Does a 12V car-mounted pressure washer damage the battery?

[DelJoanna]

12V car-mounted pressure washers do not damage the battery. The car-mounted pressure washer comes with its own water tank and uses the power from the car's cigarette lighter to drive the pressure pump. Through the water hose, switch handle, and spray gun, it emits a high-pressure water jet to rinse off mud and debris from the car's undercarriage. It can also be fitted with a brush for scrubbing. The car battery, commonly referred to as a lead-acid battery, is a rechargeable battery that can be reused after discharging. The positive electrode of the battery is lead dioxide, and the negative electrode is lead, with a dilute sulfuric acid solution serving as the electrolyte. During discharge, the battery's positive and negative electrodes react with sulfuric acid to form lead sulfate. When the sulfuric acid solution concentration drops to a certain level, recharging can restore the electrodes and solution to their original state, allowing the battery to be reused after charging.
