battery in trunk

86_302 · 02-03-2008, 05:30 PM

when i mount mine in the back i wondering if i need run a vent for it? i've heard the fumes they put off are pretty bad

donutbandit · 02-03-2008, 05:31 PM

Absolutely. They are explosive. If I was going to do a trunk battery, I'd get a solid gel type.

86_302 · 02-03-2008, 05:39 PM

well i have a red optima which i think they claime to be sealed?
does anybody know of any pictures related to this?

Ltngdrvr · 02-03-2008, 06:15 PM

Optimas are sealed, no outgassing.

Correct me if I'm wrong, but I think that if you go through tech at a NHRA track and the battery has been relocated-the enclosure has to be vented to the outside of the car, and you have to have a working master disconnect switch. Mine is under the hatch with no firewall to the passenger compartment-no vent-and no kill switch.

You are correct. Relocated battery requires a sealed box and master disconnect switch to be NHRA track legal. The sealed batteries are not exempt.

ok i got a buddy says he has and NHRA book and it says that his optima in the trunk doesnt have to be sealed or vented. Can someone disprove this ?

From the NHRA website:

http://www.nhra.com/contacts/tech_faq.html

Quote:

I have a street car that I occasionally run at the strip. I've relocated the battery to the rear. What else do I need?
Any car with a relocated battery must be equipped with a master electrical cutoff, capable of stopping all electrical functions including ignition (must shut the engine off, as well as fuel pumps, etc.). The switch must be located on the rear of the vehicle, with the "off" position clearly marked. If the switch is of a "push / pull" type, then "push" must be the motion that shuts off the switch, and plastic or "keyed" typed switches are prohibited. Also, the battery must be completely sealed from the driver and/or driver compartment. This means a metal bulkhead must separate the trunk from the driver compartment, or the battery must be located in a sealed, metal box constructed of minimum .024 inch steel or .032 inch aluminum, or in an NHRA accepted plastic box. In cars with a conventional trunk, metal can simply be installed behind the rear seat and under the package tray to effectively seal the battery off from the driver. In a hatchback type vehicle the battery box is usually the easiest solution, since the alternative is to fabricate a bulkhead which seals to the hatch when closed. At present, Moroso is the only company which offers an NHRA accepted plastic battery box, part number 74050.

Notice there is no exception regarding the Optima battery.

how about at an IHRA track? same rules?

Jax Rhapsody · 02-10-2008, 06:22 AM

Ha!!! I just thought of something put the battery where the spare tire would be.

All batteries in the back of a hatch must be in a sealed vented box regardless even if it has dry cell technolgy or not.......
