Daily maintenance of lithium-ion batteries: More than 60% of the battery can provide sufficient energy for the car to start. To avoid using emergency power when the car cannot start, it is recommended to maintain a battery level of over 60% for the power supply. In daily applications, it is still necessary to be able to charge and discharge emergency power sources in a timely manner, such as charging mobile phones or other electronic devices, in order to maintain the vitality of lithium electronics. 1. Newly purchased lithium-ion batteries always have a small amount of battery power, so users can directly use the battery when they receive it, use up the remaining battery power before charging. After 2-3 normal uses, the lithium-ion battery activity can be fully activated. 2. Lithium ion batteries cannot be over discharged, as over discharge can cause irreversible capacity loss. When the machine reminds that the battery is low, it needs to start charging immediately. 3. If lithium batteries need to be stored for a long time (over a month), it is recommended to charge them to 40% -60%. The battery needs to be recharged for 1-2 hours per month for storage time. 4. When not using the instrument, be sure to store it in a dry and cool place. 5. The charging temperature of lithium-ion batteries is between 0 ℃ and 45 ℃. High or low temperatures can greatly affect the battery's lifespan. 6. Avoid placing lithium batteries near heat sources, open flames, flammable and explosive gases, liquids, which may lead to battery leakage, heating, smoking, fire, and explosion.
