Cost of battery, 71 UK pounds, good I felt.

I also bought a cable from to do the registration, which cost another 25 pounds.

The result was good, and the registration below was particularly interesting. It worked first time, and also explains the difference between black and white batteries (mine was white conventional lead-acid), the black ones are the glass-mat ones which are newer tech.

This is from DIS software, which is used at the BMW dealerships, so it should be the last word on whether we need registration for a new battery....

We do.

Not only that, if the battery is different, such as capacity, to the old one, then it recommends the further step of recoding as well!!!!

I haven't tried that yet but I have the Progman software working too so I might.
Can anyone tell me if this cable from does the battery registration as well as the BT cable does? What all does this cable do? It is certainly is a lot cheaper than the BT cable.
