How long does the battery last aft you'd cut engine?

[spidey3]

Hi

I'd get battery low warnings pretty soon after I'd cut the engine upon arrival, with the music playing- abt 5 mins. This is when say you've dropped someone off to grab something and you're waiting. It'll then last another 5mins or less before everything cuts. No lights or any other misc electrical appliances operating. Is this normal for a E92 335 N54? What's the avg battery life of this ride? Mine's 2yrs old and seems to soon to change battery?

either the battery is almost dead on retaining charges or yr alternator is not charging the battery fast enough. either way have you battery checked by those battery shop.. it is a quick process.

Thanks will do so. Sure is abnormal for the battery to be dead so soon. So what's the longest time you've had the battery running without the engine turned on just for music?
