A red battery-shaped dashboard icon warning that the vehicle's charging system, not necessarily the battery itself, has a fault.
Also known as: Charging system warning light, Alternator light, Generator light
Illuminates when the charging system (commonly the alternator, drive belt, or wiring) is failing to charge the battery — a charging-circuit fault signal, frequently misread by drivers as simply 'flat battery'.
Indicates a fault in the vehicle's charging system — most often the alternator, drive belt, or wiring — meaning the battery is not being recharged while driving, rather than necessarily being dead itself. Briefly illuminates at start-up as a bulb check.
Contexts: Vehicle dashboard
Commonly misread by drivers as meaning the battery itself is flat, when it more precisely signals a charging-circuit fault — the battery may still hold charge at the moment the light appears.
A documented common misunderstanding, not an error in the symbol's own design.

A red rectangular battery outline marked with a plus sign on one side and a minus sign on the other.
