What is the difference between AGM automatic start-stop battery and an ordinary battery?

In order to save fuel, more and more new cars are equipped with automatic start-stop functions. Cars equipped with this function will be accompanied by an independent Agm start-stop battery. This battery only works for the automatic start-stop system alone. So for the same battery, what is the difference between AGM start-stop battery and an ordinary battery? Why is an additional battery installed?

What is an AGM start-stop battery?

AGM start-stop battery, short for lean liquid valve controlled adsorption glass fiber cotton separator lead-acid battery, is a kind of lean liquid battery. AGM start-stop battery is inside the battery USES the adsorption type glass fiber cotton clapboard, can fully sufficient electrolyte adsorption, through the barren solution type tight fittings, to ensure the active substance is fixed in the glass fiber mat, prevent loss of active material, but also maintain internal electrolyte flow, thanks in large part to avoid the "electrolyte stratification" phenomenon in a battery, The AGM start-stop battery has higher capacitance stability in the electrochemical reaction cycle. In this way, no matter AGM batteries are placed vertically or horizontally, they can work normally.

Analysis of the influence of engine start-stop system on fuel loss?

The start-stop technology mainly has an obvious effect on comprehensive urban working conditions, such as waiting for traffic lights frequently. Generally, as long as the engine is stopped for more than 10-15 seconds, the system will start or shut off the engine according to the actual situation, so that the engine can reduce unnecessary idle operation, save fuel and reduce emissions. Since everyone's driving habits are different, the economy is not the same for everyone. The current idle fuel consumption of the car is about 1.2-1.5 liters/hour, and the actual cost of the start-stop system is about 2-3 thousand yuan. If you drive in the city, there is a certain economic effect. Comprehensive tests show that vehicles with automatic start-stop functions can reduce fuel consumption and carbon dioxide emissions by about 4% to 6%.

What is the difference between AGM automatic start-stop battery and an ordinary battery?

So an ordinary battery can replace an Agm start-stop battery? The answer is no. After a short period of installation, the difference may not be found, but because the working intensity of the ordinary battery can not meet the requirements, after a start, the battery will be in an obvious power deficit state. When the system detects that the battery charge is insufficient to restart the vehicle, the start-stop system will not work.

Ordinary battery and Agm start-stop battery perform their duties, and have different characteristics, otherwise the manufacturer will not increase the cost separately for no reason to place a new Agm start-stop battery.
