Comments/Questions: Bob,
I have an RV-8A with two batteries (Odyssey PC560, I think). They are
mounted on the side, under the floor panels. I am in the process of a
condition inspection and was surprised to find that a liquid (now dry) in
the region of the battery had removed the wash primer used by Van for the
quickbuild kits. I removed one of the batteries where the liquid had
pooled, as it appeared that this could have been battery acid, however,
the battery looks perfect and I see no evidence of leaking (I assume that
this is not possible anyway.
It is possible that was I am seeing is a result of the plane being cleaned
with an alkaline-based cleaner that ran down the interior of the
fuselage? Any other ideas?
Thanks much for your time.

I think it unlikely. RG batteries contain so little
liquid that you would have to squeeze the plate/
separator array with a great deal of pressure in
order that you recover any liquid.
I think it more likely that you're seeing the
results of a pooling of condensation. The interior
surfaces of every airplane gets wet when descending
from cold flight environments into warmer and
moister airport environments.
The 'hell hole' behind the rear pressure bulkhead
of a biz-jet literally rains inside as the airplane
descends. We had to build rain "gutters and downspouts"
into certain areas of the cabin, under the upholstery
to prevent water dripping on the passengers during
descent.
In any case, where ever the liquid came from
it wasn't from the battery.
