For common problems with lithium-ion batteries, we can usually determine the health of the battery by measuring its voltage and inspecting the battery temperature. Please refer to the troubleshooting steps corresponding to each specific problem for more details. How to Troubleshoot Lithium-ion Batteries?
On lithium cells, you will get metallic lithium plating out of the electrolyte when the cell voltage is above 4.3V. Metallic lithium can catch on fire when exposed to (the moisture in) the air. In Lead-Acid batteries, you will begin to electrolyze the electrolyte, causing the battery to vent hydrogen and oxygen. This is EXTREMELY EXPLOSIVE.
Applying a high voltage to the cell causes enough current to flow that the dendrite fuses and melts, and therefore, the cell is not longer internally shorted, and can hold a charge. (This is what the guy in avra's response was doing to the batteries)
Low temperature also causes lithium plating due to non-uniformities occurring within the cell elements originating from the manufacturing defects or misuse of the cell. Over-discharge is when voltage is drained from the battery cell to below two volts.
The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure. When the current is in excess, the excessive joules will initiate more heat into the cell, causing overheating. The overheating leads to increased cell temperature hence failure.

$begingroup$ I have read many times that when a lithium ion discharges too much it will trip the charge control circuit and it will not accept a new charge as the charge controller is no allowing current. When pulsed with a high voltage in this state a small amount of trickle allows the charge controller to reset and allow charge. I read an ...
If the voltage were high enough, the battery would receive a charge, regardless of the amount of current. That''s how trickle chargers work. You can buy ones that go as low as 0.75A, yet they still charge a battery because they are outputting 14+ volts. It''s the voltage that forces the current to flow in a certain direction, from high voltage to ...

For example, a 3-cell lithium-ion battery pack has a nominal voltage of around 11.1 to 11.4 volts, and a 4-cell lithium-ion battery pack has a nominal voltage of around 14.4 to 14.8 volts. Known for their stability, safety, and extended cycle life, LiFePO4 batteries provide a …
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 …
When the lithium battery is used in PACK, it is more likely to over-charge and over-discharge, which is caused by the consistency difference of the cell. If the charging and discharging process is not properly controlled, it will be further increased, resulting in the phenomenon of over-charging and over-discharging of part of the cell.

When we refer to the nominal voltage of a lithium battery, we are essentially discussing its average or standard operating voltage. For a 3.7V lithium battery, this represents the typical voltage level at which the battery operates during its discharge cycle. It is important to note that while the nominal voltage is labeled as 3.7V, the actual ...

(If I stop too soon, the voltage shoots back up to 29.35, and the voltage alarm goes off and the scooter disables.) It appears the motor controller has a particularly sensitive upper voltage range, since the SLA batteries do read around 29.3V after a full charge, but the 29.35V is enough to cause it to decide the voltage is out of range.
