		The battery warning light just came on in my D4, and stays on when ignition is off. The car is exactly 3 years old.
I was wondering if this is reasonable for a D4 battery to last, or whether my recent install of a CB radio wired directly to the battery might be draining the battery (although the CB has been kept off and unused for all this time)? I just don't want to go replacing the battery if the underlying cause is something else (ie the C.
I know this is somewhat of a "how long is a piece of string" and also a "your milage may vary" issue, but still interested in your experiences. The car is used daily for city use and many short (<10km) trips a day. Longer trips on weekends.
I will also try charging it up with a battery charger and seeing how long it will last.

Interestingly they replaced with a AGM battery rather than the original Calcium Battery.
Mine was one of the first of the D4's......December 2009.
Had to replace the battery at around 83,000 Klm's.
