What Are the Consequences of Reversing Car Battery Terminals?

[StBraxton]

Reversing the positive and negative terminals of a car battery can cause many electrical appliances in the vehicle to burn out when powered on, and it can also blow the fuses. The following are precautions for using a car battery: Avoid Deep Discharge: Most batteries on the market today are lead-acid batteries, which consist of positive and negative plates immersed in a box filled with sulfuric acid electrolyte. If the battery undergoes deep discharge, a chemical reaction occurs between the electrolyte and the plates, forming a large amount of lead sulfate. When lead sulfate accumulates to a certain extent, it hardens into irreversible crystals. These crystals have poor conductivity, affecting the battery's charging and capacity, so it is essential to avoid battery depletion. Avoid Excessive Temperatures: Most car owners only know that batteries are sensitive to cold, as low temperatures can reduce battery capacity and make starting difficult. However, excessive heat is fatal to the battery.
