No need for lids, as they are individually (or in pairs) secured to the boxes and the boxes are secured to the sole (Eng-Genset & Aux boxes) or secured to bulkheads (House Bank boxes)

RANDOLPH ACID PROOF BATTERY BOX BLACK PAINT #345 from Aircraft Spruce

Thanks for this.

I wood like to think that an ordinary paint would surfice on the inside as long as all the joints are sealed with expoxy (even Sulfuric acid would take some time to eat its way through 3/4 marine ply). I've posted the B48 builders inquiring what they use .... everything is done "top of stds" on a B48.

Also keep in mind the batteries are sealed so the probability of acid leaking from AGM/Gels is significantly reduced (unless the casing cracks which is highly unlikely).

That said, acid-proof paint on the adjoining ends of the box and the removal side won't be adequate as I want a "sealing effect" of some sort.
