I have purchased amaron battery some time during september in mangalore, karnataka, (Amaron black caa4330p114759 - aam-bl-0bl400rmf). Now the battery is completely dead while i visited amaron centre in mangalore he is refused to replace the batter for the reason not having guarantee card.
When i purchased the batter the dealer did not issue any card and advised me that the bar code is enough extract all details.
