Ok, I can help you out with this: For basic charging, do as follows:

You should have a screen that has battery type, number of cells and amp rating. Press 'Setup', and Battery type should start flashing. Press up and down to select battery chemistry, and press setup again to move to the next one and change that to suit.

Press down, and you should have a screen marked charge mode. The details you put in before should be there. Press setup again, and you can select the rate of charge, and press setup again to exit. Once you have the battery details and charge rate done, connect the battery and hit enter, and charge mode will start. It'll beep when its done.
