In addition to providing the starting power required, the automotive battery also supplies power to accessories such as lights, fans and radio when the engine is not running. Between low engine speeds and when accessory load is greater at high running speeds, a battery makes up the difference by stabilising the alternator output.
This stabilising effect also protects a vehicle’s electrical system by smoothing out sudden high voltages which can damage electrical components.
