OK, had my Omega for one week so far. Had a few niggles with the alarm going off when the engine was started, doors unlocking themselves immediately after being locked and slow cranking when starting the engine.
I have just measured the battery voltage 10.5 volts
(but the good news is that when the engine is started it goes straight up to 14.3v and stays at 14v with everything electrical switched on
).
I think the battery is the original, (so 6 years old) markings are:
Vauxhall 12 01 264 EP
12v 66Ah 300A(DIN) DF
Maintenance Free Wartungsfrei
Does anyone have any strong opinions on different brands of maintenance free batteries? If I had a trade card I would go & buy a genuine battery tomorrow. Can anyone tell me what the price for a genuine battery is from Vauxhall?
