whether my cycle count is too low?

Hi, i was wondering what is the average cycle count for a laptop battery? I have a laptop, and the batery failed at a count cycle of 200 according to my laptop software. It is a replacement i bought it online. I find that to be very low because my friend claimed that his battery from http://www.batteryselling.com gave him wll over 300 cycles. I have already done a little snooping on the Internet and read in various places. Most of them said that the normal "cycle" amount should be 300-500 cycles and it depends on the way you use it.

I am not sure if I did something wrong to make my battery go dead so fast. Can anyone recommend some other shops like laptopbatteryselling because i think the expense is too high for me.

Any thoughts?
