How to properly secure your battery in your E30 |

Here's a little writeup I just did. I figured I'd post it here as well.
I'm Auto-xing tommorow all the way down in SA so to not waste my time I figured I'd better make sure I pass tech and make sure my battery does not move. The "universal" battery tie-down autozone sells is not as universal as the name suggests. Eventually I'll move the battery to the trunk, but this works for now. |
|
Home Depot tie-down:
I used:
2x - 8"+ x 1/4" thread
1x - 12"+ x 1" x 1/8" plain flat metal strip
6x - 1/4" nut
3x - 1/4" washer
2x - 1/4" lock-washer |
| |
Here is a picture of the battery and how it sits in stock form. It's going to go across longways across the battery to hold it down. |
|
|
Take out the battery. You can use those two holes already in the battery tray. I had to drill the inner hole out a very little bit to fit my bolt through. |
|
|
Cut the thread 8" long, and put a nut at the end you cut. Then melt/mash/weld/whatever the nut to the end so it doesn't move and you make a bolt. Repeat on the other end. If you can find 8" 11mm bolts somewhere you don't need to worry about this. |
|
|
Cut the metal stip 12", put the battery in and mark it where the bolts will go through. Then drill it. |
|
|
This is what the setup looks like not in the car. |
|
|
Thead the bolt through the hole, then put the washer, lockwasher, and bolt down, then tighten it up. Repeat on the other side. |
|
|
Put the batter back into position. |
|
|
Slip on the metal strip, tighten it on. Tighten one end until it is almost snug then tighten the other one till it is almost snug. Then you can tighten them all the way after that. Otherwise one side will be tigheter than the other and the metal strip will bend and look awkward. |

Viola! That baby isn't going anywhere. |
