Lithium batteries can be found everywhere in our daily life, and lithium batteries are needed for cell phones, computers, and electric cars used in our daily life. But how to maintain lithium batteries in our daily life?

So that lithium batteries can be maintained at the optimal level, and the safe use of lithium batteries to achieve the longest battery life, we need to check the lithium batteries in the day-to-day, the correct treatment of charging and discharging, to ensure that the battery is located in the appropriate temperature, etc., the specific maintenance steps are as follows:

Regular inspection of lithium batteries

1. Check the appearance of lithium batteries

1.1 Check the appearance for dents or protrusions, which may affect the integrity of the shell and affect the use.

1.2 Check the appearance whether there is a crack or crack phenomenon, there are cracks or cracks will occur in the accident of leakage.

1.3 Check the appearance of the lithium battery whether there are foreign objects or pollution, there are foreign objects or pollution will affect the performance of the battery, reduce the use of battery efficiency.

2. Check the wiring harness connection status of the lithium battery

2.1 Check the lithium battery connection harness insulation, whether there is a phenomenon of damage, if there is damage will have the possibility of leakage.

2.2 Check whether the connection terminals of the lithium battery harness are connected reliably to improve the performance of the battery.

3.Check the voltage of the lithium battery

Fully charge the lithium battery, use a multimeter to check the battery voltage, when the voltage is 0 or very low, it means that the battery internal short circuit or battery damage, you need to replace the battery.

Proper Charging and Discharging

1. Precautions for first time charging

When we use lithium battery for the first time, we need to charge the battery when the power drops to 50%. You need to read the instruction manual that comes with the product to ensure that the battery is charged correctly.

2. Use a special charger for lithium batteries

Use a charger designed for lithium batteries, you can adjust the charging amount according to the battery charging situation, which will reduce the risk of damage to the battery, when the battery is fully charged, lithium battery charger will adjust the charging current to prevent overcharging and increase the lifespan of the battery. If you have to use a universal charger, you can unplug the charger when the power is charged to about 80%.

3. Avoid overcharging

The optimal working condition of lithium batteries is within the range of 20% to 80% charge, overcharging will trigger oxidation, corrosion and other reactions, so that the solvent in the electrolyte decomposition, will produce a large amount of hydrogen, oxygen and other flammable gases, resulting in the internal pressure and temperature of the battery, and may even cause explosions, fires and other accidents. Overcharging should be avoided under all circumstances to avoid damaging the lifespan of the battery and to maintain the optimal level of the battery.

4. Avoid over-discharging

Batteries also need to avoid overcharging. When the battery is full, unplug the charger in time. Over-discharging will damage the internal structure of the battery, affecting the capacity and cycle life of the battery, and may lead to premature failure, rendering the battery unusable.

Temperature and Condition

1. Avoid leaving lithium batteries in a high-temperature state

Lithium batteries can work and use in the temperature range of 0℃ to 35 ℃, 16℃ to 25℃ is the ideal working temperature zone, and can be stored in the negative 20℃ to 45℃ under certain restrictions. However, it is important to stay away from high temperatures, lithium batteries become hot, the power will drop, the efficiency will be reduced, will seriously affect the service life of the battery. If charged or stored in a high temperature environment, it may permanently damage the battery capacity, and the service life of the battery will be further reduced, ultimately resulting in the battery can not be used.

2. Avoid leaving lithium batteries at low temperatures

We want to protect the battery and equipment from the effects of extreme cold weather. Batteries work best at temperatures between 20℃ and 60 ℃. In cold environments, the discharge capacity and discharge energy of lithium batteries will decrease, and if they are in colder environments, the internal resistance will increase, which will diminish the battery’s endurance and cause the battery’s capacity to decrease. If the temperature below zero will lead to crystallized material inside the battery, causing great damage to the battery.

3. Do not subject lithium batteries to severe impacts

When using lithium batteries, avoid violent vibration and shock. If it is subjected to external violent shocks, it will cause the battery to short-circuit and thermal runaway of the battery may occur.

Battery Storage

1. Store batteries fully charged and charge them regularly

When we do not use the battery, we need to fully charge the battery before storage, because with the passage of time, the battery’s power will gradually drain. In order to prevent lithium batteries from running out of power, we can store them for a period of time when they are fully charged, and then charge them regularly to keep them in the best state of charge, which will increase the service life of the batteries and improve the recycling rate. If you don’t charge regularly, the battery will still consume light electricity, affecting the battery life.

2. Lithium battery storage to avoid direct sunlight and humid environment

Lithium battery storage should avoid direct sunlight, in direct sunlight, the battery can not be fully discharged, will accelerate the chemical reaction, shorten the service life of the battery, may also occur irreversible damage, such as battery bulging, sulfation, etc.. If stored in a humid environment will reduce the performance of the battery, resulting in a short circuit of the battery, and in serious cases, a fire will occur.

3. Use of battery storage boxes, etc.

In the battery storage process, the use of battery storage box can avoid the influence of other external environment. Battery storage environment temperature should be controlled at about 20 ℃, relative humidity should not be greater than 75%, you can use dehumidifiers to control the storage humidity, you can also use desiccant.

4. Avoid contact with other metal objects

When storing lithium batteries, avoid contact with other metal objects, so as not to contact the positive and negative poles of the battery, resulting in a short circuit, damage to the battery, and even a threat to personal life, health and safety.

Battery transportation

1. Avoid stacking batteries together

When we buy new batteries to transport home, or transport old batteries to the recycling station, to avoid stacking batteries together, because it may cause physical damage, which may lead to a short circuit or fire. Proper lithium battery maintenance procedures should be followed to help ensure longevity while minimizing the risk of accidents during transportation.

2. Transportation environment should be appropriate

During transportation, attention should also be paid to the temperature of the battery, the battery state, the environment, etc., to ensure that the battery is safely transported without short-circuiting, fire and other phenomena.

Summary

Understanding the basic knowledge of lithium batteries and their maintenance is extremely important for daily use. We need to maintain the correct charging habits, correct storage of batteries, etc., as well as comply with safety measures to extend the service life of the battery, only responsible treatment of lithium batteries in daily life, in order to maximize the use of batteries.
