No problem Nick, The settings you are talking about will be the offsets for individual cell monitoring. If you let the memory back-up battery run down or remove it all of these settings are lost.

You should have a piece of paper that came with the Pro-trak, if not there are instructions on the web site about re-calibrating the unit.

This only affects the individual cell monitoring though, for charging/dis-chaging you won't have any problems.
