Re: (ET) Battery box corrosion
After much reading about and discussing this problem I have concluded that
I do not have time now to replace even one of the two battery boxes. So
until that future time, I have scraped away as much corrosion as I can.
Now I need to put another set of flooded batteries in the tractor and get
back to mowing. My concern is to minimize further corrosion, especially
on the frame, but on a student budget. So I have a couple ideas that the
rest of you might want to sanity check for me.
The old battery tray is shot and does not appear to be a durable design.
I bought battery bags but the perforated/corroded metal is a bit jagged so
a protective intermediate layer appears to be needed. It seems I could
fashion some ABS plastic into a shield by cutting it into a plus shape and
bending the sides up. Putting the bags in next and then the batteries
seems reasonable. Using wooden shims on the outside of the battery bags
ought to work well enough to hold the bags up, keep the batteries from
sliding around, and prevent the wood from being soaked in acid (which
seemed to contribute to the corrosion in the past).
But the drain port is still bugging me. I am debating leaving the bags
without drains. The main reasons in favor of that are:
1) the front drain port has been leaking acid onto the steering gear and
corroding it.
2) the ABS plastic sheet with merely a hole in it would not keep all the
acid off the frame either (during runs up and down hills)
3) I have not been able to think of a simple way to attach a hose to a
hole in the ABS plastic (or the battery bag). I do have some of the two
part PVC solvent cement...
Feedback?
