It sounds like you have a poor electrical connection with the starting system. Inspect the battery terminal clamps and make sure they're tight, you should not be able to move them. Make sure there is no corrosion on the battery terminals and that the corrosion hasn't eaten away at the clamps. I would start here first.
Do you mean the new battery drains?
Do you have a voltmeter to do some electrical measurements?
