I have two leads coming off the battery. Both have a spade fitting to connect to the battery terminals. They end in a female cigarette lighter piece. As I understand it - and you would need to check this - the red terminal (positive?) goes to the centre connection of the cigarette lighter fitting. I have to take the spade fittings off the battery to put the terminals of the charger on. The terminals are marked red and black. So the red lead should go on the red terminal and so on. I was not careful and when I disconnected the charger I put the cigarette lighter part back on with the red to black and vice versa! The next night that I went out - actually to show off how it worked! - nothing happened. A call to Bintel told me the sad truth. You will need to find out more about cross polarising for your scope, possibly from another Celestron user.
As previously mentioned I use two batteries: one for the scope (7ah) and one for the dew heater (18ah) because I have a heater control on the dew heater and when it cuts in and out it causes spikes in the current and this can play up with the tracking a little bit.
Hope that I have not confused or frightened you more! 
Cheers!

Thanks Popeye,
My unit has a built in female cigarette plug, so there is no messing around with wires. You just plug things into it that have the male connector and away you go. So hopefully i wont have your problem.
Cheers
