Dear colleagues, since my battery is probably replaced I am looking for a battery with maximum start power (at least 72 Ah) and maximum size for the C4 Grand Picasso I, 2.0 gasoline 140 HP. I have now read several times and also heard from car drivers that the C4GP basically installs too weak batteries and thus also wrongly offered by the battery manufacturers to weak batteries according to the production specifications, with Varta e.g. with 60 Ah. the Varta Silver or Blue Dynamic recommended, so from 72, 73 Ah. Maybe there are also better alternatives?What kind of battery is the best for the C4GPI 2.0 l gasoline (lead, AGM, gel)?And does anyone know the maximum dimensions that can be installed?From the power it is clear: Exide or Varta. But are there reasons for other models or do you know any other alternatives?Exide Premium Carbon Boost with 77 Ah, 760 A 76,20 €Banner POWER BULL 12V 74Ah 680 A 83,90 €BOSCH S4 008 74 Ah 680A 86,29 €Varta Silver Dynamic Ah 77 780 A 88,91 €
