Jeff,
I'd offer to order replacement cells for the customer, for as many
of the 16 as the customer wishes to replace - let them decide. As
you have already made your margin on the sale, you could offer the
replacements at a substantial discount just to cover your time and
expenses. I'd decline offering "repairs" or even more than cursory
advice that might come back to bite you years from now when one or
more cells fail prematurely.
Re loss of acid: of course the voltage is holding fine - the
amount of electrolyte in the cell doesn't affect voltage. But you
are guessing at the amount of H2SO4 to add. A bad estimate could
also come back to haunt you down the road.

Esteemed
Wrenches,
I need your advice on this most unfortunate situation.
I arranged a purchase of 16 Trojan L16 RE-Bs for a
client and they went to pick them up. They didn't
secure them well on their flatbed tralier and as they
climbed their windy mountain driveway they lost 4 of the
batteries over the side of the road and several more
fell on their side on the trailer.
The damage falls in 3 categories:
1) Broken or cracked posts, caps and handles,
2) Loss of Acid
3) Unknown damage due to shock of falling . . .
It's the last category that concerns me - I'm
recommending they replace the ones that took a tumble
enough to break posts. (although experience with fixing
posts would be welcomed)
And the loss of acid doesn't seem extensive - the
voltage is holding fine - perhaps we'll just add water
or perhaps acid and water - we'll work that one.
(though any input on amount of acid lost before needing
to add acid would be welcomed input) (all but one seem
to be above the plates still).
But I'm seeking advice on whether you can trust an L16
that has violently fallen on its side. Can the force of
a fall like that loosen or crack plates and cause
problems that show up later?
Here's the summary of damage:

Thanks!
