Lithium-Ion 18650 Rechargeable Cell 3.7V 2200mAh (2C) Grade-A

Received in time. Product was as spec'd in site.

I am new at this, so I didn't check individual cell voltages before replacing my laptop battery. Later i found out that it is better to equalize the voltage before putting it into a pack.

Also I soldered leads to battery, which isn't recommended. The laptop reads battery capacity at approx. 3660mAh ([2 x 2200 parallel] x3), after a weeks of use. So considering it should be charged to 10% of capacity (4400*.9 =3960), plus the fact I soldered, so a bit of loss there, i think it is pretty good.

Battery seems to be doing fine.

Another big mistake i did, the cell body IS the -ve terminal and it goes all the way up to the positive side. In all videos i saw they put little round paper insulators when using flat metal strip connectors.
