Why can't the battery work when it's cold?

When the temperature drops in winter, the endurance and power of both lead-acid batteries and lithium batteries will be affected to some extent, and the endurance will decrease, and the power will obviously feel insufficient.

As far as lead-acid batteries are concerned, when the battery capacity is based on 25℃, the battery capacity will decrease by 1% every time the ambient temperature drops. When the temperature is lower than 5 degrees, the battery life decreases more obviously. Lithium batteries are also afraid of low temperature. When the temperature becomes lower, the decomposition of active substances in the battery will be insufficient, resulting in insufficient battery life.

However, if we pay a little attention every day, the battery life of electric vehicles in winter will be improved to some extent.

1. In winter, the electric car can only charge 70% of the points, and the lights will jump. At this time, they can float 1-2 hours, so it is suggested to ensure that the charging time in winter is 8- 10 hours, which will increase the storage capacity of electric vehicle batteries.

2. cycling in cold weather, pay more attention to battery capacity. Charge in time, don't wait until the battery is completely exhausted.

3. Recharge after riding for one hour. Because the battery temperature will continue to rise during the riding of the electric vehicle, the battery of the electric vehicle just finished riding will heat up, and charging immediately at this time will lead to the loss of materials inside the battery. You can wait about an hour before charging to give the battery a cooling buffer time.

Considering the quality, after-sales service and price of battery products, we recommend a very good brand of lead-acid battery: Changxin battery.

Changxin battery, as an old lead-acid battery production group, has been praised by the market for its excellent reputation and quality for many years. As a high-end product in lead-acid batteries, Changxin Graphene Series adopts a more scientific in-line structure and an upgraded formula with higher energy density and high technology content, which brings longer life, longer battery life and more stable performance.
