$begingroup$ Re: "exceeded for minutes to hours" - I used to connect a 60W solar panel to my car battery every few months and let it charge to equalize it.I don''t recall the peak voltage, but it went over 15.5 for hours. The liquid in the battery made bubbling sounds and "boiled" freely (the hood was open and no danger of a spark).

Common float charging voltages that can be left indefinitely on are 13.5V - 13.8V. Fast charge occurs at voltages of about 14.5V, but then you need the ability to stop the fast charge and switch to float charge once the low current indicates the charging is done. A lead-acid battery with resting voltage below 12.6V will not have a full charge.

Any device will only draw as much current as it needs, so long as its power source can supply it. However, the laptop adapter's voltage is a full volt above the specified 18 V; this will cause more current to flow into your device, since the voltage has been increased.
Just FYI, the symbol in 19V⎓3.42A (two horizontal lines, top line solid, bottom line broken) is Unicode U+2393 ⎓ "direct current symbol form two". It means 19 volts DC. If the supply was labeled 19V~3.42A that would mean 19Vrms AC instead of 19V DC. The weird symbol indicates its a DC output.
