As the battery is used, the voltage will drop lower and lower until the minimum which is around 3.0V. You should see the number 3.7V written on the battery itself somewhere. For example, here is a profile of the voltage for a ''classic'' 3.7V/4.2V battery.
The ideal voltage for a lithium-ion battery depends on its state of charge and specific chemistry. For a typical lithium-ion cell, the ideal voltage when fully charged is about 4.2V. During use, the ideal operating voltage is usually between 3.6V and 3.7V. What voltage is 50% for a lithium battery?
The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases. This voltage can tell us a lot about the battery’s state of charge (SoC) – how much energy is left in the battery. Here’s a simplified SoC chart for a typical lithium-ion battery:
Companies that make Lithium-Ion battery charger ICs say that discharging to a voltage less than about 3V causes some Lithium ions to convert into molten Lithium metal that shorts the battery. Then charging causes a high amount of heat and a fire or explosion.
While it’s not harmful to occasionally charge lithium batteries to 100%, it’s generally better for battery longevity to keep them between 20% and 80% charged. Constantly keeping a lithium battery at 100% charge can slightly reduce its lifespan over time. What voltage is 0% lithium ion?
Cut-off Voltage: This is the minimum voltage allowed during discharge, usually around 2.5V to 3.0V per cell. Going below this can damage the battery. Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries.
Lithium batteries should never be discharged below their recommended minimum voltage, as doing so can cause irreversible damage and reduce their overall capacity. The cut off voltage acts as a safety net, preventing excessive discharge that could lead to cell degradation or even failure.

The ideal voltage for a lithium-ion battery depends on its state of charge and specific chemistry. For a typical lithium-ion cell, the ideal voltage when fully charged is about 4.2V. During use, the ideal operating voltage is …
For lithium-ion batteries, the common cut-off voltage is generally: 3.0V: This is often used as a safe threshold for many consumer electronics. 2.5V: Some applications allow …
A 3.7-volt lithium battery reaches a low level when its voltage drops below approximately 3.2 to 3.4 volts. This level indicates that the battery is nearing depletion and may require recharging soon to maintain optimal performance.
Lithium batteries, specifically lithium-ion batteries, are considered ideal for all kinds of electric vehicles, marines, boats, and RV electronics. This is because of their higher energy density and higher voltages compared to conventional lead-acid batteries. When a 12V lithium battery is fully charged, it may reach a voltage of around 13.6V. Even after losing 10% …
Impact of Low Voltage: Conversely, too low a voltage level can harm battery charging and discharging efficiency, shorten its lifespan, and prevent it from functioning …
Most battery circuits stop at 2.7–3.0 V/cell. So to achieve a full state of charge you''d normally want to aim at 4.2V. In practice charging Li-Ion safely and efficiently does involve quite a few steps so you may want to look at a dedicated charger chip.
Lithium-Ion Batteries: Widely used in smartphones and laptops, these rechargeable batteries vary in voltage, often around 3.7 volts. They are prized for their high energy density and low self-discharge rate. Lead-Acid Batteries: Common in automotive applications, these batteries usually provide 12 volts. They are known for their high power and …
What voltage is too low for an AA battery? Minimum voltage, voltmeter and aging. Sep 04, 2020 Pageview：61073 . AA batteries are one of the most common types of swappable power cells in circulation today. They are what we picture when we are looking for common, replaceable batteries of classic size and shape. They are often used in single cell devices or …
Companies that make Lithium-Ion battery charger ICs say that discharging to a voltage less than about 3V causes some Lithium ions to convert into molten Lithium metal that shorts the battery. Then charging causes a high amount of heat and a fire or explosion.
$begingroup$ Yep -- for Li-Ion batteries there are three important protections: OCP (over-current protection), UVP (under-voltage protection) and OVP (over-voltage protection). OCP applies in both directions, charge and discharge, and the value at which it trips (especially charge) varies with temperature -- it''s a bad idea to charge a Li-Ion battery at a high charge …
Yes, lithium-ion cells undergo unwanted chemical reactions when discharged below 3 V, causing their internal resistance to be permanently and …
The voltage behavior under a load and charge is governed by the current flow and the internal battery resistance. A low resistance produces low fluctuation under load or charge; a high resistance causes the voltage to swing excessively. Charging and discharging agitates the battery; full voltage stabilization takes up to 24 hours. Temperature ...

Yes, lithium-ion cells undergo unwanted chemical reactions when discharged below 3 V, causing their internal resistance to be permanently and significantly raised. Their capacity will suffer as well, meaning that they won''t accept the same amount of charge anymore.

Technically the minimum amount of voltage for charging will be anything above the current state of charge. But that''s probably not the answer you''re looking for, from Lithium-ion battery on Wikipedia:. Lithium-ion is charged at approximately 4.2 ± 0.05 V/cell except for "military long life" that uses 3.92 V to extend battery life.
