1. NO WAY are you drawing 20A if the batteries are remaining at 12.6V. 12.6V is indicative of a fully charged battery...
2. Buy a voltmeter - you're going to need it in the future anyway. Clamp on ones are really useful to have so that's what I would get...
3. Disconnect all leads from each battery to test each one. (ie: remove the terminals from each battery!) How are you testing? Best (if wet cells) would be a hydrometer - another good investment (pennies).
4. Ask the previous owner if he had battery issues.
