In vehicles equipped with a battery that requires maintenance, what must be checked periodically to ensure proper functioning?

Question

DentroTest · Accepted Answer

The correct answer is to check the electrolyte level in the cells. Detailed Explanation: Batteries that require maintenance have caps allowing access to the internal cells. Inside, there is a mixture of distilled water and sulfuric acid (electrolyte) that must cover the lead plates (usually by about 10-15 mm). Due to charging and heat, the water evaporates over time.   What to do?: If the level is low, it must be topped up only with distilled water, never with acid or tap water.   Additional Maintenance: Terminals should be kept clean, tight, and protected with grease or petroleum jelly to prevent corrosion. Why other options are incorrect:    Tire condition and washer fluidare crucial general vehicle checks, but they are not components of the battery itself.
