I have seen a few cars with a 16v AGM style battery in the back with no box around them and no rear firewall.. Is this ok??

I want to make sure before I redo a car.

Thanks,Mark

NHRA Online:

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.

I swore I remember seeing something that said a gel battery didnt need a box. Maybe it was amended from a few years ago.

I though so too, but it does not appear on their online FAQ. However, in the rule guide, it actually shows the calculations for the bolt sizes for the battery hold downs, where as online you get the 3/8" statement. So maybe the AGM is mentioned in the full rules.
My opnion though, keeping a battery covered while close to a fuel cell, might eliminate a dropped wrench turning into a fire ball.
