There is current when the 12 volt lithium battery is folded, but there is no current at the wiring t

There are two possibilities. The first is that the

external binding terminals

exhibit an oxide layer after long-term use, resulting in

poor contact.

< p>, the second is that the virtual connection between the terminals and

connecting wires

inside the battery causes the

to increase, or simply

, which results in no external voltage measurement.

How to maintain the battery if it is not used for a long time?

In fact, this phenomenon is common. It's not that a battery is of poor quality, but it involves the characteristics of the lithium-ion battery itself: its performance at low temperatures. At low temperatures, the performance of lithium-ion batteries decreases, the voltage appears “falsely low”, the self-protection system is activated and the batteryrie turns off automatically. The nominal capacity of the battery is tested at room temperature (25 degrees Celsius). The capacity released at low temperature is much lower than this value, only 40% or even lower, which is related to temperature. This is why people think that batteries are not durable.

The storage capacity of some batteries decreases when temperatures drop. In winter, especially in environments below 25 degrees, the energy storage capacity of electric vehicles will weaken, and the energy storage capacity will weaken even more significantly. The positive and negative electrodes of a battery are electrolytes. During use, the negative electrode generates electrons, and the electrons enter the positive electrode through the electrolyte to form an electric current. Therefore, court generationElectrical ant is actually a chemical reaction process.

One of the factors that affects the rate of chemical reactions is temperature. When the ambient temperature is too low, the resistance of the electrolyte increases, the chemical reaction rate decreases and the current generated is relatively reduced. Therefore, the reason for the increase in battery power consumption in low temperature environments is actually that the current generated by the battery is reduced, resulting in a reduction in available power, so that it will experience greater energy consumption when using it.

Routine Battery Maintenance 1. When the vehicle is parked for a long time, remove the battery buckle. If it is not dismantled in time, leakage will occur and affect the performance of the battery. 2. Hot water can effectively remove corrosionnot. After removal, it is best to apply butter to the pile heads to prevent corrosion. Therefore, as long as we do these two things well, we will never again feel that the battery is not durable.

Care and maintenance of the battery: 1. When the battery is not used, it should be charged once or twice a month to keep it in good condition. 2. When not used for a long time, the battery ground wire should be disconnected. 3. The battery charging current cannot be too large, and the charging voltage cannot be higher than 20% of the battery voltage. It should be charged at a current of one twentieth of the battery capacity and charged continuously for 24 hours. Try not to charge quickly and with high current (ten hours of charging). This can easily cause the battery to generate high temperatures and even reach summerat boiling of the battery electrolyte, affecting its lifespan. 4. Check the electrolyte level frequently and add water in time to reach the standard water level.Little. 5. Clean the battery electrode stacks frequently and keep them dry to ensure good contact. If the battery is not required for normal maintenance for an extended period of time, it should be left fully charged and left alone. After that, it should be charged once a month to allow the battery to perform the necessary chemical reactions the next time it is used. time, it must be fully charged and discharged. Once fully charged, it can be used normally. If you do not charge it for a long time, the plates will be vulcanized and the lead powder will fall off or even be discarded. If you maintain it like this, it will last for a year (if you don't want to remove it from the car, simply unplug thehe positive and negative cables to avoid long-term use. If no one cares about the weather, the). wire nuts will oxidize and corrode). 1. Use a damp cloth to scrub the exterior of the battery and wipe off dust, oil, white powder and other contaminants that may cause leakage on the panel and battery heads (i.e. the positive and negative poles). By frequently wiping the battery in this manner, white acid-etched powder will not accumulate on the battery's cell head and its life will be longer. 2. Open the battery water cap and check whether the water level is normal; position. Generally, there are upper and lower limit markings on the side of the battery. If the water level turns out to be lower than the lower marking line, distilled water should be added. If distilled water cannot be obtained immediately, filtered tap watercan be used. be used in an emergency. Don't add too much water, the standard is to add some in the middle of the top and bottom markings.
