Hi,
You didnt say what you were going to use this for. So I dont think
youll get a great answer. However, if were talking about an
invention of some sort perhaps it is/was best you not/didn't reveal
your intentions. Aside from that, you might look into digital
sprinkler controllers that hook up to a garden hose bib and are
battery powered. They have a solenoid that opens and closes a valve
that you can rig to work for your application. A solenoid is a linear
actuator that operates via an electromagnet coil of wire that has a
plunger that pushes out or pulls in via magnetic attraction. There
are also industrial devices that are specifically designed to do what
you are talking about. Try searching Google. Hear is a search I did:
Go to advanced search:

In the top box type: digital timer relay solenoid batteries
In the domain box type: com
You will then need to look at each one and see who deals
internationally. Take this hit for example from Deep Sea Electronics.
http://www.deepseaplc.com
Which is:

They have distributors all over the world.
With 349 hits, Im sure you will find something in those search
results.
One thing I always do when Im going to build something is look at
what the surplus vendors have available. Gadgets from surplus venders
are great for experimenting around and developing your ideas. Find
the Small Digital Clock And Timer Relay on this page:

From The Electronics Goldmine which ships internationally.

You should be able to disconnect the AC ( Alternating Current ) part
of this and apply battery power. This is because most electronic
devices that run on AC, convert to DC ( Direct Current ) DC is also
what you get from a battery. But before you try this, and since your
venturing into electronics, I would recommend finding a copy of
Getting Started in Electronics by Forrest M. Mims III. It is the
worlds best electronics book for beginners. I first learned using
this book twenty or so years ago. Its out of print, but its so
popular that you should be able to find a copy if you look around.
Good luck with your idea!
All the best,
