Battery box or tie down.

[gtflash]

I'm looking for recommendations on ways to tie a battery down that have stood the test of time. Preferably with pics. I'm not sure I trust a plastic caravan box. It's a sealed optima so no venting required.

Thanks. Gt

Boxed and Strapped...hundreds of hours all weathers....no problems
I've also wedged (filled gaps)it in with rubber to stop any movement

Same as Maxi [emoji106]

Any pictures or recommendations would be great. I need a battery box / tie down system for my second battery. I have a few "marine" battery boxes but they'll all rather poor quality and the lids are a loose fit - all a bit of a lash up.

I was thinking of something like this, but ideally doesn't battery want to be fully contained.

I've always used something like this:

Battery Box

with closed cell foam padding inside between the battery and the case, and then a strap over the case. Case and strap screwed down to the deck or other anchoring point.

Just one thing to think about, I used to use a battery box and it was a royal PITA, I think the box was installed before the console so it was a real struggle to remove the battery due to the space between the lip of the battery box side and the bottom of the console shelf - so I had to do some thought about what options worked for me and I couldn't find anything off the shelf, so i had something made.

This is what happened to my battery box when I tried to remove the battery's the first time...



I got the batterys out but the box was a total mess, so I had to cut it down, I made a bit of a try with an upright side to support the externally mounted battery switch and ran with this for some time, and it worked well with the batterys strapped inside - meaning I could lift the batterys out the side for charging at home or checking the connections.



I didn't like the idea of the open top, and not having any side protection for the batterys so I drew up some drawings, and had a new larger box made, giving some extra space for cables, and also so I could internally mount the battery switch so this was had better protection as well.

My idea was similar to the old cut down box, with a tray and one upright side left for the battery switch, then a U shaped bit to slide over and then finally a lid to cover the top.





The box is made of marine stainless - I know this sounds like a recipe for potential disaster, but the inside of the box is lined with high density foam, and under that lined with a heavy duty rubber insulation, and each battery is independently strapped down - The batterys have more support now than they did in the old box.

Due to the removable side, removable top and cable entry holes the box is not air tight - so no issues with venting.

I like that. 1mm spare in width is close

So foam on inside is what stops battery banging through the roof? I bought a box a while ago but rubbished it. Maybe I should find some foam or rubber

[SteveHall]

No - Each battery has its own strap, and then some blocks on the base of the box - they stop it moving, the high density foam is in case they somehow work lose, i dont want them shorting on the metal box.

In the picture i posted before you can see the bight orange straps, and then the black blocks bolted onto the base stop the sideways movement.

Like Steve says if there is any room for movement on the inside of the case then the battery (or batteries) need to be strapped. If it's one battery in a snugly fitted and padded case then you can strap the whole lot on the outside of the case.
