I had purchased this Amco car battery for 4800 with 3 years warantee, exactly 17 months back, gave the bill to the dealer, who said I will check and confirm for last one week had to send him battery images bills etc multiple times, I kept the car shut for that period of time and used OLA, it seemed that AMCO and dealers are not interested in honoring their warantee commitments, purchased TATA Green for 6200, with 2+2 years warantee
