whist working on my 123 280te restoration for the last couple of years, not much has been needed on the 6.9. then on the weekend I went to start it and dead as a dodo. not even the jumper kit got it going. wiser heads suggested it wasn't the starter and could be a completely dead battery so off I went and got one. I did ask about Varta, but the guy noted Varta were now owned by Delcor anyway and made in South Korea! my battery was about 7 years old so anything is better than that. I was glad to see not rust on my battery tray underneath after I redid the engine bay a few years ago. getting the locking plate on the battery is a real bugger in the 6.9, not much room at all.
