Our world revolves around electricity, a fact that becomes truer every day. A component of electricity availability that's becoming increasingly important is the battery. Batteries are in pretty much everything, from phones, to computers, to cars and even power supplies for homes.

Using a 5.0ah battery (included) with the Ryobi RPD18 Combi Drill, you can drive up to 1550 4 x 32mm wood screws on a single charge. Using the included charger, the Ryobi 18V ONE+™ 5.0ah Lithium+ battery will charge from flat in just 60 minutes. Features: Even though the Amp=-hours doesn't automatically mean the battery is more powerful by the numbers, sometimes it can equate to more power. In a higher Ah battery, the number and density of cells supplying the current and the heavier gauge of the conductors and components involved allow more current to move with less resistance.So, for example, if you have a fully-charged 5-Ah battery, it can provide five amps of current for one hour. If your device requires one amp of current to run at full speed, then the full charge would last about five hours, under ideal conditions, of course. Using a 5.0Ah battery with the Ryobi R18PD3, you can drive up to 1550 4 x 32mm wood screws on a single charge. Charger sold separately. Features: Ohms are like the width of the canyon. The narrower you make the canyon (or wire), the harder the voltage has to work to push the same amount of amps through. The result is the generation of heat. Electricity is broken down into three standard units, resistance (R), voltage (V), and current (I). Voltage is measured in volts, resistance in ohms, and current in amperage.

Lithium+ battery technology gives more power, longer runtimes and better durability than previous lithium batteries We've already covered amps. If we continue our river-in-the-canyon analogy, volts are like the pressure of the water through the canyon, the force pushing the current through. Alternating current (AC), on the other hand, alternates directions a set number of times per second—60 times per second in the United States.Batteries are always DC. That's why there is a positive and a negative terminal. It will always flow consistently from one terminal towards the other through the appliance using power. Electrical devices are made to function on either AC or DC, never both, without modification. Amp-hours, or Ah for short, are a unit of measure for a battery's energy capacity. This rating tells us how much current a battery can provide at a specific rate for a certain period. For example a 5.0Ah Ryobi battery will last much longer than a 1.0Ah battery, but not 5 times as long as there is always a slight decline. Where you can afford to, you should always buy the biggest Ah rating that you can afford as this will give you the longest battery life. Whereas voltage measures the potential energy of a battery, it is the Ah rating (usually 1.0Ah to 6.0AH) that measures the capacity of the battery. As a general rule, the larger this number is, the longer your battery will last for on each charge and you should always use a lithium battery. Higher voltages such as 18V and 20V are required to power heavier use power tools like hedge clippers, impact wrenches, cordless drills etc.

Many factors affect how long Ah will last in a battery. These include the rate at which the battery charges and discharges, ambient temperature and environment surrounding it, and the overall condition and age. Regardless of these variables, Amp-hours remain an important indicator of how long your devices can reliably run on one charge. Basically, amperage can be described as the volume of electrical current. It is an essential indicator of how much energy can be moved by an electric device or system. What are amp hours and what does Ah mean in a battery? Smaller voltages can operate smaller power tools like cordless screwdrivers, rotary tools and light use drill/drivers. In all cases a lithium battery is the best choice. Ryobi's IntelliCell individual cell monitoring helps to maximise tool running time and performance. The battery is also compatible with old as well as new Ryobi One+ tools. Enjoy access to more than 40 garden and power tools. With a higher battery capacity and voltage, the Ryobi One+ RB18L50 18V 5Ah is ideal for users who demand a long running time. No Need to Constantly Recharge

The higher Ah also means you'll be able to power more things for longer with less strain on the battery components. An easier workload will impact the longevity of the battery itself.

Those batteries with larger voltage sizes are heavier than smaller voltage batteries and that is always a consideration for manufacturers depending on the actual use of the tool.
