Audi Q5 cannot disconnect the battery. Cutting the battery cable by yourself will lock the car's computer, and decoding is required to use it again. How the battery works: The car battery, also called a storage battery, is a type of battery. Its working principle is to convert chemical energy into electrical energy. Usually, the battery people refer to is a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. Precautions for using car batteries: Frequent short-distance driving and stop-and-go driving can cause the car battery to be in a state of insufficient charging for a long time, shortening its lifespan. Driving at a steady speed on the highway for 20 to 30 minutes can give the car battery enough time to charge. If you want to save gasoline, you can use an external charger to supplement the battery's charge.
