Proper way to store a 2nd battery inside the trunk of a car?


Recommended Posts

Since everyone will be buying a trunk battery soon, I figured it would be useful to have a topic on how to properly install a 2nd battery. I've read on google that having a battery in the trunk not properly secured is dangerous when you get into an addident. They say that it's possible for the battery to break through the back seat upon a collision.

Also do I have to worry about ventilation for the battery? XP3000 to be specific.

Post your suggestions please.

If it's a lead-acid type battery, you need to put it in a sealed box, secure it, then vent it outside of the vehicle.

If it's a gel-cell type battery, all you need to do is make sure it's secured, and protect the terminals from accidental shortage. The battery you mentioned is a gel-cell type.

The battery he mentioned is a sealed AGM battery. You only need to worry about venting with a traditional flooded battery.

With an AGM or gel cell battery - just bolt it down and you are good.

^^^ This ... just secure it and you will be good to go

Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born.

My penis is bigger than your penis

I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle.

Well I'm looking at the picture on http://www.audiosavings.com/products/Car-Battery-and-Power-Cells/XS-Power-XP3000-3000-Watt-Power-Cell-Car-Audio-Battery-Power-Stereo-System/XP3000.aspx

and it doesn't look like it comes with any brackets for me to bolt down. Would I need to go to home depot and buy them?

Direct me in the correct material needed for securing this battery in the trunk please :)

I'd build a small wooden box to fit around the battery, bolt that down then use some threaded rod into the wood, either a piece of wood or scrap metal across the top, then some bolts on the threaded rod to hold it down :good:

i pulled out my dick in class many of times and had it shown. get over it bitch...stupid open legged hairy beavered bitch...

going over rms = smaller box, under rms = bigger box...

Low voltage doesn't blow amps. That's a myth.

A router that does the sub holes makes rounded edges also?
