Precautions for use and maintenance of lithium battery pack
1. Precautions for lithium battery charging:
It is strictly forbidden to charge the lithium battery from the discharge terminal, and the matched special charger must be used to charge it from the charging socket. When the charging indicator bar on the charger stops rolling, please remove the charging plug in time to avoid overcharging the battery.
2. Discharge precautions:
The lithium battery pack has the overcurrent protection function. When the use current of the electrical equipment exceeds the maximum output current of the product, the overcurrent protection circuit acts, making the electrical equipment seem unable to work normally.
3. Precautions for daily use:
The output of the discharge terminal is not controlled by the switch on the panel. Only when the battery voltage is lower than 9.0V, the discharge terminal will turn off the output. The switch on the panel controls the output of the display screen and USB socket. When the switch is turned on and the battery voltage is ≤ 9.1V, the display screen will flash to remind you that you should charge in time at the frequency of one second on and one second off. When the battery voltage is ≤ 9.0V, the display screen will go off and the USB socket is closed for output, so as to protect the lithium battery from excessive discharge. Although it has the output short circuit protection function, it should not frequently short circuit the+and - power outputs in daily use.
4. Precautions for recycling:
The normal cycle charge and discharge times of lithium battery are about 500~800 times, and the lithium battery at the end of its life shall be recycled and disposed according to local laws.
5. Operating environment and maintenance method of lithium battery:
☀ The charging temperature of lithium battery shall be 0℃~45℃, and the discharge temperature of lithium battery shall be - 20℃~60℃;
☀ In a clean, dry and ventilated environment, avoid contact with corrosive substances and keep away from fire and heat sources;
☀ The lithium battery pack has no memory effect and can be charged when used. However, it should be noted that the lithium battery cannot be over discharged, which will cause very large capacity loss;
☀ Do not mix the battery with metal objects to avoid metal objects touching the positive and negative electrodes of the battery, causing short circuit, damage to the battery and even danger;
☀ Avoid frequent overcharging. Overcharging will raise the temperature inside the battery to a very high level, which is harmful to lithium ion batteries and chargers. Therefore, as long as the battery is fully charged, it will be enough to turn your lithium battery into a small bomb.
Conclusion: The battery is a consumable, and its life is certain (charging and discharging times are usually 300-500 times). Therefore, mastering the correct use method is the secret of "prolonging the life" of the battery.
6. Battery maintenance:
Charging: The safe working voltage range of lithium battery is 2.8~4.2V. The lithium ion in the battery becomes very unstable below or above this voltage range, even causing accidents. To ensure that the battery is in a safe range, a special charger is required.
Lithium battery shall be charged and discharged once every three months to restore its original performance.
Before use, lithium batteries should be checked to see if they meet the load requirements. If they cannot meet the load requirements or are used with high current (more than 1C), the battery will be damaged or its life will be shortened.
Avoid frequent use in high or low temperature environments. It is better to be at room temperature, and the temperature will have a great impact on the characteristics of lithium battery.
7. Advantages of energy storage electrical lithium iron phosphate battery pack:
✔ Long service life, lithium iron phosphate battery, cycle life of more than 2000 times, standard charging (5 hour rate) use, can reach 2000 times.
✔ High temperature performance, lithium iron phosphate electrothermal peak can reach 350 ℃ - 500 ℃. The working temperature range is wide (- 20C -+75C), and the lithium iron phosphate electric heating peak can reach 350℃ - 500℃ with high temperature resistance.
✔ It is safe and reliable. The P-O bond in lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat like lithium cobalate or form strong oxidizing substances, so it has good safety.
✔ No memory effect. Rechargeable battery works under the condition that it is always in full charge. No matter what state the battery is in, it can be used as soon as it is charged, without having to discharge before charging.
✔ Small size, light weight and large capacity. The volume of lithium iron phosphate battery with the same specification and capacity is 2/3 of that of lead-acid battery, and the weight is 1/3 of that of lead-acid battery.
✔ Green and environment-friendly, complying with European RoHS regulations, it is an absolute green and environment-friendly battery.
✔ It has good impulse discharge characteristics. The conversion efficiency of charging and discharging electric energy of lithium battery pack can be more than 97%. Under the same temperature, the discharge output characteristics of lithium battery pack are very stable with different rates of discharge current.
✔ Fast charging: High current 2C fast charging and discharging. The battery can be fully charged within 40 minutes after charging at 1.5C with a special charger, and the starting current can reach 2C.
In a word, form a good habit, treat your lithium battery well, maintain it regularly, and use it correctly, so that the life of the lithium battery pack will be greatly extended.
