Have the "NOS" batteries ever been activated? (had acid put in them?) If not , then they may still be usable.
As a acft mechanic in the 60's/ 70's Thats all we saw was "rebats" and some were white on the sides, black on top. Those may have been the smaller R-25's. Also some (the later ones?) had black caps.
The S/C's and comp cars had the batteries (2) end to end behind the pass seat. Must have been the R-25's due to the smaller size.
