Cheap imitated Made in China cells

I buy those cells from some local stall, rechargeable AA size Ni-MH fake Sony brand. I know it wasn't original since it is very cheap around RM4 each piece. Initially I use it only for my wireless mouse, but I found it just perform like a 3-4 years rechargeable battery that use in my mouse. Seem like this cell only suitable to be use in clock only, therefore I decided to open it out and see what happen. Picture below show a piece cracked by me and another piece is the look before it was cracked.The picture below show the true cell part of the cell. However, it is only about 3cm height and not in high density too.
You know what I found at the bottom of the cell? A dummy weight make by cement, this is the trick of the seller to convince those buyer to buy their battery.

And it label a 4000mAH capacity! Honestly, a single cell don't reach 4000mAH. The highest in the market now only 2600mAH for AA size.

The is the clear look of how the thing arrange in a cell.

Whatever manufacturing technique go to China, there are always some business man try to make it cheaper. Demand and supply, there are many poor man in China, thing must be cheap so that they capable to purchase. But honestly, I doubt if poor people want cheap and low quality stuff? I certainly don't buy this for real usage, just to see what they have up to.

And also, one more event that I remember is my friend buy a labeled USB2.0 hub for RM5 in a computer shop, even it is USB1.0 also never mind as long as it work. However, when he ask for my help to see why the hub just don't work, I open the hub housing and notice that there are no chip inside at all! All there have inside is a USB wire that split it connection to four connector, can this kind of device work as a hub?

As more people want thing to be cheaper, the market create some demand, there are supply. What can we do? The cheapest survive?

Attn: Don't open a battery cells to inspect what is inside, if you want to do so, make sure that you do in a place with good air circulation. Don't attempt to breath in the vaporization from a cell, as it will poisoning your lung.

How I hope Malaysian can developed a better way to dispose off our used battery cells to reduce environment pollution.
