This innovative battery is suitable for 18V Ryobi One+ RB18L50 18V 5Ah and NICAD ONE+ Ryobi tools. Why not build your own collection of ONE+ tools by buying the batteries and chargers you need? This can include their cordless screwdrivers or some sanders and grinders. Maximum Running Time 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. 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: 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:

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. The fastest ONE+ charger ever. Charges at a rate of 5.0Amp/h meaning you can charge a 5.0Ah battery in 1 hourIf you hook something up to the wrong form of electrical delivery, it won't end well for your devices. IntelliCell™ technology monitors and balances individual cells to maximise run-times, storage life and safety 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. There's no need to constantly recharge the battery. You'll be able to drill more holes, drive in more screws and cut more using tools in the One+ range without any interruptions. The four-stage fuel gauge shows the remaining power so you always know how much charge you've got left. Save Money

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. Lithium+ battery technology gives more power, longer runtimes and better durability than previous lithium batteries 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.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. As you can see Ryobi have many different batteries available. Why do manufacturers like Ryobi make different voltage of batteries?

Heat causes a loss of electricity, called voltage drop, which also lowers the force the voltage can provide and decreases the amperage that can get through. We minimize resistance through material choices, like copper or aluminum, and increasing the size of the conductors and components used. The less heat that is generated, the better for everything involved. Higher voltages such as 18V and 20V are required to power heavier use power tools like hedge clippers, impact wrenches, cordless drills etc.Amperage, also known as electric current, measures the rate at which electrons flow through a conductor or object. This rapid flow can be thought of as similar to water flow through a channel or canyon. The higher the amperage, the greater volume of electrons moving. It's better to size up than to run the risk of undersizing. You don't want to run out of power on accident because you chose a 200Ah battery when you needed a 250. Does a higher Ah battery mean more power? 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. Most people know that AC and DC electricity are two different types of current, but few know how they differ. 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.
