A battery pack consists of two or more cells and determines the power or voltage rating of a tool. A screwdriver with a two-cell pack develops 2.4 Volts, while a drill-driver with eight cells develops 9.6 Volts.
Two or more electrochemical cells electrically interconnected in an appropriate series/parallel arrangement to provide the required operating voltage and current levels. Under common usage, the term "battery" is often also applied to a single cell.
a case which contains several batteries connected in series or in a row, available to charge more energy (power) in use
a collection of batteries joined together to combine the voltage of the batteries needed to power an electrical device
a rechargeable, removable
a set of cells and their protection/authentication/security circuitry (Figure B)
An assembly of electrochemical cells electrically interconnected in an appropriate series/parallel arrangement to provide the required operating voltage and current level. A battery pack most often includes an additional jacket and wires/connectors. In this documentation, the term "battery" is used instead of battery pack unless exclusion of a single cell without the cable and connector is intended.
A rechargeable battery used in portable computer devices, such as notebook computers. The most common substances used in computer battery packs are nickel cadmium (Nicad), nickel metal hydride (NiMH), and Lithium Ion. A new type of battery, called a smart battery, provides the computer with information about its power status so that the computer can conserve power intelligently. With a normal battery, the computer makes estimates about the battery's condition that are not always correct.
A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage, capacity, or power density. The term battery pack is often used in reference to RC hobby toys and battery electric vehicles.
