Hi, a while back my mechanic informed me that my engine battery was on it's way out. I was hoping to get through the winter before replacing it but no joy. I have had a look at it and I cannot find any markings, Ah or anything on it. It is for a Peugeot Boxer 2.0 HDi 2003. Any pointers would be appreciated. I have also had a look in the handbook without success.
