The 'Ah' or 'Ahr' rating is Amp-hours. To a 4.0 Ah battery will provide 4 Amp-Hours of power. That means 4 Amps for 1 hour, or 1 Amp for 4 hours… whatever it is, you can determine the expected runtime by dividing the potential stored (4 Ah) by the power demanded (in Amps) to get the number of hours it should run.

The RYOBI 40V System puts the power in your hands to tackle yardwork and more demanding jobs without having to plug-in or fill-up. With 50 innovative tools and counting, each product is engineered to deliver GAS-LIKE POWER™ for superior performance and fade-free runtime - from first cut to last.

The higher the voltage, typically, the more cells that are in the battery pack. So when comparing a 40V pack to a 20V pack, in most cases the 40V pack will have more cells which means more power capacity available.

A Ryobi 40V, 4-amp battery can take up to one hour to recharge for each 25-percent increment, requiring as long a 4-hours to completely recharge a discharged battery.

The RYOBI 40-Volt Power Source provides convenient, on-the-go power both on and off the jobsite. With 300-Watt of continuous output, this inverter is perfect for powering laptops, tablets, cell phones and other small electronics.

A higher amp hour battery does really have more capacity. Additionally, they typically last longer than smaller Ah batteries for the same amount of power consumption. A 4Ah battery has twice the capacity of a 2Ah battery, which makes it more durable under the same conditions, that is, it can provide longer use time.
