Advice please.
went out to go to work this morning, and the battery was almost dead, the central locking barely opened the locks. Luckily I was on a hill so bump started. Half and hour drive to work, and there is a charge in the battery now, dash lights bright again etc. The condition window on the battery is black (requires recharge). Is the battery finished, or can it be topped up with sterile water to bring back to life. Is it worth contacting the AA to let them test it?

If the battery indicator is black then the battery is finished and you need a new one. If it is yellow you can re-charge it, but not when it's black.

Andrew,
thats weird the label on the battery definitely says if black it has insufficient charge, yellow replace battery. Oddly its been fine since then, but I have been careful with heating blowers and air-con. Will be going for a short journey tonight with lights on, will see what happens in the morning. There is actually some useful info on this within the sticky for 5-series, which tells you how to top up with battery fluid, may give this a try at the weekend. Pete |

Yup I was talking complete tosh. It is the otherway rounds. Black and the battery is in need of a re-charge. Yellow it's goosed. Sorry, you are spot on.
