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%.

No, inverters do not overcharge batteries. Overcharging is a function of the charger, not the inverter. The charger controls the voltage and current going into the battery to charge it. What Happens When Battery is …
When fully charged the voltage at one end of the wire is the same as the other wrt to the -ve so there is current flow. and Therefore, the net electric field inside the wire is zero and the electrons in the wire experience no external force and hence no current will flow.
If you charge an LFP battery to 3,45V per cell (13,8V for a 12V battery) and stay there until current drops, you have charged the battery to 99% and ensure a long life. ... if not: fully charged, if still taking current: not fully charged yet. You are correct, lithium shouldn''t be trickle charged, so you lower to the desired ''charged'' voltage ...
The voltage of a car battery is a measurement of the electrical potential difference between the positive and negative terminals of the battery. A fully charged car battery typically measures around 12.6 volts, with a normal voltage range of 12.4 to 12.7 volts.. It is important to note that the voltage of a car battery can vary depending on several factors.
It''s also worth noting that a 99% charged battery will read 13.4V, and a 93% charged battery will read 13.3V. A 13.6V reading at rest would indicate a newer, fully charged lithium iron phosphate battery, while older units might read 13.5V. As soon as they have any draw at all, this figure falls away quickly. A 99% charged battery will read 13 ...
It looks like that some of the battery charging points are not able to charge the phone (if charge is low), though the phone says charging on display. The same phone gets charged on other battery points. For me, the phones charge only on 2 …
To add to what BustedKnuckles said, if your battery is fully charged, and there isn''t much electrical demand, the voltage regulator, which in all modern cars is a function of the PCM, or car''s "computer", decreases the voltage applied to the alternator''s field windings.
