Customer ServiceIf your battery feels hot to the touch, it may be time to check its voltage. Another symptom of an overcharged battery is a voltage reading that is too high. A fully charged battery should have a voltage reading of around 12.6 volts. If your battery''s voltage reading is higher than this, it may be overcharged. Causes of Battery Overcharging
Customer ServiceThe voltage range of NCM + LMO/Li coin cells was 2.7–4.3 V, while that of graphite/Li coin cells was 0.01–2.0 V. Then, the cathodes (anodes) were then overcharged (over-discharged) to different SOC at 0.133 mA·cm 2 and disassembled in the glove box to obtained the overcharge electrodes.
Customer ServiceThe overcharge power input is the product of battery overcharge voltage and overcharge current (P = E oc × I oc). The overcharge voltage of the battery, within cell specification overcharge limits, is typically 1.45 volts per cell. The overcharge power input to a battery is thus:

Customer ServiceIt will be too big, so the meter will show "overload" and its next reading will try to display 230V on the 0-2.999V range. That won''t work either, so the meter will show "Overload" and switch to the 0-29.99V range. Again, "Overload", but then it will switch to the 0-299.9V range. That reading will be within bounds, so the meter will display it.

Customer ServiceOvercharge is the normal continued application of charging current to a battery after the battery has reached its maximum state of charge. It impacts the steady-state values of pressure, temperature, and voltage.
Major challenges to both the battery and the system it powers can be the result of deviations from this range, either too high (overvoltage) or too low (undervoltage). During charging or the system’s break down, the condition of overvoltage arises in which the battery accepts more energy than its capacity.
The voltage can go below the safe limit when the battery’s SOC reduces significantly. This condition can lead to the process of deep discharge in which a huge reduction in battery capacity occurs due to the irreversible formation of particular compounds.
Excessive Current and Potential Hazards Overvoltage charging, a scenario where the charging voltage exceeds the battery’s designed limit, can lead to an influx of excessive current. This surge not only poses a risk of physical damage to the battery but also increases the likelihood of catastrophic failures, including explosions.
In the standards or regulations, the overcharge performance of single lithium-ion battery is evaluated through several overcharge tests, during which a controlled current is applied to the tested battery (e.g. 1/3 C) up to a set of charge limits (e.g. 2.0 SOC, 1.5 times the upper cut-off voltage).
Due to the inconsistencies among cells within the battery pack and the potential faults in battery management system, intermittent overcharging occurs during the long-term operation of cells. However, the impact of such occurrences on battery capacity and reliability has not been fully revealed.
