The life of lithium battery is generally 300-500 charging cycles. Assuming that the amount of electricity provided by a complete discharge is Q, if the decrease of the amount of electricity after each charging cycle is not considered, the lithium battery can provide or ...
For example, if you have a lithium battery with 100 Ah of usable capacity and you use 40 Ah then you would say that the battery has a depth of discharge of 40 / 100 = 40%. The corollary to battery depth of discharge is the battery state of charge (SOC).
The depth of discharge (DOD) refers to the percentage of a battery''s capacity that has been used before recharging it. Shallow discharges, where the battery is not fully drained, are less stressful on lithium batteries and can help prolong their lifespan.

For example, if a lithium-ion battery has a capacity of 100 ampere-hours (Ah), discharging it to 80% of its capacity and then recharging it would be considered a shallow discharge. On the other hand, discharging it to 20% or less of its capacity before recharging would be considered a deep discharge.
