welcome back stranger (Glos Guy) i hope you and your family has kept safe and we find you in good health.
the battery wasnt to much of a surprise really as its a diesel and we do low mileage and with lock downs its only doing a couple of short journeys a week plus the A/C is on most of the time. after restarting the car with the old battery it was only holding/producing 6 volts. glad we never had to pick up the bill though.
