Replacing battery compartments?

[TheThing]

I have just received a Meade ETX-80AT (thanks Lee!)

As standard it comes with a battery compartment that takes 6x AA batteries (9v in total).

I can't see AAs lasting very long at all, so want to power the scope from my power tank. Thanks to Peter, I have purchased a convertor from Maplins which will take the 12v power tank down to 9v.

The next question is how to connect it. I don't want to cut wires etc, as it would be useful to put batteries in for w/ends away when the power tank is too much to take as well.

Is there some sort of connecter I can purchase instead? The battery compartment clips in with the sort of connector that you normally use with the rectangular 9v batteries (PP3)

PP3 connectors will snap into each other - you just have to reverse the polarity in one of them! Maybe you could make a connector from the power supply with a PP3 snap connector that would do the job?

Ah, genius!

If I take one of these and 'wire' it up the wrong way round to one of these I can then just connect it using the 12v/9v convertor that I already have.

Have I got that right?

Make it so!!
