Rechargeable Battery 1.2V AA NI CD 1800mAH (pack of 4)

After receiving the batteries, I got suspected about the quality when i found the weight of batteries was abnormally low. In some hope, I still gave it a try. It lasted for only 4 mins after immediate full charge while using it in trimmer. My older dead cell with 450 mAh was running for 6 minutes! Then i used it in a mouse. To my surprise, it couldn't work even for 1 day even mouse which is one of the least power consuming device.I immediately wanted to return these batteries as it was just waste of money but couldn't do as original package was disposed. So left option was only to throw these cells in dust bin. I had to scrap them on 2nd day of purchase. It is just unbelievable how Amazon can allow such fake products to sell on its platform. They are certainly hollow cylinders and not 1800mAh cells.
