Correct LiPo Charge Rate?
A nearly new Dell laptop fell from (atop?) luggage storage of a car on the highway. The device broke into pieces. Screen and housing badly fractured. What a shame. They did not slow down I rescued ...

a 14500 lithium cell has a diameter of 14 Mm and a length of 50MM
an 18650 cell is 18mm diameter and is 65mm long.
individual protection circuits add a smidge of width and a mm or 3 of length to the battery.
An appropriate charger for many tyoes of cells would be this

It has a 12vDC input as well as 120/240vAC

I have many 18650 cells i extracted from failed laptop battery packs. usually only one cell fails and takes out the to other n parallel with it. The cells I have are from 9 cll packs that cost only 22$. They are not good high capacity cells and do not retain their capacity very long.
panasonics make some of the best lithium cells.
I use my 18650s in my Headlamp and a portable USB power source, adn save my panasonic NCR18650Bs for tasks where run time is more important, the laptop extractions are just swapped out when they can no longer maintain the desired output on my nitecore HC50 headlamp, which is a 565 max lumens on Turbo, but cuts back one it gets hot or the battery cannot maintain the voltage needed to drive the cree led this hard.
