Nothing special at all. Safety says just remove the negative cable first.

Just remember this----- when dis connecting the battery or changing it---The ECM loses all the Data it has learned about fuel trims and has to "re-learn" the trims all over again--The more modded your car the longer it takes---On a basically STOCK engine the re-learning should take about 50-75 miles of normal driving in order for the ECM to learn out-------While it is the learning mode--chances are the engine will not run at it's fullest potential--this is simply the nature of a computer controlled fuel injected modern engine

Look for "Platinum" wording in description.

PS, when disconnecting/connecting cables you may hear some "clicking" noises. Perfectly normal. (Relays)

I thought the clicking noise were the tabs on the beer cans getting opened... oh well.
