battery replacement

[Tysonwills]

I have mentioned the problem before i have of the car on the ramp service light.
I think its a weak battery fault so i am going to replace the battery.
Do i really need to register it to the car and if not will the service light go out after installing the new battery

My local garage fit me a like for like battery, they linked the car to a computer (coded) the car/battery, touch wood, no problems since!
