A car battery is only 12 volts and this is such a low voltage that it will not be able to harm you.
There are a few points more to simply disconnecting the old battery and replacing it with the new one though.
Make sure you know your car radios security pin number as if you disconnect the battery you may find the radio will not work until the pin is re entered.There is a way around this if you get some jump leads you can swap batteries around without disconnecting power from the terminals and thereby not needing to re enter the pin number.
Simply be care full and you will be fine.How do you change a battery on a Peugeot 406?
Make sure that the old and the new batteries have the positive and negative terminals in the same positions,sometimes they are on different sides. How do you change a battery on a Peugeot 406?
you cant get a shock,just make sure your ignition is off when your connecting and disconnecting and you will be fine,it can only go on one way usually,its straight forward enough,you will see,good luck..
