Default Precautions when Changing Battery ?

Probably its just a dead battery. I got my battery disconnected from the car right now, trying to see if it will take a charge.
Just thought it would be prudent to check with the forum if there are any particular precautions to take when connecting a battery. ( i.e a little concerned about buggering any of the electronics) ???

I tied to start it up yesterday, and battery was half dead, would not start. I saw a warning "hatch ajar", but figured the battery should be able to run the bulb in the trunk for a day or two without problems. I closed the trunk and took my other car to my appointment, and when I got back, electrics were totally dead. Strange that it discharged on its own.

Negative off first, back on last. Shouldn't have any issues.

I took my battery in and out like 10 times when I was trying to get my ISF steering ECU working.
