Hi All
Well here we are again in the beginnings of the cold weather.
Symptoms:
Does anyone know the minimum voltage requirement for the ECU/BCU/ its brown-out voltage?
Checked battery voltage after 12 hour standing 12.5v = approx 90% charged.
Drop tested battery and it passes (only just) - almost hits the 'weak' area.
Second crank (successful start - I missed the first crank which was also 'annoyingly' successful this morning) battery voltage measured using DVM at interior light (without bulb) dropped to 10.3V - see here: Landrover Discovery 2 - Cold Start - YouTube
Removed and charged batt overnight - started fine the following day. Batt nice and warm as at house temperature.
No starting problems all year until now.
Batt just within (I hope) 2 year warrantee - Lyon Batt 664 from Eurocarparts
Is it time for a new one - maybe something with high CCA like the C31-1000 Numax? C31-1000 Numax Car Battery 12V 120Ah - Car Batteries - Numax Car Batteries
Any thoughts welcomed.

Well here we are again in the beginnings of the cold weather.
Symptoms:
- On the odd very cold morning she fails to crank on the first attempt (normally if car hasn't run the previous day).
- Glow light takes a little longer (5 seconds) to go out - this is expected.
- Dash board lights go crazy on first start attempt - suspect under voltage.
- Wait a while, try again and often still fails to crank again.
- Wait another 5 mins, third time lucky, cranks and starts fine.
