Please do not overdischarge the battery, otherwise the capacity will fail.
If you do not use it for a long time, we recommend that you keep it fully charged and charge it every six months.

Lithium Ion Battery: it is a kind secondary battery( rechargeable battery), it mainly depends on lithium ion move between the positive and negative poles to work. During the charging and discharging process, Li + is in two electrode round-trip embedding and de-embedding: when charging, Li + is de-embedded from the positive electrode, embedded into the negative electrode through electrolyte, and the negative electrode is in a lithium-rich state; When discharging, it is opposite.
