Gates was a major provider of the single 2V cell in the "D" size with tabs 
on one end.

NLS used three of them but a 6V monolythic battery with the same outer 
dimensions will also work fine as the tabs soldered to the rear board for 
mounting and to create a series connection.


The only reason batteries are needed to run the NLS is the charger is way
too small run run it directly.
