here are my results! ill probably test more batteries in the future as im getting a mah tester. sad to see this from ifixit
you are very correct, however it is widely speculated that cycling li-ion batteries that have been in storage can essentially clean off a mineral layer that forms from nonuse, giving back a small amount of capacity. it was primarily done to ensure each battery was given the same parameters, charged to 100%, discharged to 0%, then charge back to 100% and begin testingVery interesting thank you. I do not know what you mean exactly by "cycled from 100%" but if I understand correctly you took the cells from 100% charge to 0% before testing.
My understanding is this should not be done with lithium-ion batteries since they will degrade if used at less than 20% charge. We do not need to cycle these batteries like we did with the old alkaline ones. For maximum efficiency lithium batteries should be kept between 20% and 80% of charge.
If you keep the DS on charge all of the time, then the batteries will degrade quite quickly.My understanding is this should not be done with lithium-ion batteries since they will degrade if used at less than 20% charge.
