Starting and stopping batteries can be distinguished by appearance. The starting and stopping battery has a special label on the appearance, while the ordinary battery has no special symbol.

Start stop battery, also known as maintenance free battery, is currently generally AGM and EFB. The special symbols of the two kinds of batteries are different. The details are as follows:
Valve controlled, VRLA and AGM batteries are all valve controlled AGM batteries.
Marked with ST、N55、Q85、S95、EFB、start/stop、idle stop system for vehicles and other words, are EFB start stop battery.
In other words, in the appearance of the battery, if you see one of them, you can judge that the battery is Start-stop battery.
AGM originated from the United States of exed, European cars or German cars, generally use AGM. EFB originated in Europe, Germany, Moll, Japanese cars generally use EFB.
In addition to the differences in appearance, there are also the following differences between starting and stopping batteries and ordinary batteries:
1. The weight of starting and stopping battery is heavier than that of ordinary battery.
2. Shake the battery, there is no sound of liquid.
Is it possible to replace the start-stop battery with a conventional battery when the automatic start stop system is switched off?
1. Program mismatch. The vehicles equipped with start stop system, especially the middle and high-end models of European series, are generally equipped with battery management system (BMS). At the same time, the control network and power consumption system of these vehicles are also more complex. If the EFB or AGM battery is replaced by ordinary battery, the power management system generally does not have the corresponding program with ordinary lead-acid battery, so it is impossible to complete the initialization of battery, and it is also difficult to use That is to say, BMS does not recognize ordinary lead-acid batteries, which will lead to many systems on the car not working properly.
2. Different charging modes. Different kinds of batteries have different charging procedures, especially the charging mode of ordinary wet lead-acid battery is different from that of AGM battery. In some models, if AGM batteries were originally required, they would be replaced by ordinary wet lead-acid batteries. Even if the discharge current can meet the power demand, due to different charging modes, not only the batteries will be damaged prematurely, but also the whole system may not work normally.
3. As the high temperature resistance of AGM battery is not as good as that of ordinary lead-acid battery, it is usually installed in the trunk or car. The common lead-acid battery will inevitably have acid mist discharge in the process of charging and discharging, which is bound to affect the health of drivers and passengers in the car.
To sum up: start stop battery and ordinary battery are different in appearance, start stop battery is heavier than ordinary battery, and there is no liquid sound when shaking. When the automatic start stop system is turned off, ordinary batteries can not be used to replace the start stop batteries, because the program does not match and the charging mode is different. The high temperature resistance of AGM batteries is not as good as ordinary lead-acid batteries, and most of them are installed in the trunk or car. The common lead-acid battery will inevitably have acid mist discharge in the process of charging and discharging, which is bound to affect the health of drivers and passengers in the car.
