    I have a 2002 330Ci and a 2005 X3, both have the original batteries in them. Amazed at this. Is this unusual? Both start fine and appear to be OK. Neither have the green light showing. I know it is best to replace them but it has become sort of a challenge to see how long they will last.

    Maybe it was a super sub-set of batteries in 2002... :<)
    My 2002 540i ran the original battery until late 2014, 83K miles.
    No battery tender, just kept on going like that silly E bunny.

    Get them load tested and then you'll know for sure.

    Ditto the load test that will tell you the health of the battery.
