Battery defective after 2 years and 1 month

Hello, I am very disappointed by Suzuki. At our Suzuki it turned out that the battery was apparently empty (were on holiday and the car was 2 weeks in the garage). When checking in the workshop it turned out that the battery is defective and this after the 2 years. Suzuki does not show itself kulant and said that the battery manufacturer gives only 2 years warranty. Has someone experienced a similar thing. I have not experienced anything like this from any of my previous vehicles. Suzuki SX4 year 6/2012
