All tool batteries are powered by LiIon cells that range from an absolute 2.8V minimum to 4.2V maximum. That gives 3.6 volts "average". 5 cells make the most basic battery. 5 x 3.6 = 18V. That's how Ryobi choses to advertise their batteries. The average voltage between fully charged and fully discharged == Honest.
Other companies chose to use the maximum voltage only when almost right off the charger and not used which would be 4.0 to 4.2V. 5x4 = 20.
You get no additional voltage, no additional power (wattage) out of same AmpHour battery between one advertised at 18V vs 20V. 18V 4 AH battery from Ryobi is the exact same amount of power as a 20V 4AH from another company due to the stretching of nominal voltage rating.
A Ryobi battery fresh off the charger is usually at least 20.5V without load. That's going to be the same for any manufacturer.
