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. The fastest ONE+ charger ever. Charges at a rate of 5.0Amp/h meaning you can charge a 5.0Ah battery in 1 hour 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. Lithium+ battery technology gives more power, longer runtimes and better durability than previous lithium 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.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. 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. 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. 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. 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.

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 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. 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.There are ways of converting (or inverting) electricity, you guessed it, using converters (AC to DC) or inverters (DC to AC). That's another article in itself. You can learn what is an inverter and
