chris:

12.3 V is fine for a battery not under load. a battery can be well charged, as indicated both by voltage across terminals and hydrometer test, and yet be bad due to an excessive internal resistance, which becomes evident under a heavy load, such as cranking.

a 10 ohm resistance across meter test leads in and of itself would be irrelevant for voltage measurement because the input impedence of a good voltmeter is thousands of times bigger.
