Make things up? Really?
I left it short because there is PLENTY on this topic already.
You don't need any tests to see what I wrote.
Simply use them, and it is obvious they overstated the capacity claims. SOME will outperform a year old, abused battery, of course, because the battery is trashed. Not because the cheap battery is any good.
It has long been known that Chinese manufacturers overstate their capacity.
I have yet to buy one for the Elite, I'm waiting on Anker to put one out because the cheap Chinese batteries are only good for short term emergency use.
I have an OEM for the Optimus V and two generics. I also have two OEM and one Anker for my Evo 4g, and one oem and one Anker for my Evo V. The generics are clearly substandard while even looking at them and hold far less. I have also seen and used several Chinese notebook batteries, same thing, and they only last a year or two at best in most cases. Ask a few who have bought them, it's not like this is a secret.
However, take a look at this if you doubt it.
