Clean the battery terminals and cable ends. If the cables don't clamp on tightly they may need to be replaced.

Might be time for a new battery if the cables check out.

Also, check the alternator. It could be dead. Should be putting out 14.5 volts, or so. I think the battery's just not getting charged.
