You can safely discharge a lithium-ion battery by following proper guidelines to minimize risks, including avoiding deep discharges, controlling temperature, and using appropriate charging practices. Avoid deep discharges: Lithium-ion batteries should not be fully discharged below 20%.
You should not completely discharge a lithium-ion battery. Fully discharging may harm its lifespan and performance. Keep the charge range between 10% and 90%. For optimal storage, maintain a charge level between 40% and 60%. Avoid excessive charging or discharging to ensure safety and efficiency.
When charging the lithium battery, a dedicated constant current and constant voltage charger should be used. After constant current charging, the lithium battery voltage reaches 4.2V, then it is switched to the constant voltage charging mode; when the constant voltage charging current is reduced to 100mA, The charging should be stopped.
These signs highlight the importance of monitoring battery levels to prolong the lifespan of lithium-ion batteries. Regular maintenance and timely charging can prevent complete discharge and potential damage. You should not completely discharge a lithium-ion battery. Fully discharging may harm its lifespan and performance.
The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery's lifespan.

Goal: I want to discharge a lithium cell from nominal voltage of 3.7V to 0V. Essentially, I want to build a discharge circuit without a cut-off voltage for discharge protection. I am aware, that this will irreversibly damage the cell.
After 3 years of researching how to extend lithium battery, I found that the depth of discharge is a myth, it has zero effect on life, you can discharge up to 2.75 volts without wear and tear, a smartphone turns off when it is at 3.5 volts. what wears out is charging at high voltages. every 0.10 volts doubles the cycles, if charging up to 4.20
Lithium Battery Cycle Life vs. Depth Of Discharge. Most lead-acid batteries experience significantly reduced cycle life if they are discharged below 50% DOD. LiFePO4 batteries can be continually discharged to 100% DOD and there is no long-term effect. However, we recommend you only discharge down to 80% to maintain battery life. Lithium Battery
How Often Do You Need to Discharge a Lithium-Ion Battery? Unlike older battery technologies, such as nickel-cadmium (NiCad) batteries, lithium-ion batteries do not need to be fully discharged before recharging. In fact, it is recommended to avoid fully discharging a lithium-ion battery whenever possible, as this can reduce its overall lifespan.
