> What are you going to use it for ?

I have a battery charger that uses that kind of connector.  They
give you a pigtail to wire to the battery.  I bought some extras
at my local hardware and use one wired to a volt meter so I
can read the voltage at the batteries.  The battery pigtails stuff
under the carpet when not being used by the volt meter or the
battery charger.

made--and cheap.  Get them from Digi-Key.  Here's the plug:
