1. Reasons for the decrease in endurance of lead-acid batteries in winter

Temperature effect: The reaction rate of lead-acid batteries is affected by temperature. As the temperature decreases, the viscosity of the electrolyte in lead-acid batteries increases and the ion diffusion rate slows down,spot welding machine resulting in an increase in the internal resistance of the battery. This reduces the battery's usable capacity and discharge performance, resulting in reduced range.

Electrode grid corrosion: In low temperature environments, the electrode grid of lead-acid batteries is easily corroded.battery machine This corrosion will cause the plates to deform, increase the gap between the plates, and make it easier for the electrolyte to drain. This will not only shorten the life of the battery, but also reduce its discharge performance and endurance.

Reduced charging capacity: As the temperature decreases, the charging capacity of lead-acid batteries decreases.cell manufacture This means that within the same charging time, the battery cannot meet its expected capacity, resulting in shortened battery life.

Electrolyte freezing: At extremely low temperatures, the electrolyte in lead-acid batteries can freeze. This will lead to changes in the internal structure of the battery, affecting the normal operation of the battery and further reducing its endurance.

2. Methods to improve the durability of lead-acid batteries in winter

Preheat charging: Before charging, preheat the lead-acid battery. Thermos bottles, heat guns, and other tools can be used to heat batteries to relatively high temperatures. This improves the battery's charge acceptance, allowing it to hold more power during the winter.

Replace the cold-resistant battery: Choose a lead-acid battery with better cold-resistant performance. The electrolyte still cannot maintain a good fluidity at low temperatures, which can reduce the possibility of the electrolyte freezing. In addition, the plate grid of the cold-resistant battery has also undergone some special data processing, which can effectively resist corrosion in low-temperature environments and improve the life and discharge performance of the battery.

Proper use of chargers: When using lead-acid batteries in winter, you should choose a charger suitable for winter use. The charger can automatically adjust charging parameters based on temperature to avoid overcharging or overcharging. At the same time, ensure that the charging environment temperature of the charger is higher than 0 °C to avoid freezing of the electrolyte.

Regular maintenance: Regular inspection and maintenance of lead-acid batteries, including checking the concentration and level of electrolyte, cleaning dust and dirt on the battery surface, etc. This ensures the proper functioning of the battery and improves its discharge performance and battery life.

In short, there are many ways to improve the life of your battery during the winter. By preheating, replacing cold-resistant batteries, rationally using chargers, and rationally maintaining and using vehicles, the winter service life of lead-acid batteries can be effectively increased.
