The general maintenance of electronic gears is very similar to that of their cable counterpart. However the main difference is that as with most electronic/mechanical systems firmware updates are required to keep the product in tip-top condition. If this is not done the new components added to the system due to breakage or failure may have incompatible firmware and this may cause poor gear changing, battery fast discharge and other issues.
