What is the DOD of lithium-ion batteries?

[cindy]

The DOD (Depth of Discharge) of a lithium-ion battery refers to the percentage of its total capacity that has been discharged. For example, if a lithium-ion battery has a total capacity of 1000mAh and it has discharged 500mAh, its DOD would be 50%.

The recommended DOD for lithium-ion batteries varies depending on the specific chemistry and design of the battery, but generally, it is recommended to keep the DOD between 20% to 80%. Discharging a lithium-ion battery below 20% DOD or over 80% DOD can reduce its lifespan and performance.

It’s important to note that the DOD of a lithium-ion battery can also depend on the application in which it’s being used. For example, in some cases, it may be necessary to discharge the battery to a lower DOD in order to meet the power demands of a particular device or application.
