After doing a lot of researches, confusions and searches, i finally came to a conclusion of buying Sanyo Eneloop batteries for my Canon powershot camara. But now another problem arised. From internet search i almost came to know that Eneloop 2700mah or any eneloop batteries are not available in CHENNAI at all..!! Is wat i say is this true..?? If i am wrong, go ahead and tell me where can find Sanyo Eneloop NiMH 2700mah AA Batteries in Chennai? Place or shop or mall. (i am indicating Chennai strongly because i live here). Let me tell u that i am NOT interested to buy via online like amazon or ebay India or from any other part/city of India or even abroad. (its just for my satisfaction and to avoid getting a fake once). I need to go and buy myself. I have some Additional question, here they are- 1) If I dont find Sanyo eneloops, what are the best next options? the other options/branded batteries should have characteristic similar to eneloops. In most of the shops i find Sony, Sanyo (normal 2700), eveready and kodak. (i guess uniross, energizers, duracel, hybrid, Olympus, etc are not available in chennai) U can also tell the best from any of these above i have mentioned above are if available in Chennai. 2) How to exactly find/know a difference between Original and duplicate AA rechargeable batteries? (i recently saw a 2 Sanyo 2700mah ReCh Battery pack near my house for Rs.350 and doubt that they are fake. but are they exactly?). How to??? 3) And i recently heard about Li-ion AA rechargeable batteries and USBCELL AA rechargeable Batteries (not extra charger need, having inbuilt USB charger to charge them from Laptops) too.. Are these available in Chennai?? if yes, wat is the cost and wer in Chennai are these available (both)? Thanks in Advance.... :)
