I want file a complaint against amaron battery. I am using amaron battery for my car. I installed new battery last year, unfortunately that battery is not working and I contact amaron customer Care but as per the information from them warranty is valid only if I provide the warranty card. I lost the warranty card of the battery I told them about this. After hearing this they refused to give service or replacement for the battery under warranty just because I lost my warranty card. But it is clearly mentioned in the battery that the warranty is valid. Manufacturing date is printed by the company itself.
