oxi,
I check the battery by how fast it goes down once the starter is engaged. If there is any doubt, that I get the turbine to Ng 50% I cut it, latest at 16V!!! That's your last chance to unlock the throttle.
206 procedure is to much Ng for the Arrius before lighting off.
Though it still is the old procedure, but it works better for me:
Cold start: Engage the starter and roll imediately to ground idle.
Hot start: Engage starter and roll to ground idle at Ng 10%
Charme everytime!
