It's cold and the battery is dead.

In cold weather, the loss of battery power is the most common cause of fire fighting difficulty. Affected by temperature, the lower the temperature, the lower the battery capacity. Generally speaking, the life of a battery is about 3 years. If the engine is difficult to start, the headlights are obviously dimmed or the horn is not ringing, it is necessary to check whether the battery is dead.

Using a battery with good performance to keep the generator in good working condition can provide guarantee for the battery to be fully charged; Pay attention to cleaning the terminals of the storage battery, apply special grease protection when necessary to ensure good contact, and check whether the liquid level and density of the ordinary storage battery are normal; If the vehicle is parked in the open air or in the garage without thermal insulation facilities for a long time, the battery can be taken out and stored in a warmer room to prevent the battery from freezing. In addition, pay attention to the working conditions of spark plugs and ignition coils to ensure their normal work.

Finally, I want to tell you some ways to maintain the battery in winter:

First: Because the electrodes of the battery are easily corroded in cold weather, riders should always pay attention to the two electrodes of the battery. If oxide is found, it should be washed off with boiling water, then dried and coated with vaseline to prevent the electrode from being oxidized again.

Secondly, try to use low-temperature engine oil with good fluidity in cold weather to avoid high viscosity of engine oil and increase the resistance of starter, thus affecting the battery.

The last one is: never connect a high-power inverter to charge the laptop and other equipment in the car when the car is cold, so as not to cause insufficient battery power and affect battery life. If external equipment must be charged, it is recommended to start the engine.
