What are you charging with? A wall box or a "granny charger" from a 13A socket? After you charge it, what does the charge indicator on the dashboard show? It should be reading in the high 30's up to 40 if you are lucky. How quickly is quickly? You will drain more out of the battery miles than the geographical miles, especially in winter with lights and heating on. In winter, mine drains 15miles for a 10 mile journey at night.I have just bought a 22 plate 250e plug in petrol hybrid.
Everytime I charge it up, even though I do not engage the electric engine, it drains really quickly.
Anybody help??
