When riders face this ...
This page has a good answer: "it depends". The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.
Yes, you can use a multimeter to measure the voltage of the car battery. A fully charged battery should read around 12.6 to 12.8 volts. If the voltage is significantly lower, it may indicate that the battery is not fully charged and might require a recharge or replacement. 3. Are there any visual signs to indicate a fully charged car battery?
The battery is fully charged when the current drops to a set low level. The float voltage is reduced. Float charge compensates for self-discharge that all batteries exhibit. The switch from Stage 1 to 2 occurs seamlessly and happens when the battery reaches the set voltage limit. The current begins to drop as the battery starts to saturate; full charge is reached …

The only accurate way to tell if a VRLA DRY CELL AGM or GEL battery is fully charged is by using a good voltmeter to determine the open circuit voltage (OCV) without any load applied to the battery. Accessible flooded-type batteries can also use a hydrometer. Table 5 - …
Lithium batteries should be kept at around 40-50% State of Charge (SoC) to be ready for immediate use – this is approximately 3.8 Volts per cell – while tests have suggested that if this battery type is kept fully charged the recoverable capacity is reduced over time. The voltage of each cell should not fall below 2 volts as at this point the anode starts dissolving …
Once the battery is fully charged it will not accept any more energy (current) from the charger, since all the energy levels that were depleted when empty are now at their highest level. For example in a Lithium ion battery when all the ions have arrived at the proper electrode the resistance to more current becomes very large, but not infinite since there will be some …

This accelerates the higher the air humidity is. As a result, the battery starts to discharge itself, which increases the risk of discharging. As already mentioned, temperature also plays a decisive role. A temperature between 10-40 degrees Celsius is recommended for batteries, but a cool room temperature of 15-20 degrees Celsius is optimal.
This happens more readily when the battery is kept at high voltage (fully charged) and low temperature. Lithium plating reduces cycling stability and poses safety risks like internal short circuits.
