May I assume that the threads on the Prototypes are more robust than "the competition's" design, since the amount of force on the cell by the two spring/contact battery plate assemblies is greater?
Threads on the Prototypes are 15/16- 24tpi which is a "*******" thread, meaning that it is a non-standard thread. Slightly coarser than the 15/16-32 UN thread that is on the Novatacs and old HDS EDC series.
