The first step in reviving a 0V/low voltage battery is to use the voltmeter to verify the amount of voltage in the lifeless battery. If the battery indeed has 0V, you will see this indicated on the voltmeter. The 0V battery will also not charge when inserted into the smart charger.
However, lithium-ion cells are too sensitive to over-discharge to be recovered from 0V and used in most applications, and cannot be serviced. To recover a lead acid battery, charge it for 10-12 hours and then measure the terminal voltage. If the battery is undervolted, then try to fill each compartment with water or use a desulfation device.
In some cases and with some cell chemistries, it is possible to recover a 0v cell. Lead acid cells and battery packs can be recovered from 0V and used with almost the same performance as before. However, lithium-ion cells are too sensitive to over-discharge to be recovered from 0V and used in most applications, and cannot be serviced.

With that being said, if you are dead set on recovering a 0v cell, you can get a lithium-ion charger that features a cell recovery function. This mode will slowly wake up the cell and is basically the only safe way to do it.
Depending on how that protection circuit is designed, you can recover the battery by simply charging it. Or the protection circuit might act like a fuse and never reconnect the terminals. Professional tightwad.
Table 4: Relationship of specific gravity and temperature of deep-cycle battery Colder temperatures provide higher specific gravity readings. Inaccuracies in SG readings can also occur if the battery has stratified, meaning the concentration …
So, a lithium-ion battery pack that has a BMS may show 0V on the output even though the cells are not really at 0V. In these cases, a lithium-ion battery pack can be fully recovered from 0V by repairing or replacing the BMS …
NUE leads the development and distribution of proprietary, state-of-the-art, ruggedized mobile solar+battery generator systems and industrial lithium batteries that adapt to a diverse set of …
Can a LiFePO4 cell be recovered from 0V? I applied a constant current power supply to one of the cells at 0V by tapping into its ends directly in the exposed pack, and at …
In one case, I recovered an 8-cell (8S1P) 100Ah battery where the total pack voltage was 3.7V measured directly on the battery (yes, bypassing the BMS). Each cell was …
Battery balancing methods can be categorized into Active cell balancing and Passive cell balancing,we''ve also listed the other two, learn now ... She has been involved in …
I have a Discover AES 44-4800-3000 battery with less than 100 cycles that is showing one bad cell (0V) out of 16 (the rest are roughly 3.34V). I''ve had extensive …
Batteries discharged to 0v have irreversible damage to the chemistry in the cell. You can''t revive them to anywhere near full functionality. The are internally degraded and should be recycled.
I have successfully revived a battery from 0 volts, but the capacity was less that 50% afterwards. Better to just get a new one. I used an adjustable power supply to apply 3 volts at a low …

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 …

Sometimes yes, dead lithium-ion batteries can be revived. It depends on the cause (of battery failure). If the battery is not physically damaged, or not moisture infected, and …

The battery system, as the core energy storage device of new energy vehicles, faces increasing safety issues and threats. An accurate and robust fault diagnosis technique is …
On another note, if you measure 0V from a li-ion, it might just be that its protection circuit has disconnected it from the terminals to prevent a deep discharge. …

I bought a bunch of those K2 26650 cells that BatteryHookup had last year and out of 240 total, just one arrived at close to 0v. Was able to revive it by trickle charging with a …
