Only because you can't get up that high to see!!! roflmfao!!

I climbed onto the bar work and had a look, I just can't find them.

Lucky you didn't fall in little fella ... or else we'd be looking for you in there also!! LOL

OK, Deerings should certainly know what they are doing which only makes it more confusing. Exide should be a reliable battery especially 4 different ones... so something is really odd.

This is a very perplexing problem you have brought to the all knowing Forum... you should be very proud

If the top is "very very wet" every day then the battery must be gassing like a bitch. That is usually only from...
a shorted cell, can't be that on 3 different batteries, or
too high a charge voltage but 13.2 to 13.5 is fine as the Battery shouldn't gas until 14.5, and
that pretty much only leaves internal temperature getting too high.

Have you checked the Charging voltage with the engine at about 2200 to 2500 RPM?

You shouldn't need a heat shield unless the Battery is in a very unusual spot but maybe a Shield will cure your problem. You will know if you cure it because the wet top issue will disappear

I go with evil twin on this, especially the highlighted, have you tested yet?
You could take it back to Deerings and get them to check the whole system, as they did the work.

I know others with similar problems. When you say your batteries have CCA and are deep cycle then they must be, what they call dual purpose, and this IMHO is the problem (or part of).
We know we need CCA for a starting battery, and most folk have an auxiliary battery tray for auxiliaries, so a purpose built for each designation is the go, and a wet cell handles heat better under the bonnet.

The other problem that is servicing is sealed batteries, if they have a high heat or high charge situation they can't be maintained. Just another casualty in the 'lazy, throw away world' that it has become.

Other things to check over is the changes we make to our 4bys from OE. In this case the engine bay cooling. So a lift, spotlights, winch and other add-ons can effect this. Make sure the skirts from the inner guard to the chassis are in place and in good order. The heat is supposed to be carried away, tunnel like, under the fire-wall.

Good luck.
