Types of batteries

The batteries used in general cars are lead-acid batteries. There are two types of common lead-acid batteries, one is water-added lead-acid batteries, and the other is maintenance-free lead-acid batteries.

Maintenance-free lead-acid battery: Due to its structural advantages, the maintenance-free battery consumes very little electrolyte and basically does not need to be supplemented with distilled water during its service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. The service life is generally twice that of ordinary batteries.

The maintenance-free batteries on the market are divided into two types: the first one is to add electrolyte once at the time of purchase and no maintenance is required after use; the other is the battery itself The electrolyte has been added and sealed before leaving the factory, and the user cannot add refill at all.

Winter is a season of high incidence when vehicles are not easy to start, especially in the cold morning, it is more prone to collapse. Why can't I start the vehicle when I want to go out in the morning? The most common cause is a battery failure.

What is the reason why the battery failure is more likely to occur in winter?

1. The electric energy required for cold start of the engine at low temperature is greater

At low temperature, the oil viscosity is high, and when starting the vehicle The running resistance is greater, so the spark plug requires higher ignition energy. This allows the battery to have higher power support during cold start at low temperatures.

2. The performance degradation of the battery under low temperature is serious

The performance degradation of the battery is mainly reflected in the reduction of the electric capacity and the charging efficiency Decline. At low temperatures, the performance of the battery decreases, and at the same time, there are higher requirements for the battery when starting the vehicle. This becomes the horse running, but not feeding the horse, then it is normal for the horse to strike.

What should we do to avoid battery strikes in winter?

For vehicles equipped with ordinary batteries, you can regularly observe the status of the battery through the observation hole on the battery. A battery in good condition should be green when seen through the observation hole. If you find that the color of the battery observation hole is not green, you need to go to the nearest SAIC Volkswagen authorized dealer for after-sales inspection and maintenance of the battery.

For vehicles equipped with automatic start-stop function, AGM batteries or EFB batteries are generally used in the car. It is recommended that users go to SAIC Volkswagen franchised dealers for after-sales service and use special diagnostic equipment to check the battery status.

If the battery status is found to be degraded, it can be charged through a special charging device; if the battery performance is severely degraded, it will take 12-15 hours of constant current charging, which will affect the customer’s Use a car; if the test shows that the battery is seriously deficient and cannot be replenished by charging, the battery assembly needs to be replaced.

Especially for customers with a small average daily mileage, it is recommended to conduct regular after-sales testing instead of waiting for routine maintenance or starting difficulties. , To avoid the increase in maintenance costs.
