Will the car battery low power warning light come on?

[ElisaFitz]

Car battery low power warning light will not come on. If the engine warning light is on, it should be due to a historical fault code. It is recommended to go to a 4S store or auto repair shop to use a decoder to directly clear this fault code, after which the engine warning light will no longer illuminate. Below are the reasons for battery low power: Reason: The electrolyte (dilute sulfuric acid) in the original SUBARU car battery will gradually evaporate when the battery temperature rises, especially in summer. Unscrew the four sealing plugs on the battery to check, there are anti-splash vent holes designed to release the steam generated inside the battery due to temperature increase. As the electrolyte decreases, the battery's power storage capacity will gradually decline. In late autumn and winter, especially during cold starts after prolonged parking or when driving at low speeds, the battery may not charge sufficiently or may even discharge unidirectionally. At this time, the battery temperature is very low, and the electrode discharge reaction is not active, leading to obvious low power or even complete depletion of the battery's stored energy.
