In winter, the capacity of lead-acid batteries generally decreases by 30%, which means that the capacity is only 70% of the capacity at the appropriate temperature. Lead acid batteries are commonly used in electric vehicles, and their storage capacity is closely related to temperature. 25 degrees Celsius is the optimal temperature for using lead-acid batteries. As the temperature decreases, the chemical activity inside lead-acid batteries also decreases, and the resistance naturally increases, ultimately leading to a decrease in battery capacity and weakened storage capacity.

　　1. Diligent charging: In order to extend the service life of lead-acid batteries, the first thing to do is to charge them frequently, and fully charge them. Try not to use them in a state of low power. Every time you charge them, they should be fully charged before use, in order to achieve the best performance of lead-acid batteries.

　　2. Battery warmth: The storage performance and capacity of lead-acid batteries are severely affected by temperature. When the temperature is very low, the performance of the chemical substances inside the battery will be affected, causing the resistance to increase, the capacity to decrease, and the storage capacity to weaken. Therefore, when charging the battery in winter, it is also necessary to pay attention to the battery warmth work, which can be charged in a higher temperature environment. This maximizes the battery capacity and effectively extends the service life of lead-acid batteries, It can also make the battery life longer.

　　3. Pay attention to moisture prevention: In a cold environment, the surface of the battery may experience frost formation. In this state, do not charge it directly. You need to first place it in a warm environment to defrost, then wipe off the surface water droplets, keep it dry, and then charge it.
