850 mA , you meant, right Huh?

@gunnu, as Akhil sir said, it is normal to take that much time to charge a 4400mAh battery with B3 charger .
For fast charging you have to get a high power charger. Imax B6 being the cheapest option as of now (50W) .

if you need to charge few batteries look for 4in1 or 2in1 50-80watt charges.

Don't go for the charger from ebay.com since it is available from indian sellers at a few 100 bucks and we know it works. You can't trust those chargers from ebay at all.

http://rcmumbai.com/index.php/product/imax-b6-copy/  get this charger
