Battery hold down in galley?

Postby shoeman » Fri Aug 01, 2008 11:17 am

Anybody here put the battery in their galley? I am, but I'm scratching my head on what to do for a hold down method. There's always the cheapo usual two j-hooks to a cross strap of some sort, but that will require drilling through the floor for the j-hooks. If I did this I'd think I should place some reinforcing blocks for the hooks to go through as the floor is .5" plywood.
Anybody have a more elegant solution?

...try this from Bass Pro http://www.basspro.com/webapp/wcs/store ... rchResults I am sure something similar is available from many sporting good houses....

I am almost to the battery part of my build. I am putting the battery in the galley in the back of a cabinet. (floor level in a battery box).

Have you thought about wide velcro. I have used the 3"x12" stuff and onced it is stuck together, it is the devil to get apart.

Just a thought.

A battery gives off explosive gasses while charging, so if you are mounting it where it could be exposed to an open flame (ie: stove in the galley) I would plan to use a sealed and vented box such as this one.

I think there are a lot of ways to do this, but I would look for the required functions:
    - secure the battery (I wouldn't trust Velcro, but then as a car guy I'm amazed at the lousy job usually done in RVs of all types of securing batteries)
    - protect the floor from battery acid (so a tray, or box, or compartment lining of some sort)
    - enclose the battery area (prevent fuel fumes and sparks from entering, or objects from coming in contact with the terminals)
    - vent the compartment to the outside


Whatever meets those is fine, so I think it makes sense to just pick the cheapest, or most available, or the system you like to work with, as long as it meets those requirements.

If the battery has its own compartment, I don't see the need for a box, unless that's the easiest way to meet the floor protection requirement. For instance, madjacks tray/hold-down in a compartment with a vent would be nice.

If it is sharing with other stuff, then a vented box is probably easiest... just my guess. If the comparment does not have top access, a box might be awkward for installation and removal. The vented box shown would work in a shared compartment, and the since the bottom half is not much more than half the battery depth it might work okay - but a hold-down bracket is still needed inside that (and presumably bolted right through the bottom of the box and the compartment floor).

When I installed a battery in the trunk of a car, I addressed the floor stength issue (the risk of pulling the hold-down bolts through) with a steel strap below the floor, like a huge washer. A bit of thicker plywood could serve the same purpose in the trailer.

Thanks for the input. This battery will be in it's own compartment, and will only be charged at home between trips unless I get a solar trickle panel for long trips. I'd open the battery compartment when that is happening to negate the explosive gas problem. I'm most concerned with keep in it in place on bumps. I'll poke around the local trailer/rv places and see what I can see!

This was my way

My batteries are in the galley, too. They are sealed gel type...
I mounted a base to the deck, then mounted cases to the base. Batteries go in the case. All secure and tidy with easy access for monitored charging.

Which sealed gel are you using? The optima?

I used this for my Optima, kind of the fancier version of the one MJ posted but does the same job.

Optimas a great batteries. But I am using two batteries that were givento me. They are not optimas. Instead they are from an electric kids scooter that was being thrown away...

While both gel cells and AGM batteries are sealed - actually, they still have safety vents - they're not the same thing. The Optima is an AGM design, not gel.

Speaking of being not-quite-sealed, both gel and AGM batteries should have some venting for the compartment when in use, either charging or discharging.
