Finally results of the HP battery test

The HP battery was tested in electromagnetic laboratory.

Original HP battery (blue ellipse) and onestockusa replacement are presented in Picture 1. below.

Picture 1. Comparison of original and replacement battery.

HP original battery is manufactured in a quality way. (Although the cells are poor, that is why
I have to replace the original).

Each cell is 3.6V, and there are 3 pairs of cells connected in series, resulting with 3x3.6=10.8V voltage.

Voltage was measured on onestockusa replacement  battery with multimeter on each pair of cells.

The measured voltages on cells was:

1. 2 V on first pair
2. 1.2 V on second pair
3. 0.6V on third pair

Total voltage was less than 4V, and minimum voltage for battery to work properly is about 9V.

Picture 2. Measured voltage on the first pair of cells less then 2V.

The far worse part is that contacts on the replacement battery are very poorly manufactured.

That fact can result in overheating and consequentially fireworks.

Think twice before purchasing this onestockusa crap.!!!
