The battery life of lead-acid batteries decreases in winter, don’t worry, you will know after reading this article

Reasons why the service life of lead-acid batteries decreases in winter

Temperature effect: The chemical reaction rate of lead-acid batteries is affected by temperature. As the temperature decreases,ESS battery machine the viscosity of the electrolyte of the lead-acid battery increases and the ion diffusion rate slows down, 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.

Gate corrosion: In low temperature environments, lead-acid battery grids are susceptible to corrosion.Solid-state batteries This corrosion can cause the plates to deform, increasing the gaps between them and making electrolyte loss more susceptible. This not only reduces battery life, but also reduces its discharge performance and battery life.

Decreased charge acceptance: As the temperature decreases, the charge acceptance of lead-acid batteries also decreases.sodium ion battery This means that within the same charging time, the battery cannot be fully charged to the expected capacity, resulting in reduced battery life.

Electrolyte Freezing: At extremely low temperatures, the electrolyte in lead-acid batteries can freeze. This will directly lead to changes in the internal control structure of the battery, affect the normal management of the battery, and further reduce its battery life.

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 cold-resistant lead-acid battery, whose electrolyte can still maintain good fluidity at low temperatures, thereby reducing the possibility of the electrolyte freezing. In addition, the grids of cold-resistant batteries are also specially treated to resist low-temperature corrosion and improve battery life and discharge performance.

Reasonable use of chargers: When using lead-acid batteries in winter, choose a charger suitable for winter use. This charger can automatically adjust charging parameters based on temperature to avoid overcharging or undercharging. At the same time, it is necessary to ensure that the charging environment temperature of the charger is above 0°C to avoid freezing of the electrolyte.

Regular maintenance: Regular analysis, inspection and maintenance of lead-acid battery technology, including safety inspection of electrolyte concentration and liquid level, cleaning of dust and dirt on the surface of battery materials, etc. In this way, we can improve its discharge performance and endurance problem by ensuring the normal management of the battery.

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.
