vehicle battery charge low

Haven't driven car for about 2 weeks and vehicle battery charge low ,came with a advisory to drive for long period , went for long drive , no more messages .
Had the car for 2 years now and it often sits idle for up 2 weeks .
First time i had warning light .
Bmw claimed battery will hold charge i think for up to 4 weeks ?
Would my trickle charger from my e92 m3 , be any good .
Any thoughts ?

With that kind of usage it does seem you are going to need a conditioner as per the one above (although they are around 100 in the UK!). I guess you may have just done a short run or two possibly at night before leaving it for 2 weeks or done something different in terms of usage? Have you got a dash cam or anything else plugged in? You should use a conditioner that is designed for lithium-ion batteries as they don't like over charging (e.g. a constant trickle is not good for them). A charger designed for li-ion will charge in a particular (and different) way to optimise the batteries life... The battery can cost nearly 1000 to replace so you want to keep it in good condition...

I thought you wanted 50

Either way put it for sale in the M5 section as it will sell plus I can add how good it is to help sell it
