Also, when checking battery voltage I would suggest doing it under load. The meter alone pulls minimal current and may give a false reading on the true condition. It could well read 12.6v but that might be what is called surface voltage. As soon as a load is applied the voltage might drop by several volts. Headlights alone may do it but they usually pull around l0 amps which isn't very much load. Better would be trying to crank the engine while checking the voltage. If voltage at the terminals drop more than a couple of volts suspect a discharged battery or dirty terminals. If the battery turns out to be discharged then the charging system would need some checking.

In addition to checking the charge, I would suggest removing the battery cables and cleaning the terminal posts and ends to make sure a layer of oxidation or worse, corrosion has not started on the battery terminals. In some instances and if conditions are right it does not take sitting for very long to have a dirty layer form between the terminal posts and cable ends. The layer will have a high resistance which acts exactly like you are describing.
