I seem to remember when the last new battery was fitted approx 5 years ago to my 2016 model it had to be a specific size for length and height. I now need another one and can anyone tell me what the correct dimensions are in metric, the most important one being height, is it 175 or 190 mm. The last time the mechanic couldn't shut the bonnet but eventually found a battery to fit. Secondly can I just remove the old battery and install the new one, just like the old days?
