The battery terminals are subject to corrosion. You can't even see it because it's on a molecular level, but what is happening here is the classic "brownout" where varying amounts of power can get thru. Probably is a CLUSTER of connections at the positive terminal. Brass wire brush and use some electrical cleaner spray. Do not forget the ground lug attachment. Clean up, and all will be well with the world.
