Battery Box

Rule 3.G.2: ...Batteries located in, or visible from, the passenger compartment must be sealed-type or contained in a sealed battery box.
My suggestion is use an AGM or other sealed battery and forget the box. A box is a PITA if you need to access the battery during the race. Also, even in a box,  the battery still has to be mounted securely. Wallymars-type boxes aren't sealed.

We just have a basic plastic battery box mounted in the trunk. Never had a problem getting through tech with it.

Yes, I remember this came up and this was the brought up before.
Ours is the Walmart battery box.
- The box is bolted to the floor of the vehicle.
- We fabricated metal brackets that clamped the battery through the box to the floor of the vehicle.
- Any excess room in the box was taken up with wooden blocks (it's solid).
- We do have a nylon strap but that is merely to hold the plastic lid on top.

I found that it also helped to fabricate more than one ground cable for the battery (one clamp but leads to multiple different spots on the body) to insure a quality ground.

bumping this for clarification.

my battery is mounted in the trunk of our Sentra as seen here.

my plan is to make a bulkhead to close off the trunk area from the passenger compartment. I assume this satisfies the rule since it is no longer visible? Do I have to make a bulkhead for the shelf where the speaker were mounted and cover those holes?

Thanks!

No cell, so we're good here. My thought is....

Rule 3.G.2: ...Batteries located in, or visible from, the passenger compartment must be sealed-type or contained in a sealed battery box.

the bulkhead now means the battery isn't located in the passenger compartment....the reason to avoid a battery box is that my mount is fairly tight around the battery and I like how strongly it is mounted, I would rather not redo it.

I run a lead acid battery in the passenger compartment. It’s enclosed in an old plastic tool box. If you really like your mount, just find some kind of box big enough for it. Toolbox, an old microwave oven, a mop bucket with a lid...

What someone says they get away with and what the rules state are two different things. 

The minimum is 15 pieces of flair, and if you have 15 that's fine, if you just want to do the minimum.....

Not choosing sides here, just sharing my experience.

I wanted to use the STOCK battery mounting, which was a SINGLE metal base clamp and a SINGLE bolt and the other side of the battery slid under a metal lip which substitutes for the second clamp in the aftermarket mount pictured.

I was told by Pagel in person while I was in tech, "I need to see a metal strap over that battery."

Me: "It's the factory mount, it's a metal wedge"

"i don't care that it's a metal mount. The battery is plastic. That's a 40lb battery full of acid. I don't want a 40'lb projectile flying around on my track when you get hit and the plastic battery case breaks or flying around under your hood arcing out and causing a fire. I want a metal strap over that battery. Now get out of my face."

YMMV
