

 

[Chuckie]

Any battery can be used, but you need to use a sealed box with a vent tube that routes to the exterior of the cabin.

Every nhra-legal relocation kit will come with the proper seals and vent tubing.

 

[fleishelja]

ya unfortunately our stock batteriers dont come with the vent tubing. I sure wish they did though because I would have had my battery in my trunk by now. instead I have to save up for an optima battery

 

[antiquity]

just for the record optima batteries are *gel* cel not dry cel batteries. They still have the possibility of gassing when they charge but because the resistance in thecells is MUCH higher than a wet cel battery it takes pretty extreem heat to make this happen.

I wi be relocating y red top to the trunk in the next couple of weeks for weight distroution purposes.

 

[Chuckie]

The tubing is not integral to the battery. The box has a lid with a rubber seal. The holes for the +/- wires go through grommets and then a vent tube runs from the side and you route it to a hole in the body that will vent the gas to the outside. The vent tube is to keep the fumes from building up in the box and to also protect the driver from constant, though minimal, exposure.

Here, this is my set-up for the probe:

Id play it safe on this one. Doesn't seem like it would be difficult to do.

yea, my bad

c-man, where did you get that box?

 

[Chuckie]

Summit. Its the Moroso box. NHRA-legal. They only come blue, but I painted it.
