Exide Industries — new battery dead after 1 months used.

Bought the battery around 2000 with 3years warranty, dead after 1 month's usage, already sent to service center once but returned as good and ok, and again after 2 months the battery went dead, now again resend to service centre. Hope they will replace this time. Tried using another battery and it is working fine with out any hiccups, even got my motor cycle checked and everything is working fine and ok.
