Good evening Really appreciate help. Own a Chrysler Grand Voyager CRD Ltd (2008 model). Batter completely flat and dead , needing replacement. Ordered a battery on Halfords together with fitting and despite entering registration number on their website they came with several rectangle batteries of different sizes that won't fit in the vehicle. I require an AGM battery and looking at the shape of the holder for the battery doesn't appear to be a straight rectangular shape but a more curved one. Any ideas and help would be really appreciated. Thank you so much All stay safe and well.
