It has a vvc manifold, and not a drop of coolant is used. It’s not juddering or anything like that. It runs beautifully, just a subtle tiny bit more cranking before it fires up from a cold engine. No fault codes and good realtime data from T4.

Will see how things go when I purchase another battery. This one only lasted 8 years

DON'T GIVE UP ON IT BEFORE YOU GIVE IT AT LEAST A 24 HOUR CHARGE.

Maybe that will work as a tonic for it. Leave it a few hours after charging for it to settle and then it will give you an accurate figure as to voltage.---

I did a 40 mile journey yesterday - should this not charge the battery up to 12.8 volts?

NO, not a chance.

For sake of argument let's say that 40 mile journey took an hour. ( @ 40 mph. )--That would equate to ONE HOUR on a charger !!!

Batteries on petrol engine cars need 24 hours on a charger.

Diesel 30 hours if in both cases the batteries start as flat ( Discharged. )

An alternator is regulated and charges a battery at roughly the same rate as a mains charger.

Example.---24 hours charge on a petrol car means driving for 24 hours at, lets say 30 mpg, at £7.00 a gallon.
Cost--£7.00 times 24 = £168.00-------Distance covered 720 miles-

Over night on a charger = £1.00 maybe.--

All that driving would give you a headache through lack of sleep.---

Hello Andy - It has a 5 year warranty - from the RAC - checked the invoice fitted 2 years ago last week - so should it be giving a resting charge of 12.1 when it so relatively new. Will try the 24 hour charge and see.

Did my post above help you at all ???



PS. 12.1 volts at rest.--Either discharged or dead.---

PPS. Your battery will only last FIVE years if it has been charged properly.---

She charged up to 12.65 at rest - smart charger then said fully charged - 4 hours later back to 12.35 volts so not holding charge -will check today again. So a duff battery or possibly the alternator not working properly

But under load the battery gave 14.1 which seems OK.
