  What are the characteristics of AGM car batteries?

  AGM car batteries have the characteristics of extremely low water loss, strong cold starting performance, high safety, etc., and also have excellent charging reception capabilities. In addition, before the battery fails, it will have difficulty starting, the battery fault light will come on, and when idling, If there are signs of dimming of the lights, then the following will introduce the relevant content in detail.

  1. Characteristics of AGM car batteries

  1. Internal oxygen recycling, with extremely low water loss;

  2. Glass fiber absorbs electrolyte: no acid leakage;

  3. By casting the grid, the phenomenon of plate growth will not occur;

  4. The battery life is longer, 3 times that of ordinary maintenance-free batteries;

  6. Strong cold starting performance, more than 30% better than ordinary batteries;

  7. High safety, even if the shell ruptures in a collision, acid will not flow out and corrode the vehicle;

  8. Excellent charging reception ability, quickly replenishing power consumption and timely absorbing the energy generated by braking.

  2. Precursors of car battery failure

  1. Difficulty starting the car

  In the absence of other factors, if your car suddenly has difficulty starting, it may be a sign that the battery is about to fail. If it is winter, there is another possibility, which is the so-called cold start difficulty.

  2. When the car is idling, the lights dim

  For example, when waiting at a red light or temporarily parking, your headlights suddenly dim. This is because the charging power of the engine decreases when idling. If the battery is almost unusable at this time, and it also needs to supply power to other equipment in the car, the car headlights will consume a large amount of power, resulting in insufficient power supply, resulting in dimming of the lights.

  3. The battery fault light is on

  When the battery fault light comes on, it reminds you that you should go to a repair shop for maintenance and testing of the battery.

  4. Abnormal noise occurs during startup

  As the battery's discharge capacity weakens, the starter will run poorly and make a squeaking sound. This situation is especially obvious at low temperatures. Because the weather is cold, the activity of the battery will also decrease, but it will be improved or disappear after the weather warms up. , so many car owners don’t take it seriously.

  5. Battery observation hole

  There is an observation hole on the maintenance-free battery. The light in the observation hole shows whether the battery is working well. If it is green, it means good, and if it is black, it means the battery needs to be replaced. However, some car owners also report that this light is unreliable and they cannot start even if it is green. Car, observation hole as a simple reference.

  6. The battery surface bulges and leaks.

  The main thing here is to check whether the battery is bulging or leaking. If such a situation is found, please replace it in time. If not, there will be safety hazards. Remember to replace it.
