What is the difference between start stop batteries and ordinary batteries?

Compared with the ordinary battery, the automatic start stop battery has much better "instantaneous large current release" ability.

For example, the peak capacity of the ordinary battery instant current release is 280A, so the automatic start stop battery of the same specification can often reach 400A or even higher. Because it needs to start the engine repeatedly anytime and anywhere, so the requirements for this capability are much better than ordinary batteries.

Can automatic start stop battery be forced to use ordinary batteries? Why?

Now, the question is : Can automatic start stop battery be used as a ordinary batteries? Why? The answer is yes! The performance of automatic start stop battery is much better than that of traditional battery. But no one would ever use it! Because the automatic start stop battery is more expensive than the ordinary battery! We are not going to kill a chicken with a knife. So the question is only theoretical.

Second question: Can use automatic start stop battery Vehicles use ordinary batteries? In fact, this problem is quite many owners will encounter. As we know, the peak current release capacity of the ordinary battery is far less than that of the dedicated automatic start stop battery, so the automatic start-stop function is useless when the ordinary battery is installed in the vehicle with the start-stop function.

For most low-end automatic start-stop models, in order to save money and use ordinary battery, the car is nothing but completely lost the automatic start-stop function, which does not affect the normal use of the car (manually turn off the automatic start-stop function!) However, the automatic start-stop function of some cars cannot be turned off, such as many models owned by General Motors, so as long as we remember one trick when driving: push the car into neutral before it comes to a stop, and the engine will not turn off. (But in order to save money on starting the automatic start stop battery , it is uncomfortable to do this every day!) .

There are some high-end models, high-end German models, circuit often with battery parameter detection function, once detected battery performance does not reach the specified performance, the protection system automatically triggered, many functions of the vehicle can not be opened, so they are unable to use ordinary battery.

The automatic start stop battery is divided into AGM and EFB, which is better? Which is more expensive?

Next, I try to answer this question: why do the automatic start stop battery have AGM and EFB? Actually, it starts with the traditional battery. We know that the battery plate is lead plate, and the electrolyte is sulfuric acid solution. EFBs are "PLUS versions" of traditional batteries: thicker plates, higher electrolyte concentrations, and so on. So EFBs are also called enhanced wet lead-acid batteries.

AGM, on the other hand, is a very different process: a thick fiberglass mat is placed between the lead sheets and then an acidic electrolyte is poured into the mat. Because the mat is absorbent, there is almost no liquid electrolyte inside the battery, and the electrolyte does not flow inside the battery. So the stability is excellent. Therefore, AGM is also called "lean liquid battery".

At present, Japanese stop-start models prefer EFB batteries, while German models prefer AGM. The reason is very simple: if the price of ordinary battery is 400 yuan, then the EFB with the same capacity will be about 800 yuan, while Agm Battery because of its complex technology, the retail price may be close to 1600 yuan. Of course, now Mercedes-Benz's high-end models have begun to use Lithium Iron Phosphate Batteries instead of lead-acid batteries,Its performance naturally more powerful, the price is... Let's not think about it.

Automatic start stop battery are expensive, especially AGM batteries. If your AGM is broken, then we can try to replace a half cheaper EFB Battery! If you want to save money, it says here, turn off the car's start-stop function and you can go straight to the regular battery! It is half the price of EFB battery! That is, if you make sure your car doesn't have some wacky battery testing program.
