I bought a VARTA battery here in September. First, he asked to check the charge of his battery, since the battery sat down after 50 days of standing, and the car would not start. They said that, in principle, it is still possible to travel, and if it does not start in winter, then change it. I decided to change it out of harm's way now, since I have been using this battery for 5 years, and so as not to have problems in winter. I liked that the employee did not try to sell the product by hook or by crook, but carried out a correct diagnosis.
