Charging of 18650 cells - selection of charging mode and current

Hey,

I have a Li-Ion 18650 Sanyo link (an indefinite model - comes from a notebook demobil) with the following measured and real technical parameters:
4.22 V
Capacity. 2372 mAh
Inner resolution 87 m?

and a popular charger Lii-100 .

questions:

1. Do I really think that for this cell I should set the 3.85V mode and 500mAh current, or maybe 1A? The seller only informed me that I should use Li-Ion CC or CV 4,2V chargers .

2. Is he charging for the Lii-100 charger Xiaomi MDY-03-EB charger / plug ? If I see correctly, it fits in with the parameters listed by the manufacturer Lii-100, but also supports QuickCharge 2.0 technology - I'm not sure if it will not have any negative impact on the loading process.


I will be extremely grateful for your answer.

Greetings.

You should set the 3.7V Li-Ion mode because it charges it to the final voltage of 4.2V. The 3.85V mode will charge the battery to 4.35V, and the final voltage has very few Li-Ion batteries currently available. The 0.5 A charging current will be safer. You can try charging with 1A current, controlling the temperature of the battery, if it gets too hot, reduce the charging current.

Could you explain this phenomenon to me?

And the last question - should I unload the link to zero before charging, or simply recharge it on a regular basis as needed?

This is not a phenomenon. On the cells (some) and in the mode descriptions, the rated voltage is given, not the final charging voltage. Like a 12V car battery, it is not charged up to 12V and up to 14.4V - 14.6V.

Li-Ion cells can be charged at any time. You do not have to recharge them completely. So you can easily recharge them when it is possible. They do not have to work in cycles from full charge to full discharge.

In the meantime, I read this and that and I came to this myself, but thank you very much for your answers!
