Hi all,
I started collecting cells in Mai 2018 after I understood the recycling of old Laptop Batteries.
Now I started to build my packs and I realized that the cells I tested in the early days have lost a lot of their capacity.
For example, a cell initially tested about ~1500mAh between 4.0 V to 3.5 V now has only ~1150mAh.
Is it because of aging, or what can be the reason?
When I stored them they had about 3.5 to 3.7 Volt, which they still nearly have, so they did not discharge by themself.
Does it mean, I should not let them rest for such a long period?
I don't expect them to lose their capacitiy when they are in use, especially only between 3.5 and 4.0 Volt, or do they?
regards
