Being a RR fan (records and railroads), I have a few of these bottles.
I understand they actually contained battery acid to replenish wet cells
that used to power railroad signals. I believe they actually inscribed
"battery oil" but if you pour oil in a battery you ruin the electrolytic
process.
I have a couple of other bottles that have the same shape, but are not
"Edison". I'll have to dig them out to see who took over.
Some interesting items relating to this:

While Edison may have invented different cell types, the nickel-iron cell
was his widely used battery. It is a cousin to the nickel-cadmium
battery. Interestingly, a European company (now part of Saft, I think)
was called NIFE batteries and made mostly nickel-cadmium batteries. But
look at it NiFe - nickel-iron - Edison's cell. And now, in the third
link, some people are reviving it.
I think the use of "primary" battery at the Edison site is a misnomer
unless there is a non-rechargeable battery they are referring to --
or I'm confused.
