Double check connections for corrosion/tightness. Another left field possibility could be the stater brushes, not hard to check but it calls for pulling the starter which calls for draining the oil. A quick check is using jumper cables connected to a car battery (non-started vehicle) If these check out then the culprit is the battery, but I'm more inclined to think connections.
