Why is the Galaxy battery 1500mA on Ebay?

I just recently bought a Galaxy S (not S2) from T-mobile. It came with a 1650mA battery. I wanted to buy a backup battery from Ebay, and I noted ALL the Galaxy S batteries are 1500mA. (The S2 batteries are 1650). I am a bit confused as to why the Ebay batteries aren't also 1650mA like the one that came with my phone.

There are many sellers presumably selling from many manufacturers
