Question on battery relocation and water splash

I'm planning on installing the battery flush with the bottom of the frame, under the rear seat foor pan, on one of the rear legs of the central X-member. It will be subjected to indirect water splash from the rear wheels.

Other than possible corrosion, is there anything that can happen? The voltage isn't sufficient to short itself out, even with water on it.

I have no desire to install one of those large plastic battery enclosures for a small group 75 battery.

Food for thought, if it can be exposed to tire water it is exposed to tire stones.

Sounds like trouble, thats why it is protected.

 

You're ok, as long as the top isn't open to the interior. I'm thinking you have sealed it up? If not you'll need drycell type like optima because of the gasses coming inside the interior.
As far as pebbles go, i shot a battery with my trusty 410 long ago expecting some dramatic results...ever been peppered with bird shot bouncing off a battery at close range? Bad move that. Can't say i've ever done it again. They are pretty durable those battery cases.

 

I have my battery located right behind the right front tire, there is a splash shield there, but the top is open, been like that for five years never had any problems.

 

it's fine, a solid mount with a simple splash/stone shield will serve you well.
semi's, box trucks, stake trucks, heave equipment been doing it for decades

 

Here's mine.

No problems with either Optima or regular wet cell.

 

my battery is in the rear of the trunk

 

No problem, Henry did it on the Model A.

 

Chevy did it all through the 30's & 40's and even into the 50's in the trucks, as did a lot of other makes. They had a solid bottom and front to protect from stones. They also used a nice access cover, which was a good thing.

 

And on the Model T's, too.

 

It's on the outside of the car, under the rear seat riser.

Will do the same. Perhaps an access cover also.

Thanks for the input.

 

I always do it that way. Like C-9 I add a sheet metal shield for heat or rock damage.

I've never built a hot rod with a trunk mounted battery. Except for a race car, it always makes me think that there was not enough planning and it got the, "oh shit where do I put this now?", treatment. If it's a gasser then you need the forklift batteries in the trunk. But of course that would be part of the plan.

 

oooo...I like that idea, nice and close to starter and altenator/generator.
Worked out good eh!

 

I modified the original battery tray in my '32 Roadster which is a metal rock shield. I use a Odyssey PC925MJ battery that is encased in a metal box. The Odyssey metal enclosure not only protects the battery from external damage and heat but eliminates the expansion of the battery which increases battery life. I'll never buy another Optima and those issues have been covered in previous posts. The FOGGER
