A hydrogen leak and a faulty battery may postpone Monday's launch of the Challenger by up to two weeks, NASA said today. The leak, between the shuttle and its external tank, may not be serious enough to postpone the launch, but one of the satellites in the payload bay may have to have one of its batteries replaced, which would necessitate a ''stand-down.''
