At its most basic, battery voltage is a measure of the electrical potential difference between the two terminals of a battery—the positive terminal and the negative terminal. It''s this difference that pushes the flow of electrons through a circuit, enabling the battery to power your devices. Think of it like water in a pipe: the higher the pressure (voltage), the more water
Overcharging: When the battery is already full, the charger continues to supply power, causing the battery to become overcharged. This can lead to increased heat, oxidation, and degradation. Power cycling: When the battery is fully charged, the charger may continue to supply power in short bursts, causing the battery to cycle on and off. This
The charger will draw the most power from the power mains whilst it is in heaviest part of the charging cycle. As the battery becomes charged the line load will taper off to the idling mode. Note that there can be wide variation on amount of idle power that various chargers can consume.

The last phase of litium ion charging used a constant voltage output that is the same as the target voltage of the cell. So the battery will only charge until its voltage is the same as the input. A simpel way to detect it if is fully charge is to measure the current into the battery and when it is low enough you consider it fully charged
When the starting voltage (in a single lithium-ion cell) reaches close to 4.2 volts, then the battery is fully charged. If it discharges under a voltage of 3.0 volts, its life deteriorates automatically and also loses its capacity to support the device''s functions. Most devices have a battery that power supply cutoff system in them.
Laptop chargers pretty much universally turn off (or go into low "trickle" mode) when the battery is fully charged. There is a problem, however, that your typical Li-ion laptop battery "doesn''t like" being fully charged -- the overall battery life (not the "life" of a single charge) will be extended if only charged to 60-80%.
A fully charged car battery measures 12.6 volts when the engine is off. This value, known as “resting voltage,” indicates a full charge.
