Output when all is off is already higher I think charging battery may make a difference.

Revised measurements

Battery is now fully charged I am getting:

All off: 13.8v

Lights ON
Idle 14.1v
5000rpm 13.8v

Lights OFF
Idle 13.9v
5000rpm 13.5v

Does this seem OK or is it likely to die on me again?

Looks fine. The all off value will settle after a few hours after being switch off, so dont worry when its drops back down to 12.7 ish.
