Hello, I would like to install a new, stronger battery in my Fiat Stilo. Preferably from Varta, since these batteries are still obviously the best ones. Currently, a 60 Ah battery (also Varta) in my Stilo provides the electricity, but this was often a bit overburdened in the winter (too low cold current). Therefore, my question: Do you know which battery size I can build into the Fiat Stilo 1.6 16V maximum? Money doesn’t matter, I’m ready for the strongest battery, too. n highest price to pay. Thank you for your help! MfG
