Howard,
thanks...I possibly need to use the Optimate more.
At 12.3v the car starts without any issue. I wonder how low it has to fall before the car will not start?
It's not just poor starting that tells you the battery charge is slightly below par. On my Aero, some of the CANBUS sensors seem very sensitive to voltage differences, for example bulb fail warnings. The lights work OK, but warnings are triggered unless the battery is fully charged. Quirky things these Morgans.
