Can You Overcharge A Lithium Battery? Let''s Find Out
As the perfect technology for batteries has not been invented yet, batteries have to lose charge. Lithium-ion batteries are no exception to the case. Although, they have a lower discharge rate than their counterparts. Usually, these batteries have a self-discharge rate of around 5%. As the age increase, the discharge rate will also go up.

Overdischarging Lithium-Ion Batteries
The battery system is discharged at a constant power of 15 kW. After about 62 min, the power diminishes due to loss of voltage, and the maximum possible discharging current through the load is reached (55 A). After 66 min, the current also decreases because the battery system cannot deliver higher current due to the lack of missing energy.

What happens if a battery is deeply discharged?
“If a battery does become deeply discharged, special care must be taken during the subsequent recharge. With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke.
Why is it bad to fully discharge a lithium ion battery?
Part 3. Why is it bad to fully discharge a lithium-ion battery? Fully discharging a lithium-ion battery can harm it for a variety of reasons: Voltage drops below safe levels: Lithium-ion batteries have a safe operating voltage range, typically between 3.0V and 4.2V per cell.
Do lithium ion batteries need to be fully discharged?
The memory effect occurs when a battery “remembers” a smaller capacity due to repeated partial discharges. Since lithium-ion batteries don’t experience this issue, there’s no need to fully discharge them before recharging. Part 6. Can a fully discharged lithium-ion battery be revived?
Is it safe to fully discharge a battery?
First you say "no, [not] at all" — it's never safe to fully discharge. Then you go on to state that problems happen "during charging" — which is a different activity. Finally you claim that a "deeply discharged battery have higher self-discharge", which at this point even my uneducated brain has to rule out as just plain illogical.
Can a fully discharged lithium-ion battery be revived?
In some cases, a fully discharged lithium-ion battery can be revived, depending on how long it has been in that state. Here’s what you can do: Check for safety features: Many lithium-ion batteries have built-in protection circuits that prevent over-discharge. If the battery is “dead,” it might simply be in a protected state.
Can a Li-ion battery be discharged deeply?
No, it is not OK to have a Li-Ion deeply discharged at all. Here is why: When discharged below its safe low voltage (exact number different between manufacturers) some of the copper in the anode copper current collector (a part of the battery) can dissolve into the electrolyte.
