Well the original battery was 9 years old and I decided to change it as a preventative measure. At the time there was £10 between an alternative and a BMW battery so went for the BMW battery. Well its started playing up even though its only 3 years old. Doesnt last more than 4 days , somethimes less, and even after a long run , 5 minutes with the door open you get the dreaked click of death.
I have no battery drain issues that I know of and the magic eye seems to be as usefull as a chocolate tea pot to indicate the real battery health.
Its on a trickle charger now and thats helped but clearly its on its way out.
Eurocarparts, have the Bosch S 5015 for £113.87 delivered to your front door so have bought one just now.
That should solve the issue.
