Battery Voltage Keeps Going up And Down – Causes & Fixes

3. State of Charge (SOC) and Voltage. The state of charge (SOC) is the remaining battery capacity as a percentage of its total capacity. Voltage and SOC are related, with higher voltage indicating a higher SOC. As a battery discharges, its voltage decreases, signaling a lower SOC. 4. Charging and Discharging Cycles

Lithium-ion batteries explained

A Li-ion battery (a set of Li-ion cells in series) is charged in three stages: Constant Current, Balance (not required once a battery is balanced) and Constant Voltage. During the constant current phase, the charger applies a constant current to the battery at a steadily increasing voltage, until the voltage limit per cell is reached.

19.2: Electric Current

Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
