I was hesitant to buy a car battery on the Internet. I do not regret it: I was delivered quickly (2 days I think) and, three months later, my Touran always starts like clockwork. I also used a small battery-based backup box 9v on cigarette lighter, which saved me from everything "reprogram" (only a few parameters on-board computer). Note that with the old battery Varta (8 years anyway!), The Touran was sometimes a terrible noise at startup (I felt like starting an old tractor). And curiously, never "cold". The battery had to give him the power necessary for a free startup. The only problem is we did not always "lucky" to have signs of weakness of a battery. I made recently expenses on another vehicle. If I had had time to order from you, I would have had better for less. I wrote this three months after installing your battery. 5000 km traveled in less.
