Many car owners feel that the automatic start and stop of their car is too chicken ribs, daily life can not be used at all, more importantly, the automatic start and stop type should be equipped with a more expensive special battery - AGM battery. So many car owners are thinking, if the car battery with automatic start and stop is broken, can it be replaced with an ordinary battery?
My answer is clear, no. Even if you brush off the automatic start-stop function, you can't change the ordinary battery, because although you can save a little money by changing the ordinary battery, it is not worth the loss in the end. What's different about AGM batteries? AGM battery is a kind of valve-controlled sealed lead battery using glass fiber separator (AGM), which is much more expensive than the general battery, but has the following three advantages: 1, longer life. The life expectancy is about 3 times higher than that of ordinary lead-acid batteries. 2, the capacitance stability is stronger. 3, low temperature reliability is better. At low temperatures, its battery capacity, charge and discharge function is more reliable. 4, can cope with frequent high current start, which is also the most important reason for vehicles with automatic start and stop to use this battery. So why can't models with automatic start-stop use ordinary batteries?
Starter is not the same first is not with automatic start-stop car and with automatic start-stop car, their starter is not the same, although the working voltage is 12V, but there is an automatic start-stop car, its starter working current is larger, must use AGM battery to support large current discharge, the current of ordinary batteries is difficult to support, easy to start difficulties, speed is not enough problems, in addition, the price of the starter is more expensive than the battery, if the damage to the starter will be more than worth the loss. Easy to cause abnormal power management system For models equipped with automatic start and stop, the power management system will be matched according to the characteristics of the AGM battery, including battery capacity, charge and discharge current, etc. If you replace the ordinary lead-acid battery, it may cause the power management system to be unable to match the lead-acid battery, resulting in a fault prompt that the battery cannot initialize, and even cannot ignite, and the system cannot work properly.
Vehicles with automatic start-stop function that affect the health of occupants generally have AGM batteries placed under the trunk cover because the AGM batteries cannot withstand higher temperatures. However, the acid of the AGM battery is 100% sealed, no gas is discharged when working, even if it is placed in the trunk, it will not affect the health of the occupants, but the ordinary lead-acid battery is not the same, and the acid mist in the process of charging and discharging will affect the health of the occupants, and there is a danger of poisoning when it is serious. Therefore, although the automatic start-stop function is a chicken rib, it is also a sticky kraft candy, as long as you buy a car with the automatic start-stop function, it means that you have to pay a higher cost. Frankly speaking, the automatic start-stop function of some Japanese cars is still relatively easy to use, and urban driving can save a lot of fuel consumption. But if you really don't like the automatic start-stop function of the car, it is recommended not to be cheap when buying a car, otherwise you want to castrate it when you use it and replace it with an ordinary battery, it will be too late.
