3. Battery indicator
Battery indicator is a part of instrument panel indicator which is a warning light that indicates a problem with the vehicle's electrical system.
The battery indicator is a device that provides information about the battery. This is usually a visual representation of the battery status. It is especially important in the case of an electric car battery.
If a battery alert light (a battery-like light bulb) on the dashboard comes on while driving, this means that the charging system is not working, but the error may lie in something other than the battery.
