Understanding When a 12V Battery Is Considered Dead
Key Voltage Levels to Monitor. 12.7 volts or higher: A fully charged 12V battery typically measures at least 12.7 volts when not under load. This is the ideal state, indicating that the battery is ready to deliver full power. 12.1 – 12.4 volts: When the voltage drops to this range, the battery is partially discharged. At 12.4 volts, the

Is it normal for a lithium ion battery to read with a very low voltage
DO NOT DO THIS WITH BATTERIES THAT ARE OBVIOUSLY IN BAD SHAPE (leaking, built-up gas, damaged) I am talking about small batteries - that is where I have experience. If the battery voltage is not increasing rapidly, the battery is dead. Which means it should go from close to 0V to 0.5/0.8V in just a few minutes (measured when it is not charging).

Is draining a Li-Ion to 2.5 V harmful to a Li-ion cell?
The discharge voltage level depends on the cell chemistry. The minimum discharge voltage varies between various sites, datasheets, etc. but 3.0 V - 2.7 V is an empirical value. If discharged under this voltage, the cell may be permanently damaged. To get the precise value of min discharge voltage, consult the datasheet of your cell.

If they are LFP, they will charge up to 3.6V. If it''s listed as 14.4v, it should charge up to 16.8V, and that is where you will get around the full capacity of the battery. But you won''t get the maximum lifespan of the battery. To increase lifespan, you need to decrease the max voltage to 16.0-16.4v to get more uses out of the battery.

How to recover a lithium-ion battery pack from 0V?
If there are undervoltage cells, open the battery caps and fill each compartment with water to optimum levels or electrically add a desulfation device. When it comes to recovering a lithium-ion battery pack from 0V, the first thing to check is if the BMS BMS has tripped or failed.
What causes low voltage in a lithium battery?
Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous. Root cause 2: Uneven current.
How to fix lithium ion battery cells?
Another way to fix Lithium-ion battery cells is by voltage applying method to activate the battery. This step involves providing a small amount of voltage to the battery using an adjustable power supply. This is similar to the ‘jump-starting’ capability of batteries.
Can a PSU charge a battery up to 2V?
If you want to charge the batteries up to 2V, maybe set the voltage to 2V then so it stops the current once it reaches those 2V. Be wary though: if the battery voltage recovers on its own to higher than the set voltage, the PSU will be forced to sink current, which most don't support.
What happens if battery voltage is below 2V?
If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected. Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous.
Can You recover a lithium ion battery from zero volts?
Recovering a Lithium-Ion battery cell from zero volts is not recommended, as it can result in a fire. This is because once the cell goes under about 2.5 or 2.6 volts, a chemical reaction occurs inside the cell that permanently damages it and drastically increases its internal resistance.
