    Hi there. Well was out of town for 2weeks and my E46 325 Ci's battery was flat upon returning home. Any suggestions for a maintenance charger? Should I be using one most of the time?

    2 weeks shouldn't have been a problem unless the battery was over 4 years old.

    Ditto that - Deltran makes the Battery Tender, there are others on the market also - had a collector friend relay over time trickle/smart chargers end up depleting the battery as well, since they are cycling the battery, albeit nominally - so the answer to most of the time would be use it when you need to, but realistically for most of us most of the time will be fine.
