In automotive use, the result of attaching one battery cable to the body or frame which is used as a path for completing a circuit in lieu of a direct wire from a component. Intercell connections - Connections between the straps of two cells, positive of one cell to the negative of the next. The voltage of a battery when it is not delivering or receiving power. It is 2.11 volts for a fully charged battery cell. Plates - Flat, typically rectangular components that contain the active material and a mechanical support structure called a grid, which also has an electrical function, carrying electrons to and from the active material.
Plates are either positive or negative, depending on the active material they hold.
Separators - Porous plastic, electrically insulating sheets which allow transfer of ions between plates, but prevent physical contact between plates and resulting electronic conduction. Terminals - The electrical connection from the battery to the external circuit. Vents - Components that allow gasses to exit the battery while retaining the electrolyte within the case. Can be permanently fixed to the cover or removable, depending on battery design.
