I need to buy a battery for my nokia 2730 classic. It uses the usual BL-5C 1020 maH battery. I went to many local mobile stores, they showed me some anik, greentel, 3gpower batteries.. but couldn't give me the original ones.. I also googled a lot but found some people selling replica batteries in bd at around 200tk. which looked unrealastic to me... So anybody please help me..
