Question about BMW 530
Enough power to run the lights and radio is not necessarily enough power to crank the engine over. You did not mention the year, but on a 530, if this is your original battery, you are probably due for a new battery. I suggest that you borrow another car and attach it to the jumper cable connections under the hood (key in Off position on both cars) to keep your 530 computers powered up while you replace the battery. It is not critical to do this on a 530 as it is on the newer generation BMWs, but it is not a bad idea.
Unless there are a LOT of BMWs where you live, the group 94 battery size will be hard to find, and when you find one, it may be quite stale from sitting on the shelf half-charged for months. Most of us choose a smaller, group 48 battery. You have to put a spacer under the battery clamp, but it is a common size so it will be fresh and it will cost less.
If you really want the larger size, a group 49 'should' fit in the hole and is a little more popular than a group 94. It will be tight.
