Should I discharge an 18650 battery before charging it?Updated a year ago
We recommend that you NEVER fully discharge any lithium-ion batteries. By not fully discharging it, you help improve the battery life. If a lithium-ion battery is used until it is completely empty it can enter a state of deep-discharge which can prevent the battery from recharging, effectively killing the battery.
