12 days since my 66 Cooper S was delivered (bought long distance) and I've had enough! I am going to reject it, but suspect it will be a hassle.

Battery was completely flat the day after it arrived. Organised Halfords to deliver and fit a new one - AGM096 (as shown on their website - and everyone elses), but when he took the old one out, the 096 was obviously too small. He said the size was a 115, but their system showed it as "not suitable for this vehicle". Spoke to a Mini dealership - they only recommended fitting a genuine BMW battery (which measured the same as the 115) but I had no means of getting the car there. After endless phone calls, the dealer from whom I bought it instructed the AA to come and fit a 115, which they did. The guy did say "odd, as our system says an 096".

Today I went to take the car out, but the "emissions" light has come on permanently, and the Start/stop is shown as inoperative. Took it for a short drive, and was fine - but the light remained on. I have a sneaky feeling this might be linked to the new battery.

There must be thousands of batteries changed every year on these cars - how come there is such confusion?

A quick search online for me shows both types pretty much equally, so I am guessing that a different spec could dictate which it is, but obviously that is a guess.

On the subject of the start/stop & EML issues, the vast majority of cars need to be told that they have a new battery fitted and they then re-learn its capacity/state of charge etc otherwise they still think they have a stuffed battery.

On top of that "completely flat" can also cause similar issues, so you need to get the car/battery coded correctly.

As you quite correctly point out batteries are changed every day by the dozen & you would think by now somewhere as big as Halfrauds would be teaching their chimps how to do this.

Thanks for the reply. The dealer has accepted rejection, but has persuaded me to take it for a diagnostic locally tomorrow before they collect it (they organised it), so we'll see!
