4LR44 battery.How to extend the life of electric vehicle batteries

　　Against the background that lithium batteries are widely used in new energy pure electric vehicles, some people predict that lithium batteries will replace lead-acid batteries. In fact, it is too early to make such a conclusion. Lead-acid batteries have not been invented since Prandtl in 1859. It has a history of more than 150 years since its invention. It has been continuously reformed and innovated during the development process. It is now more environmentally friendly and safe, with stable performance, mature technology, low price, complete use, and wide range of uses. They have always been favored for their many advantages, but many consumers have also complained about the shortcomings of lead-acid batteries. The main problems are as follows: 1. The quality of the charger is not good, causing the battery to be overcharged. We often see spontaneous combustion of electric vehicles charging in carports, even in winter. In order to reduce costs, some vehicle companies or dealers purchase batteries and chargers separately. When purchasing batteries, dealers will try to choose high-quality, reputable brand batteries, such as Xupai batteries. The quality of Xupai batteries is very good, and the service is also good. Sales, customer service, technical support, maintenance and other aspects are very well established, which can provide consumers with better after-sales service. But the cheaper the charger, the better. If the quality of the charger is not up to standard, the automatic power-off function of the charger will fail due to overload, causing the lead-acid battery to be overcharged. During the charging process of lead-acid batteries, the battery releases heat and the charger also releases heat. Once continuous high temperature occurs and charging continues, spontaneous combustion will occur. In fact, in addition to ensuring the quality of the battery, the quality of the charger is also particularly important. 2. Charge the battery only when it is exhausted or choose fast charging. In order to save time and convenience, many consumers will recharge when the battery is exhausted, or the battery shows that there is still a lot of capacity, so they drive out and drive until the electric vehicle runs out of power, then find an automatic coin-operated place to quickly Charge. As everyone knows, the battery has an under-voltage protection function. If it is still discharging at a high current without battery capacity, the battery life will be significantly shortened. At the same time, fast charging is also a behavior that seriously affects battery capacity. 3. Leaving the battery for a long time without charging can easily cause sulfation. If the electric vehicle is left unused for a long time, we should fully charge it before leaving it. The battery itself has self-discharge phenomenon, so the battery power should be checked regularly and recharged to avoid leaving the battery in a depleted state. If it is in a depleted state for a long time, it will The battery is sulfated and the battery capacity is greatly reduced until the battery fails. 4. Overloading causes great damage to batteries and other components. During the overloading process, a large current is required to discharge, which will cause great impact and harm to the motor, controller, and battery. Some consumers buy electric vehicles in order to carry a lot of heavy goods. It is conceivable that electric vehicles do not use them. You won't be able to run far in a month or two. 5. The car should not be placed in direct sunlight or exposed to rain. Lead-acid batteries are afraid of heat, scalding, and rain. Once exposed to high temperatures for a long time, the battery will have problems. Similarly, the car is afraid of being exposed to rain. If the waterproof function of each power interface of the car is poor, leakage will occur. If it is a large-capacity battery, it will bring the risk of electric shock. 6. Bad riding habits. Some consumers like to push the handlebars as fast as possible when riding, which causes large currents to impact the motor, battery and controller; when climbing hills, they even twist the handlebars as much as they can to increase the current, hoping to go all out. Climb the slope with energy instead of getting off and pushing. These are taboos when using electric vehicles. High current discharge will have serious impact on the battery.
