I''ve got a box full of salvaged 18650 Li-Ion batteries that test at 0v to 0.1v and I''ve come across some videos on Youtube of people using a bench power supply to revive them by running them through their preconditioning phase. Essentially, they run 10 mA or so into the battery until the voltage on the power supply goes up to 1.5v or 2v but ...
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries. The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases.
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.
A 12v Battery Pack was at 0V and wouldn't take a charge. Manufacturer Miady recommended starting up the sleeping BMS with a 9-volt battery across the terminals. I tried this -- it worked! Battery read just over 10V on voltmeter. Immediately connected to charger.
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. Due to contact resistance or detection of charge, the current is inconsistent caused by the uneven charge of the cell.
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.

24V Lithium Battery Charging Voltage: A 24V lithium-ion or LiFePO4 battery pack typically requires a charging voltage within the range of about 29-30 volts. Specialized chargers designed for multi-cell configurations should be considered, and adherence to manufacturer guidelines is crucial for safe and efficient charging.
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.
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.
If it is the battery cell that causes the lithium battery pack to fail to charge, there are two ways to judge: One is to charge each string of cells in the lithium battery pack. If there is a string of cells that cannot be charged, it means that the cells of the lithium battery pack are faulty, and it is determined to ask the lithium battery ...

For lithium-ion batteries, specifically lithium iron phosphate (LiFePO4), the article highlights their safety, longevity, and minimal maintenance requirements. The voltage chart for a 12V LiFePO4 battery is compared to lead-acid batteries, showing different voltage levels at various charge states.
A battery maintained at healthy voltage levels can last years longer than one that is regularly allowed to discharge deeply. Inability to hold charge: A battery that has been allowed to drop below 10.5 volts may struggle to hold a charge even when recharged. This is because deep discharges can damage the battery''s internal chemistry, making ...
The phosphate-based lithium-ion has a nominal cell voltage of 3.20V and 3.30V; lithium-titanate is 2.40V. This voltage difference makes these chemistries incompatible with regular Li-ion in terms of cell count and charging algorithm. Last Updated: 25-Oct-2021.
