battery date: 2018, cells: LGABHE21865 2500mAh, same for 2019

 

I've repaired couple of 5Ah batterys. Broken case, problems with PCB, but main problem is cell dying.

Example battery from 2018 - 1 pair lost (0,5-0,6V). Battery looks like new and it is done.

Other battery 2014 stil live (4,0Ah). Maybe it depends on how it was used, charged. But I see more and more 2018 batterys with dead pair of cells inside.
