Exide Excell 12v Car Battery Megane, Focus, Corsa, Fiesta, *

I bought this battery 6 months ago thinking a problem I had with my car was a battery one, turns out it wasnt after fitting so has been sat in the garage ever since. Good quality battery with receipt and never used except to test car once. Please see and check specs below. I bought this for a megane 1.5dci so will fit many others of similar and lower requirements.
