Just so you are aware Carly does NOT correctly register batteries. It says it did but if you connect another type of scan tool to read the status of the battery, no such register happened.

Very well written thanks for the post. Considered an ICarly but heard they were not as good as people made out to be... Was thinking of getting a ThinkDiag 2

I have another battery registration tool on my laptop. I will give it a try and see if Carly really did register the new battery. Carly would not register a new battery in my 128i.

Thank you for the detailed guide. I'm going to replace the battery next week.
