IIRC, 12.3V for a battery "at rest" (i.e., no load) indicates a 50% charge.
A fully charged battery should read 12.6V when at rest.

Cheers,

Jeff

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.
