How can lithium batteries last longer

1. Timeliness of charging: (1) The battery is generally in a charged half-charged state when leaving the factory. When riding for the first time, it is best to overflow the battery, because the self-discharge will reduce the charge of the lithium battery, and the active material in it can be activated. (2) Do not run out of battery power every time you ride, because over-discharge can cause great damage to lithium batteries. Long-term over-discharge will reduce the battery life by 3 times. At the very least, when the battery is too low while riding an electric bike, stop riding decisively and charge the lithium battery. 2. Timeliness of charging: (1) Lithium batteries are effective at any time, even if there is 50% of the charge before charging, it does not matter. This is because it is different from the nickel-hydrogen battery, which has a memory effect. There is no lithium battery. (2) Do not overcharge. Stop charging when the charging completion indicator is on. 3. Charging to make up for self-discharge: If the battery is not used for a long time, it must be charged once within 60 to 90 days, because the best storage state of the lithium battery is half-electric storage (that is, 40% to 60% of the nominal capacity of the battery). We know that the maximum voltage of a lithium battery is 4.2V. Therefore, the storage voltage is preferably between 3.8V and 3.9V. At this time, the capacity is basically half. 4. Original charging equipment: try to use the original lithium battery charger to charge. The original charger has strong supporting performance and moderate charging rate. At present, there are some fast charging piles. It is recommended that they cannot be used longer. Use it once or twice during the year. Excusable. Excessive current charging will also cause greater damage to the internal structure of the battery. 5. Temperature environment during storage: The temperature environment of polymer batteries is relatively wide, ranging from -20°C to 45°C, but in fact the most suitable temperature is room temperature. From the perspective of aging, temperature may be an important reason for the gradual decline of lithium battery capacity. For countries like my country with large temperature differences, the northern region must develop low-temperature-resistant lithium batteries, while the southern region must develop high-temperature-resistant lithium batteries. 6. Strictly follow the precautions in the manual: When the lithium battery is not in use, place it in a cool and ventilated place, guard against high temperature and humidity, and try to guard against riding in rainy weather. Even if you are riding, you must take care to prevent the lithium battery from entering water. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
