Is it true that the larger the capacity of the car battery, the better?

Generally, friends who have a car want to replace the battery with a larger capacity when replacing the car battery. In fact, this is not a very correct way. The battery capacity and the generator will not match the battery's life. Let me analyze with you the results of large or small battery capacity! Reasonable selection of the charge capacity of the battery according to the engine type and use conditions is one of the important ways to improve the economy of the battery and prolong its service life. When the engine is started, the battery output current is very large, under normal circumstances it is 150A-200A, and the output current is as high as 250A-300A when starting at low temperature (-10℃). If the charge capacity of the battery does not match the engine, and the charge capacity of the battery is too small, when the starting resistance is large, the battery with a small charge capacity will accelerate the reaction of the active material and the sulfuric acid per unit time and increase the temperature of the battery when the battery with a small charge capacity is violently discharged. High, the electrode plate will bend due to overload, resulting in a large amount of active material falling off, the electrode plate is damaged early, and the battery life is greatly shortened. If the charge capacity of the battery is too large, although the above-mentioned problems will not occur, the active material of the battery cannot be fully utilized, which will reduce the economy of the battery. Therefore, the charge capacity of the battery must match the engine. Generally, the choice of battery charge capacity should be based on the power, voltage of the starter and the load of electrical equipment. The simplest treatment is to replace as many amperes as the car is originally equipped with. Not all car engines are suitable for large-capacity batteries.
