Mein Auto: X5 4.4 2002
Flat Battery

Hi all I'm new here so any help would be awesome........ My 02 X5 4.4 has done 315000 kms and has a problem with the battery if I don't use it over the weekend 2days, Monday morning it's dead flat.
It's a new battery only 3mths old, has anyone else had this problem?
Cheers

Batteries are not usually maintained or charged after manufacture, and with a nominal 1% self-discharge rate, a hundred days later they are dead dead dead.

You BMW will NEVER EVER fully charge its battery 100%.

Buy a SMART-CHARGER such as recommended by BMW and charge the battery regularly and frequently.

you either have a bad cell in the new battery
...even low water will cause that
or
a power drain in the vehicle

have the battery replaced if you suspect it's just that
if...
you replaced the old battery for the same or similar reason
the suspicion would be on the vehicles electronics
