Whats the Proper Sequence Removing the Battery Terminals
i saw a similar posting in another section and maybe it helpful to post one here too.
Its been awhile since I mess with car batteries, and Im trying to recall. But maybe members can better refresh my memories, the chips are failing!
1. Do you disconnect the negative first or the positive?
2. Do I need to remember the radio code, does it even have it, where is it?
3. Whats the proper clamping procedure to jump start? Is the a special jump terminals on the car frame for jump-start?
4. and any other safety factor about batteries may be useful to the forum

As far as pulling the terminals off, Always pull the Negitive (ground) terminal off first (Unless you have a rare vehicle that is positively grounded). Then remove the positive terminal. This helps reduce several safety risks. One major one is if you remove the positive terminal first and your car has a negitive ground, if you contact any metal the wrench will short out. In my case about 22 years ago (When I didn't know all that much about cars) I did this and the battery exploded, splitting the battery open and sending acid all over. Not a fun thing.
As far as the other questions, I'm not sure of the recommended procedures for new BMWs.

BMW seems to suggest clamping in this order:
1. + of good battery
2. + of dead battery
3. - of good battery
4. - of dead battery
Then remove in opposite order.
Most places suggest the following order:
1. + of dead battery
2. + of good
3. - of good
4. - of bad
The remove in opposite order.
In both cases, remove from - terminal of dead battery first.
Also, most people will jump with the cables still attached, car with good battery still running. I read somewhere that in order to avoid the remote possibility of damaging the ?alternator of the bad battery car, you should turn off the good battery car and remove cables, then try starting the bad battery car. If that fails, then try the method most use and hope nothing shorts.
