<p>William,</p>
<p> Our typical battery support : Start with concrete
slab which should be the foundation for the shed the power system
is in, next pressure treated wood of various dimensions depending
on battery height, next 3/4" plywood, next 40 mil PVC shower pan
liner on bottom and runs up sides ~4-5" which acts as an acid
tray. Add batteries. The center to centers of the pressure treat
depends on batteries (T-105s or Rolls CS-21P or??). We've never
discovered any rot, not sure how conduction would happen with the
40 mil PVC liner there.</p>
<p> A wooden support enclosure leaves much more room for
installation flexibility, onsite mods. Many times after a battery
replacement in 15+ years there is the need for new
support/enclosure due to power changes. $.02 from Taylorsville<br>

style="font-size:12.0pt;font-family:"Verdana","sans-serif"">For
years we have been supporting large form-factor flooded
battery trays by setting them on pressure treat 4X4s. We
have developed a cradle we bolt onto a special-order, narrow
pallet jack and roll them over the wood supports. It is not
a seismic solution, but it works.</span></p>

<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Verdana","sans-serif"">Just
today I have learned that at least one large battery
manufacturer is recommending against using any form of wood,
apparently due to the potential for rot and/or conductive
paths. I am told that the solution is steel racking with
plastic covers over the steel. </span></p>
