I will be changing my battery this afternoon with a group 49 agm. I wanted to know if there is anything special I should know before removing my old one? Like will there be a radio security code? Sorry for the stupid question but I'm coming from vw/audi and all my previous cars once battery is unplugged you need a radio code to unlock it, not sure if Volvo is the same. It a an 07 VR by the way.
Thanks in advance

Cool, thanks :) it doesnt mention the positive though. I guess I remove the negative and then the pos. Or pos then negative?

Always remove the negative first. That way if your wrench comes into contact with the body you won't have a welding/battery explosion event.

yes, negative first, and, in our 06 v70 the radio code is in the computer, but the time i have had to reset.

good luck and good choice of 49/h8 size, i did it too, much better staying power.

VR is H8 by default. Probably why it lasts so long lol.

So i followed the advice I got here and everything went great :) car cranks and starts faster than ever before. So far I'm glad I went with the bigger battery. And thank you for all the tips
