Re J.B.146.
hour battery is estimated to be 77 lbs dry & with acid would be in the also above neighbourhood of 90 lbs this is within our limit, but again the dimensions would be wrong being 17" long 9" wide & 7 1/2" high.
The only outstanding feature of this cell is that no separators are fitted, which would give it a low internal resistance.
