Hello!! Thank you for the reply, scirocco. Our local reseller, after my question about the price of the original battery, said to me that the most recent reference, of the OEM part, as changed to 000 915 105 DE (cost = 196.8euros ≈ 160.2£) and that there is another possibility - Economy JZW 915 105 (cost = 154,98euros ≈ 126.19£). IMHO this prices are very high, and I am not willing to buy the battery from the local reseller. I can buy similar batteries, allegedly with the same specs (I am not aware of the possible difference in the quality) for something like: TUDOR Battery = 83.00euros ≈ 67.56£; DRIVER battery = 86.30euros ≈ 70.30£; KBK battery = 61.61euros ≈ 50.16£. I might buy the Tudor because is a brand well known around here and with an ok reputation, and the others two brands are completely strangers to me. Regards.
