In your case, you can use battery cycling, that is, a complete charge and discharge process to keep the battery in optimal condition and recover from losses.
How to cycle the battery:
1. Fully charge the battery when it is turned off;
2. Turn it on and let it discharge automatically until it is turned off; it's empty. It is best not to operate the computer;
3. It doesn't matter if it's fully charged or not.
If the battery is not used for a long time, it will first discharge until it runs out of power, and may even become incapable of being activated. At the same time, it may cause loss. of real capacity. It is therefore recommended to recharge the battery (to 70%) every two or three months to prevent it from automatically discharging until its battery runs out.
How to repair a 12 V battery thatis not powered?
If the lithium battery has been left for a long time and cannot be charged, do not throw it away. You can try the following methods: activation method, deep charge method, freezing method.
1. Activation method
If the lithium battery is in an over-discharge state and the energy is basically exhausted, so that it is as low as the cut-off voltage off the battery lithium, the activation method can be used, but it does not necessarily work. For example, you can try to slowly charge it with a low-current power source (like a USB port) to restore it slowly, or use a professional charger to activate it.
2. Deep charging method
Deep charging involves fully charging the lithium battery until it is exhausted. In this process, the reaction products in the bBattery can be completely and effectively disposed of, thereby achieving the purpose of battery recycling. However, before you start charging, make sure that the battery will not overheat, otherwise it will damage it.
3. Freezing method
In the frozen state, placing the lithium battery in a low temperature environment can reduce its internal chemical reaction speed, thereby playing a certain repair role. In order to avoid excessive damage, the freezing time generally cannot be too long, generally 6-8 hours after freezing. Additionally, in freezing weather, be careful not to let the battery get wet or come into contact with other metal objects, otherwise it may cause a short circuit.
The working principle of the lithium battery
The lithium battery is a rechargeable battery. Its operating principle is based on the movement of li ionsthium between the positive and negative electrodes. . Carry out the conversion and storage of electrical energy. When a lithium battery is charged, an external power supply supplies current and the lithium ions in the positive electrode are oxidized into lithium ions and electrons. Lithium ions pass from the positive electrode through the electrolyte and enter the negative electrode. At the same time, the electrons return to the positive electrode via the external circuit, thus completing the current closure. When a lithium battery is discharged, lithium ions flow from the negative electrode to the positive electrode, and electrons also flow from the negative electrode to the positive electrode through the external circuit.
In this process, the movement of lithium ions between the positive and negative electrodes causes changes in the potential difference between the positive and negative electrodes, thus generatingelectric energy. The operating principle of lithium batteries is based on the chemical reaction of lithium ions between the positive and negative electrodes. During charging, the lithium ions of the positive electrode are oxidized and the lithium ions of the negative electrode are reduced. During discharge, the lithium ions on the positive electrode are reduced and the lithium ions on the negative electrode are oxidized. This back-and-forth movement of lithium ions allows the conversion and storage of electrical energy.

As an automobile power distribution device, its advantages and disadvantages Disadvantages affect the use of automotive power distribution. installations, and will also harm the operation of the car. It is very common for the battery to be discharged. If the battery is discharged, its life may have expired, which couldresults in a reduction in the storage capacity of the battery. This may also be caused by insufficient electrolyte level of the lithium battery. or insufficient voltage in the battery. However, the most important thing is knowing how to fix a dead battery. Let's see below.
In general, the lifespan of a car battery is around 2 to 3 years. If it is used for a long time, its capacity may decrease and it will not store electricity at that time. you may consider replacing it with a new battery. If the electrolyte of the lithium battery is insufficient, you can add a small amount of pure water or mineral water to the battery, but do not use drinking water, which will shorten the life of the battery. battery.
The voltage of the car battery is generally 12V, and the voltage of 12V is not stable. Under normal circumstances, the battery voltage before the car does note rolling is between 11.8V and 12.8V, and the battery voltage after operation is between 13.2 and 14.8V. If the battery voltage is lower than 11.8V, this means that the tension is not sufficient; If the voltage is lower than 10.8V, it means the battery is discharged and should be activated immediately with a battery charger. Additionally, if the battery voltage is lower than 10V, the battery cannot be charged. At this time, the high-strength repair of the repair instrument should be used to increase the voltage above 10V, so that the battery can be charged.
