My 2012 Transit runs well but the starter response is less than lively the engine turns over sluggishly as thought the battery is almost flat in everyday running the only problem is it sounds wrong. its obviously charging to some extent because it doesn't get any worse. But equally after a 300 mile trip it isn't any better. I've bought the stuff to fit a leisure battery but haven't fitted anything yet as my instincts tell me there isn't charge enough coming out to charge one properly never mind 2. A month ago I had a new top quality battery fitted. has any body got any suggestions. Thanking you in advance
