Nokia- Battery- BL-5C
New Battery not wroking properly

Dear Sir/ Madam

I purchased Nokia battery- BL-5C for my set Nokia-6600 on 9th Aug'09 from Davinder Communication, Near Laj Dharam Kanta, Sai road, Baddi, Solan, Himachal Pradesh. Owner's name of this shop is 09816402327. I have asked to give me original battery and they gave me saying that this is original and so I took cash memo also for the same. This battery after charging full, does not work for 4 hours also and gets discharged soon.

I want to have original battery of Nokia from them.
